Abstract:
Synthetic hexaploid wheat (SHW) has shown effective resistance to a diversity of diseases and insects, including tan spot, which is caused by Pyrenophora tritici-repentis, being an important foliar disease that can attack all types of wheat and several grasses. In this study, 443 SHW plants were evaluated for their resistance to tan spot under controlled environmental conditions. Additionally, a genome-wide association study was conducted by genotyping all entries with the DArTSeq technology to identify marker-trait associations for tan spot resistance. Of the 443 SHW plants, 233 showed resistant and 183 moderately resistant reactions, and only 27 were moderately susceptible or susceptible to tan spot. Durum wheat (DW) parents of the SHW showed moderately susceptible to susceptible reactions. A total of 30 significant marker-trait associations were found on chromosomes 1B (4 markers), 1D (1 marker), 2A (1 marker), 2D (2 markers), 3A (4 markers), 3D (3 markers), 4B (1 marker), 5A (4 markers), 6A (6 markers), 6B (1 marker) and 7D (3 markers). Increased resistance in the SHW in comparison to the DW parents, along with the significant association of resistance with the A and B genome, supported the concept of activating epistasis interaction across the three wheat genomes. Candidate genes coding for F-box and cytochrome P450 proteins that play significant roles in biotic stress resistance were identified for the significant markers. The identified resistant SHW lines can be deployed in wheat breeding for tan spot resistance.

Abstract:
Reference populations are valuable resources in genetics studies for determining marker order, marker selection, trait mapping, construction of large-insert libraries, cross-referencing marker platforms, and genome sequencing. Reference populations can be propagated indefinitely, they are polymorphic and have normal segregation. Described are two new reference populations who share the same parents of the original wheat reference population Synthetic W7984 (Altar84/ Aegilops tauschii (219) CIGM86.940) × Opata M85, an F1-derived doubled haploid population (SynOpDH) of 215 inbred lines and a recombinant inbred population (SynOpRIL) of 2039 F6 lines derived by single-plant self-pollinations. A linkage map was constructed for the SynOpDH population using 1446 markers. In addition, a core set of 42 SSR markers was genotyped on SynOpRIL. A new approach to identifying a core set of markers used a step-wise selection protocol based on polymorphism, uniform chromosome distribution, and reliability to create nested sets starting with one marker per chromosome, followed by two, four, and six. It is suggested that researchers use these markers as anchors for all future mapping projects to facilitate cross-referencing markers and chromosome locations. To enhance this public resource, researchers are strongly urged to validate line identities and deposit their data in GrainGenes so that others can benefit from the accumulated information.

Abstract:
This work reports the synthesis and evaluation of barakol tailored to become biodiesel fluorescent markers. Fluorescent markers for biodiesel fuels were synthesized from the reaction between barakol, which was obtained from the leaves and flowers ofCassia siameLamk., with acid chloride in the presence of triethylamine. These synthetic fluorescent markers were 7-lauroyloxy-5-acetonyl-2-methylchromone, 7-butyryloxy-5-acetonyl-2-methylchromone and 7-(2-ethyl)-hexanoyloxy-5-acetonyl-2-methylchromone. These synthetic fluorescent markers were invisible color in biodiesel fuels when they were added into biodiesel and quantitative measurement was carried out using spectrofluorometer. All compounds gave fluorescence at 612 nm when they were excited at 464 nm. The testing results of fuel properties using the ASTM test methods revealed that the physical properties of the marked biodiesel fuels were similar to those of the unmarked biodiesel fuels. Moreover, those synthetic fluorescent markers were found to be stable in diesel fuels for at least three months at a concentration of 4 ppm.

Abstract:
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most important diseases affecting wheat. In this study, seven gene-linked markers were used to identify the presence of stripe rust resistant genes in 51 accessions of synthetic hexaploid of wheat which were found to be resistant at seedling plant stage. Molecular marker-based gene identification showed the presence of Yr5, Yr10 and Yr15 in three accessions, Yr36 in three accessions, Yr48 in seven accessions, YrR61 in four accessions, and YrTP1 in ten accessions of resistant hexaploid of wheat. These gene-linked markers were also used for the detection of genetic diversity. A total of 68 alleles were detected by these seven gene-linked markers. The mean number of allele was 11.3 alleles per locus. Genetic diversity values ranged from 0.34 to 0.93, with highest genetic diversity value of 0.93 detected for marker Xwm477. The lowest genetic diversity value was observed for marker Xbarc167. The polymorphic information content value ranged from 0.33 to 0.92 with an average of 0.54. The highest number of alleles (n= 24) were detected for marker Xwmc477. The evidence in this study on the basis of genetic diversity and presence of Yr genes in synthetic hexaploid wheat accessions will be useful in further breeding programmes.

