Abstract:

Soft errors are a serious concern in state holders as it can cause temporarily malfunction of the circuit. C-element is one of the state holders that is used widely in the asynchronous circuit. In this paper, the investigation will focus on the vulnerability of two types of C-element towards soft errors. A framework has been proposed for the rate of error due to neutron spectrum energy that can cause failure in the state holder. Effective analysis has been conducted on two different C-elements at different nodes by using UMC90 nm technology and 180nm technology. Based on the vulnerability data, a method for assessing vulnerability on a different implementation of C-elements has been developed. From the obtained data, it can be concluded that SIL is more resistant towards soft errors.

Abstract:

Chromosome regions which carry potential QTLs for high grain yield in two synthetic maize populations - B73xMol7 and LlxMol7, were identified by bulk segregant analysis (BSA). Yield was evaluated on F2 testcross families in field trials using a Nested design. Based on yield data, p3 families with the corresponding highest and lowest testcross yields were selected for BSA. Genome analysis of F3 families was carried out with 58 RFLP markers. Allele frequency differences were detected at four RFLP loci n chromosomes 1, 2, 6 and 10 (B73xMol7), i.e. four RFLP loci on chromosomes 1, 2, 6 and 9 (LlxMo17). Only one region, at chromosome 6, was identified in both populations, but with two different RFLP markers. In B73xMol7 it was umc65 and in LlxMol7 umc2l RFLP marker. Bulk segregant analysis was shown to be a quick and informative method for identification of chromosome regions which determine high yield expression in maize, i.e. for identification of RFLP markers closely linked to potential genes involved in expression of the trait.

Abstract:

The recessive gene rhm confers chlorotic-lesion resistance to Bipolaris maydis race O, the southern corn leaf blight pathogen, in otherwise susceptible maize plants. Because of inconsistencies encountered in scoring the disease on mature plants in the field, an assay was developed to monitor the expression of this gene in maize seedlings under controlled conditions. One hundred and two related F3 families from the cross RH95rhm × B73 were inoculated with conidia of B. maydis race O, and the genotype at the rhm locus of each F2 parent was deduced from the reactions observed in the progeny seedlings. The F2 genomes were reconstituted by extracting DNA from leaf tissue pooled from 30–36 F3 progeny plants per family. The seedling disease ratings were analyzed together with the segregation scores for 14 single-copy DNA probes. Our results indicate that rhm is tightly linked to two restriction fragment length polymorphism (RFLP) marker loci (UMC85 and p144) that map to the short arm of chromosome 6. In addition, a rapid assay based on the polymerase chain reaction was used to confirm the linkage between rhm and the p144 RFLP marker locus in a second unrelated F2 population.Key words: Zea mays L., RFLP, disease resistance gene, southern corn leaf blight, genetic linkage mapping.

Abstract:

Abstract C-glycosyl flavones in maize silks confer resistance (i.e., antibiosis) to corn earworm (Helicoverpa zea [Boddie]) larvae and are distinguished by their B-ring substitutions, with maysin and apimaysin being the di- and monohydroxy B-ring forms, respectively. Herein, we examine the genetic mechanisms underlying the synthesis of maysin and apimaysin and the corresponding effects on corn earworm larval growth. Using an F2 population, we found a quantitative trait locus (QTL), rem1, which accounted for 55.3% of the phenotypic variance for maysin, and a QTL, pr1, which explained 64.7% of the phenotypic variance for apimaysin. The maysin QTL did not affect apimaysin synthesis, and the apimaysin QTL did not affect maysin synthesis, suggesting that the synthesis of these closely related compounds occurs independently. The two QTLs, rem1 and pr1, were involved in a significant epistatic interaction for total flavones, suggesting that a ceiling exists governing the total possible amount of C-glycosyl flavone. The maysin and apimaysin QTLs were significant QTLs for corn earworm antibiosis, accounting for 14.1% (rem1) and 14.7% (pr1) of the phenotypic variation. An additional QTL, represented by umc85 on the short arm of chromosome 6, affected antibiosis (R2 = 15.2%), but did not affect the synthesis of the C-glycosyl flavones.

Abstract:

Previously, Mdm1, a gene controlling resistance to Maize dwarf mosaic virus (MDMV), was identified in the inbred line Pa405. The gene was tightly linked to the restriction fragment length polymorphism marker umc85 on the short arm of chromosome 6. This chromosomal region is also the location of resistance genes to two other viruses in the family Potyviridae, Sugarcane mosaic virus (SCMV) and Wheat streak mosaic virus (WSMV). A diverse collection of 115 maize inbred lines was evaluated for resistance to MDMV and SCMV, and for MDMV resistance loci on chromosome 6S. Forty-six resistant inbred lines were crossed to three MDMVsusceptible inbred lines to develop F2 populations. The F2 populations were inoculated with MDMV and scored for infection and symptom type. Environmental factors influenced both the rate and type of symptom development. Bulked segregant analysis of each F2 population indicated that, in 42 of 43 MDMV-resistant lines, chromosome 6S markers found in the resistant parent also were present in the bulked resistant but not the susceptible tissue. Markers previously associated with resistance to both SCMV and WSMV on chromosome 3 and to WSMV on chromosome 10 were associated with resistance in nine and seven of the F2 populations, respectively. These data suggest that Mdm1 or closely linked genes on chromosome 6S are associated with MDMV resistance in most germplasm, but that other loci also may affect resistance.

Abstract:

This study was conducted to identify the chromosomal location and magnitude of effect of quantitative trait loci (QTL) controlling sweet corn (Zea mays L.) stand establishment and investigate the impact of dry kernel characteristics on seedling emergence under field conditions. Genetic and chemical analysis was performed on two F2:3 populations (one homozygous for su1 and segregating for se1, the other homozygous for sh2 endosperm carbohydrate mutations) derived from crosses between parental inbreds that differed in field emergence