Abstract:
Context.— Synthetic urine products are commercially marketed for the purpose of specimen substitution for urine drug screens. These products are widely popular because they yield negative drug screen results, meet criteria for specimen validity testing, and are easily accessible and affordable. Current specimen validity criteria are ineffective for detecting these synthetic products, and new markers of specimen validity are required. Objective.— To develop and evaluate a multicomponent liquid chromatography tandem mass spectrometry (LC-MS/MS) assay for urine specimen validity testing. Design.— A quantitative LC-MS/MS assay was developed for caffeine, cotinine, theobromine, and urobilin in urine. The assay was applied to known synthetic urine products (n = 10) as well as human specimens received for pre-employment testing (n = 500), for-cause workplace testing (n = 100), and medical pain management monitoring (n = 200). Specimens devoid of all 4 validity markers were subjected to follow-up testing that involved microscopic urinalysis and comprehensive gas chromatography mass spectrometry for drugs, pharmaceuticals, hormones, and lipids. Results.— Of the experimental groups, 10 of 10 synthetic urine products (100%), 12 of 500 pre-employment specimens (2.4%), and 4 of 200 pain management specimens (2.0%) failed the experimental LC-MS/MS assay. Follow-up testing indicated that each of the failed specimens was nonphysiologic in nature. Conclusions.— Simultaneous application of the 4 experimental validity markers appeared to be a robust method for detecting nonphysiologic specimens. New markers of specimen validity must be developed in order to identify commercially available synthetic urine products.

Abstract:
Background: There has been aroused demand for herbal drugs/products worldwide because of their fewer side effects as compared to synthetic drugs. The major obstacle in the global acceptance of herbal products is the lack of proper standardization technique. Methods: Various test procedures have been used for authentication and quality control of botanicals among which marker based standardization has attained more attention. The major challenge faced by phytochemist is to select appropriate phytochemical marker for quality control of herbal drugs. Phytochemical markers used for standardization must be of known purity. Phytochemical markers which are not commercially available have to be isolated from respective medicinal plants. Various chromatographic techniques are reported for the purification of phytomarkers from plants. A comprehensive report on different purification techniques of isolation of phytochemical markers through in-depth review of scientific literature is required. Conclusion: This article highlights various classifications of phytochemical markers along with their applications in standardization of herbal drugs and various classical and modern analytical techniques for their isolation.

Abstract:
Augmented reality can be deployed in various application domains, such as enhancing human vision, manufacturing, medicine, military, entertainment, and archeology. One of the least explored areas is the underwater environment. The main benefit of augmented reality in these environments is that it can help divers navigate to points of interest or present interesting information about archaeological and touristic sites (e.g., ruins of buildings, shipwrecks). However, the harsh sea environment affects computer vision algorithms and complicates the detection of objects, which is essential for augmented reality. This paper presents a new algorithm for the detection of fiducial markers that is tailored to underwater environments. It also proposes a method that generates synthetic images with such markers in these environments. This new detector is compared with existing solutions using synthetic images and images taken in the real world, showing that it performs better than other detectors: it finds more markers than faster algorithms and runs faster than robust algorithms that detect the same amount of markers.

Abstract:
Using synthetic peptide or recombinant protein as immunising antigens we have produced monoclonal antibodies and polyclonal antisera directed against targets of particular interest in leukaemia diagnosis. In this way we have prepared reagents which recognise all T or all B lymphocytes in routinely fixed paraffin sections which are unique in this respect. We have also produced monoclonal antibodies to molecules potentially involved in specific neoplastic transformations, implicated by virtue of the involvement of their genes in chromosomal defects in these neoplasms. In particular, we have produced antibodies recognising bcl-2, involved in follicular lymphoma, tal-1, involved in T-cell acute leukaemias and HRX involved in a variety of hematologic disorders. The application of these reagents to diagnosis has so far proved useful. In addition their use outside the field of leukaemia diagnosis has proved to be even more important in some cases.

Relevance of the topic Nowadays navigation services have become an integral part of our lives. The vast majority of mobile devices support global GPS positioning. However, it is not possible to use it inside buildings. In these cases, specific technologies that often require modified mobile devices have to be developed. On the IPIN market, the main approach now is to use BLE beacons and signals from existing Wi-Fi access points. However, both methods require considerable investment of money and time. Today's smartphones have reached a level of performance that supports real-time camera image stream processing and determining the relative movement of the device. The combination of these factors makes the development of optical positioning systems for mobile devices extremely relevant. The purpose of research is the creation of a positioning subsystem for the mobile indoor navigation application, which helps users to find away to the points of interest and accompanies to them by providing interactive instructions using augmented reality. To achieve this goal, we need to complete the following research objectives: — to consider, analyze and compare methods of indoor position determination; — to develop an indoor positioning service based on the chosen approach; — integrate the subsystem with other components of the software product. Object of study: Indoor positioning methods based on computer vision. Subject of study: A visual-inertial indoor positioning system for navigation using smartphones. Research methods: To solve the problem, we use software architecture design methods, theory of data flows modeling, object-oriented analysis of the domain. Scientific novelty: Internal positioning system has been improved by combining visual-inertial odometry with synthetic markers, which has led to the possibility of developing a localization system without deploying expensive devices for receiving or transmitting signals. Practical meaning is that the developed application can be used for the purposes of finding rooms in educational buildings, as well as for object annotation. The functionality of the application allows you to replace the map of the facility to reuse in other fields. Approbation. The results of the research were discussed at the 17th Scientific and Practical Conference of Young Scientists and Students "Modern Problems of Scientific Support for Energy" held in Kyiv, April 23-26, 2019.Structure and volume of the thesis The master's thesis consists of an introduction, five sections and conclusions, a list of references with 46 sources; includes 25 figures, 25 tables and 2 appendices. The full amount of work is 112 pages, 5 of them — references list and appendices — 13 pages. The introduction substantiates the need to develop new approaches to navigation, sets a research goal, and defines the task of development. The first section describes the concept of navigation. It describes the practical importance of internal positioning systems and their potential applications. Determines place of the subsystem in the resulting application and its data flow. The second section explores the basic techniques and technologies for indoor navigation positioning. Attention is especially focused on the SLAM method. Existing software systems, their advantages and disadvantages are analyzed. An approach combining SLAM and synthetic markers is proposed. Justified the choice of ArUco markers. The third section is devoted to the software implementation of the subsystem. We describe used development tools, structure and configuration of the developed product. The fourth section provides instructions on how to deploy, install, and use the software product — mobile application. The fifth section provides an analysis of possibilities to implement the product as a startup project. We identified development and marketing strategies, conducted a SWOT-and financial analysis and described risk and opportunity factors. The conclusions set out the results of the work and provide recommendations for further research on the topic. The appendices contain the program code of the developed subsystem and the abstracts for the conference where the dissertation materials were discussed.

Lippia alba é uma espécie medicinal com ampla diversidade fenotípica, incluindo a composição do óleo essencial. A variação genética é provavelmente a principal causa dessa variação. A espécie foi descrita como um complexo poliploide com cinco números cromossômicos (2n=30, 38, 45, 60 e 90). Devido à importância econômica e à variação genética natural, essa espécie representa um excelente modelo em estudos sobre estabilidade genômica. Este trabalho teve como objetivo investigar a estabilidade genômica de 22 acessos naturais cultivados in vitro durante sete anos e em acessos poliploides sintéticos obtidos a partir da duplicação cromossômica de um acesso diploide natural usando colchicina. Para analisar a estabilidade do genoma de plantas cultivadas a longo prazo, foram analisadas quatro plantas (três mantidas in vitro e uma no campo) de 22 acessos. O tamanho do genoma foi verificado por citometria de fluxo e oito marcadores ISSR foram utilizados para verificara estabilidade em nível de sequencia de DNA. Para avaliar a estabilidade genômica após a poliploidização, onze plantas poliploides sintéticas, sendo 5 tetraploides (4X) e 6 mixoploides (2X / 4X) foram comparadas com a planta matriz diploide. As comparações foram baseadas no conteúdo de DNA, contagem cromossômica, marcadores moleculares ISSR e SSR e no perfil químico do óleo essencial. A comparação entre as plantas mantidas in vitro e as respectivas plantas mantidas no campo mostrou que 13 dos 22 acessos sofreram uma pequena redução no tamanho do genoma. Os marcadores ISSR detectaram polimorfismos na sequência de DNA variando de 1,61 a 33,87%. Somente três acessos não apresentaram bandas polimórficas. O número de bandas polimórficas entre os outros 19 acessos variou de um a 21. A análise da ploidia das plantas poliploides sintéticas realizada em folhas e raízes confirmou a estabilidade das plantas tetraploides. As plantas mixoploides apresentaram um único pico G1 correspondente a plantas triploides. A análise cromossômica revelou 60 cromossomos com 12 sítios de DNAr 45S nas plantas tetraploides e 9 sítios de DNAr 45S nos 45 cromossomos observados nas plantas triploides. Os marcadores ISSR mostraram polimorfismo entre a planta matriz diploide e as plantas poliploides sintéticas. A taxa de polimorfismo variou de 1,81 a 5,45% nas plantas tetraploides e de 43,63 a 56,36% nas plantas triploides. Alterações no tamanho dos alelos de microssatélites também foram detectadas. A planta matriz diploide apresentou dez alelos, três dos quais foram compartilhados com as plantas triploides e sete com as plantas tetraploides. Todas as plantas triploides apresentaram 13 alelos, sendo dez deles correspondentes a alelos novos. O número de alelos detectados nas plantas tetraploides variou de oito a 11 e o número de alelos novos como consequência da poliploidização variou de dois a quatro. O componente majoritário detectado no óleo essencial da planta matriz diploide e das plantas tetraploides foi o citral e nas plantas triploides foi o linalol. A instabilidade genômica detectada em L. alba após sete anos de cultura in vitro pode ser devido à consequência da instabilidade do genoma natural combinada com a cultura in vitro a longo prazo. Os efeitos da poliploidização que resultam em reorganização genômica e alterações fisiológicas podem explicar a variação observada nas plantas poliploides sintéticas.
Lippia alba is a medicinal species with a broad phenotypic diversity, including the essential oil composition. Genetic variation is probably the main cause of this variation. The species is a polyploid complex with five chromosome numbers (2n = 30, 38, 45, 60 and 90). Due to the economic importance and the natural genetic variation, this species represents an excellent model in studies on the genomic stability. This work aimed to investigate the genomic stability of 22 natural accessions grown in vitro for 7 years and in synthetic polyploid accessions obtained from the chromosome duplication of a natural diploid access using colchicine. To analyze the genome stability of long-term cultivated plants, four replicates (three maintained in vitro and one in the field) of 22 accessions were analyzed. The size of the genome was verified by flow cytometry and eight ISSR markers checked for stability in the DNA sequence. To evaluate the effect of polyploidization, eleven synthetic polyploid plants composed of 5 tetraploids (4X) and 6 mixoploids (2X/4X) were compared with the diploid parent plant. The comparisons were based on DNA content, chromosomal count, molecular markers ISSR and SSR, and chemical profile of the essential oil. The comparison between the plants maintained in vitro and the respective plants maintained in the field showed that 13 of the 22 accessions suffered a small reduction in the size of the genome. ISSR markers detected polymorphisms in the DNA sequence ranging from 1.61 to 33.87%. Only three accessions did not present polymorphic bands. The number of polymorphic bands among the other 19 accesses ranged from 1 to 21. Analysis of the ploidy of the synthetic polyploid plants carried out on leaves and roots confirmed the stability of the tetraploid plants. The mixoploid plants presented a single G1 peak corresponding to triploid plants. The chromosome analysis showed 60 chromosomes with twelve 45S rDNA sites in the synthetic tetraploids and nine 45S rDNA sites over the 45 chromosomes observed in the synthetics triploid plants. ISSR markers showed polymorphism between the diploid parent plant and synthetic polyploid plants. The polymorphism rate varied from 1.81 to 5.45% in the tetraploid plants and from 43.63 to 56.36% in the triploid plants. Changes in the size of the microsatellite alleles were also detected. The diploid parental plant presented 10 alleles, of which 3 were shared with the triploid plants and 7 with the tetraploid plants. All triploid plants had 13 alleles, 10 of which correspond to new alleles. The number of alleles detected in tetraploid plants ranged from 8 to 11 and the number of new alleles as a consequence of polyploidization ranged from 2 to 4. The major component detected in the essential oil of the parental diploid plant and the tetraploid plants was the citral and the triploid plants was the linalool. The genetic instability detected in L. alba after seven years of in vitro culture may be due to the consequence of natural genome instability combined with long-term in vitro culture. The effects of polyploidization that result in genomic reorganization and physiological changes may explain the variation observed in synthetic polyploid plants.

This dissertation consists of three essays in applied financial economics. The unifying theme is the use of financial regulation as quasi-experiments to understand the interrelationship between derivatives and the underlying assets. The first two essays use different quasi-experimental econometric techniques to answer the same research question: how does option listing affect the return volatility of the underlying stock? This question is difficult to answer empirically because being listed on an options exchange is not random. Volatility is one of the dimensions along which the options exchanges make their listing decisions. This selection bias confounds any causal effect that option listing may have. What is more, the options exchanges may list along unobservable dimensions. Such omitted variable bias can also confound any causal effect of option listing. My first essay overcomes these two biases by exploiting the exogenous variation in option listing that is created by the SEC-imposed option listing standards. Specifically, the SEC mandates that a stock must meet certain criteria in the underlying market before it can trade on an options exchange. For example, a stock needs to trade a total of 2.4 million shares over the previous 12 months before it can be listed. Since 2.4 million is an arbitrary number, stocks that are “just above” the 2.4 million threshold will be identical to stocks that are “just below” it, the sole difference being their probability of option listing. Accordingly, I use the 2.4 million threshold as an instrument for option listing in a fuzzy regression discontinuity design. I find that option listing causes a modest decrease in underlying volatility, a result that corroborates many previous empirical studies. My second essay attempts to estimate the effect of option listing for stocks that are “far away from” the 2.4 million threshold. I overcome the aforementioned omitted variable bias by fully exploiting the panel nature of the data. I control for the unobserved heterogeneity across stocks by implementing a two-way fixed effects model. Unlike most previous studies, I control for individual-level fixed effects at the firm level rather than at the industry level. My results show that option listing is associated with a decrease in volatility. Importantly, these results are only statistically significant in a model with firm-level fixed effects; they are insignificant with industry-level fixed effects. My third essay is a policy evaluation of the SEC’s Penny Pilot Program, a mandated decrease of the option tick size for various equity options classes. Several financial professionals claimed that this decrease would drive institutional investors out of the exchange-traded options market, channeling them into the opaque, over-the-counter (OTC) options market. I empirically test an implication of this hypothesis: if institutional investors have fled the exchange-traded options market for the OTC market, then it may take longer for information to be impounded into a stock’s price. Using the `price delay’ measure of Hou and Moskowitz (2005), I test whether stocks become less price efficient as a result of being included in the Penny Pilot Program. I perform this test using firm-level fixed effects on all classes that were included in the program. I confirm these results with synthetic control experiments for the classes included in Phase I of the Penny Pilot Program. Generally, I find no change in price efficiency of the underlying stocks, which suggests that the decrease in option tick size did not materially erode the price discovery that takes place in the exchange-traded equity options market. I also find evidence that the decrease in option tick size caused an increase in short selling for the piloted stocks.

Full text
Abstract:
Abstract A single-camera synthetic Schlieren method is introduced here to measure two-dimensional topography and depth of dynamic free liquid surfaces. The method is simple and easy to implement. Because of light refraction (following Snell’s law), markers on a flat bottom which are seen through the surfaces of a transparent liquid are virtually displaced. This leads to a governing equation that the liquid surface depth (and its topography) is associated with the marker displacement. In the equation, the refractive index of the liquid (e.g. water) can be obtained by a refractometer (or from a technical reference), and the displacements of the markers can be obtained by a cross-correlation method which is usually used in particle image velocimetry. In the equation, the only unknown, the depth of the surface, can be obtained by solving the governing equation with boundary conditions. Unlike free-surface synthetic Schlieren (FS-SS) of Moisy et al. (Exp. Fluids, 1021, 46, 2009), our method does not require a reference depth (which is obtained before or after experiments), so that flows with temporally evolving depth can be measured. Experiments of liquid ripples and dam-break flows were performed to test the method. The results agree well with those obtained with FS-SS and visualization measurements.

Abstract:
Abstract The main objective of the study is to compare the results of the cross-well tracers survey against the pulse code pressure interference testing (PCT) for the complicated geological structures. The study was based on the numerical simulations on the synthetic 3D models with popular geological complications, such as faults, vertical and horizontal reservoir anisotropy and pinch-outs. The study has set a special focus on quantitative analysis of the reservoir properties estimated by tracers and PCT as against the known values. This provides a text-book examples of advantages and disadvantages of both surveillance methods in different geological environment. Pulse code testing is specific implementation of pressure interference testing by creating a series of injection/production rate changes accordingly to a preset schedule to create a "pressure code" and monitoring the pressure response in the offset wells. The use of high-resolution quarts gauges is highly beneficial in case of large cross-well intervals scanning or poor reservoir quality in case of regular inter-well spacing. The tracer survey is based on injecting a liquid with chemical markers and subsequent capturing the markers at surface samples in the offset wells. The modern markers are relatively cheap and can be captured at very low concentrations thus making the cross-well scanning available even for high inter-well spacing. For synthetic models with vertical inhomogeneity the PCT provides a close estimate for compound dynamic reservoir properties (transmissibility and pressure diffusivity). For synthetic models with lateral inhomogeneity the PCT provides an accurate estimation for effective reservoir thickness and permeability. Tracers survey is not able to assess the reservoir thickness. The popular methods to assess reservoir permeability from tracers survey show a substantial deviation from the true reservoir permeability for synthetic models with vertical and lateral heterogeneity. This leads to conclusion that the most reliable application of racers survey is a qualitative assessment of cross-well connectivity and quantitative estimate of permeability in homogenous reservoirs. The first study of quantitative comparison of tracer survey against pressure pulse-code interference survey. Tracer survey and PCT efficiency was compared on 3D numerical models. Presence of synthetic models, describing geological complications, which may be seen very often on real reservoirs, provides a reliable basis for comparison.

Abstract:
In Kyoto bow fabrication, in order to bond each material, the glue which is made from the skin of the deer (Nibe) has been traditionally used. Recently, the synthetic adhesive is used instead of Nibe. The purpose of this study is to clarify the effects of the type of adhesive on the performance for the archer to draw Kyoto bow (Nibe bow and Synthetic bow). The measurement of motion was performed using MAC 3D system, and in order to clarify the relationships between the deformation and the load required to draw of the Kyoto bow, the motion analysis of the archer during the drawing motion of the Kyoto bows was performed by attaching markers and load cell onto the bows. In addition, the velocity of the arrow was calculated by the image processing. The loads and the maximum velocities of arrow with both bows were similar, however the arrow of Nibe bow drastically accelerates rather than that of Synthetic bow at the some point. Additionally, the time required to draw the bow of Nibe bow was significant shorter than that of Synthetic bow.

Full text
Abstract:
A new process for converting natural gas into liquid fuels and other petroleum products is described, as is the increased market opportunity this technology portends for gas turbine manufacturers. The GTL technology, developed by Syntroleum Corporation, utilizes Autothermal Reforming with air to produce a nitrogen-diluted synthesis gas having a near ideal ratio for converting into synthetic hydrocarbons via Fischer-Tropsch synthesis. A proprietary catalyst system achieves conversion rates comparable to conventional F-T processes without the need for recycling. This results in plant capital costs low enough to make conversion of remote and/or sub-quality gas into synthetic fuels economical at current oil prices. The process is energy self-sufficient and compact enough to be constructed in small sizes for plants in remote areas, including floating or platform facilities to utilize offshore gas reserves. It can also be scaled up for 50,000 BPD or larger applications.

Abstract:
Five stocks of tilapia [oreochromis niloticus (on), red O. niloticus (ROn), O. aureus (Oa), O. mossambicus (Om), and Sarotherodon galilaeus (Sg)] were used to produce two-way (F1), three-way (3WC) and four-way crosses (4WC). Three 4WC groups, containing equal representation of all four species, formed the base population for a new synthetic stock, called an "artificial center of origin" (ACO). Four genomic maps were created using microsatellite and AFLP markers, two from a 3WC family [Om female and (Oa x ROn) male] and two from a 4WC family [(Om x Oas) females and (Sg x On) male]. Sixty-two loci segregating from the female parent of the 3WC mapped to 14 linkage groups while 214 loci from the male parent mapped to 24 linkage groups. Similarly, 131 loci segregating from the female parent of the 4WC mapped to 26 linkage groups and 118 loci from the male parent mapped to 25 linkage groups. Preliminary screening of an F2 and a 4WC family identified a number of loci associated with cold tolerance and body weight. These loci were clustered in a few linkage groups, suggesting they may be indicative of quantitative trait loci.

Abstract:
More than 15,000 anthers of an interspecific hybrid (CP2) between two diploid (2n=2x=24) potato species, Solanum chacoense (weedy) and S. phureja (cultivated), were cultured to generate a family of monoploid (haploid, 2n-1x=12) plants. Of 260 regenerated plants, 34 were monoploid, 210 diploid and 16 tetraploid. SSR analysis revealed that six monoploids were genetically identical and 14 diploids were homozygous, thus limiting the population to 42 (28 monoploids and 14 homozygous diploids). New microsatellite loci were developed for potato from database sequences (15), a conventional genomic library (6), an enriched library (18) and tomato (11). Of these, 13 were polymorphic in the CP2 family and 11 were used to study genetic segregatin. Four of 11 exhibited skewed segregation in the monoploid family. Seven of 18 microsatellite markers were polymorphic and informative on a set of 12 tetraploid potato cultivars. Acetylleptinidine (ALD) is the aglycone of leptines, a natural defense against insects, especially the highly destructuve Colorado potato beetle. ALD is absend in S. phureja but highly expressed in the S. chacoense parent of CP2. A backcross population between CP2 and tis S. phureja parent was used to examine segregation for ALD. Bulks of 10 backcross individuals that expressed ALD and 10 that did not were used to identify putative RAPD markers associatd with the trait. Of 80 primers tested, one putative marker amplified by OPQ02 was present in eight of ten individuals comprising the high bulk and absent in all 10 individuals comprising the low bulk. This is a putative marker for ALD expression in potato.

Abstract:
The objective was to screen maize lines for their ability to express resistance based on biochemical traits. Cultivars were screened for retention of the hydroxamic acid DIMBOA and the synthesis of phenols (based on anthocyanin production) as markers for resistance. Lines were selected and inoculated with fungal pathogens (Exserohilum turcicum, Puccinia sorghi, Cochliobolus heterostraphus, Colletotricum graminicola.), and the Maize Dwarf Mosaic and Johnson Grass Mosaic viruses. Lines were screened in the field and greenhouse. Results showed that lines selected for augmented phenol synthesis do exhibit heightened levels of resistance to fungal pathogens. Isolation of mRNA followed by northern analyses for expression of A1 (dihydroflavanol reductase) and peroxidase confirmed that genes for these enzymes were turned on in response to inoculation of lines predicted to exhibit resistance. Peroxidase and b-1,3-glucanase were assayed in breeding lines having or lacking the se gene. A specific ionically-bound peroxidase isozyme and a b-1,3-glucanase isozyme were revealed in lines having the se gene. Data suggest that peroxidase and b-1,3-glucanase isozymes, may be considered as markers to identify resistance to E. turcicum in maize genotypes with the se gene.

Full text
Abstract:
Plant species synthesize a multitude of specialized compounds 10 help ward off pests. and these in turn may well serve as an alternative to synthetic pesticides to reduce environmental damage and health risks to humans. The general goal of this research was to perform a genetic and biochemical dissection of the natural-insecticides methylketone pathway that is specific to the glandular trichomes of the wild species of tomato, Solanumhabrochaites f. glabratum (accession PI126449). Previous study conducted by us have demonstrated that these compounds are synthesized de novo as a derivate pathway of the fatty acid biosynthesis, and that a key enzyme. designated MethylketoneSynthase 1 (MKS 1). catalyzes conversion of the intermediate B-ketoacyl- ACPs to the corresponding Cn-1 methylketones. The approach taken in this proposed project was to use an interspecific F2 population. derived from the cross between the cultivated lV182 and the wild species PIl26449. for three objectives: (i) Analyze the association between allelic status of candidate genes from the fatty acid biosynthesis pathway with the methylketone content in the leaves (ii) Perform bulk segregant analysis of genetic markers along the tomato genome for identifying genomic regions that harbor QTLs for 2TD content (iii) Apply differential gene expression analysis using the isolated glands of bulk segregant for identifying new genes that are involved in the pathway. The genetic mapping in the interspecific F2 population included app. 60 genetic markers, including the candidate genes from the FAS pathway and SSR markers spread evenly across the genome. This initial; screening identified 5 loci associated with MK content including the candidate genes MKS1, ACC and MaCoA:ACP trans. Interesting observation in this genetic analysis was the connection between shape and content of the glands, i.e. the globularity of the four cells, typical to the wild species. was associated with increased MK in the segregating population. In the next step of the research transcriptomic analysis of trichomes from high- and 10w-MK plants was conducted. This analysis identified a new gene, Methy1ketone synthase 2 (MKS2), whose protein product share sequence similarity to the thioesterase super family of hot-dog enzymes. Genetic analysis in the segregating population confirmed its association with MK content, as well as its overexpression in E. coli that led to formation of MK in the media. There are several conclusions drawn from this research project: (i) the genetic control of MK accumulation in the trichomes is composed of biochemical components in the FAS pathway and its vicinity (MKS 1 and MKS2). as well as genetic factors that mediate the morphology of these specialized cells. (ii) the biochemical pathway is now realized different from what was hypothesized before with MKS2 working upstream to I\1KS 1 and serves as the interface between primary (fatty acids) and secondary (MK) metabolism. We are currently testing the possible physical interactions between these two proteins in vitro after the genetic analysis showed clear epistatic interactions. (iii) the regulation of the pathway that lead to specialized metabolism in the wild species is largely mediated by transcription and one of the achievements of this project is that we were able to isolate and verify the specificity of the MKS1 promoter to the trichomes which allows manipulation of the pathways in these cells (currently in progress). The scientific implications of this research project is the advancement in our knowledge of hitherto unknown biochemical pathway in plants and new leads for studying a new family in plants (hot dog thioesterase). The agricultural and biotechnological implication are : (i) generation of new genetic markers that could assist in importing this pathway to cultivated tomato hence enhancing its natural resistance to insecticides, (ii) the discovery of MKS2 adds a new gene for genetic engineering of plants for making new fatty acid derived compounds. This could be assisted with the use of the isolated and verified MKS1 promoter. The results of this research were summarized to a manuscript that was published in Plant Physiology (cover paper). to a chapter in a proceeding book. and one patent was submitted in the US.

Full text
Abstract:
Although raised pavement markers (RPMs) have been widely applied by the Indiana Department of Transportation (INDOT), there have been multiple cases where snowplowing activities have damaged pavements as well as the raised pavement markers on INDOT’s roadway assets. Dislodged raised pavement markers could reduce the design life of pavements because they leave openings for water and debris to infiltrate through pavement section. Interviews with INDOT personnel indicated that the proper installation of the markers and careful attention to the tooling of the center line of the concrete pavements could alleviate this problem. To explore issues related to the proper installation of RPMs, this study (INDOT/JTRP SPR 4318) was launched by the Indiana Department of Transportation (INDOT)/Joint Transportation Program (JTRP) to develop a synthesis of current practices on installation and maintenance of raised pavement markers at State Transportation Agencies (STAs) in the U.S. The study was conducted using a qualitative exploratory approach focusing on the review of current practices in installation and maintenance of raised pavement markers among STAs. Survey analysis and focused interviews with personnel from STAs, along with reviews of documents provided by STAs were the avenues used for data collection in this project.

It will not be possible to transform the Swiss electricity system with technological solutions alone. The shaping of market conditions and regulations will be at least as important. These market conditions and regulations need to guide economic resources in the right direction through the provision of incentives and possible solutions. And it is here that action needs to be taken.
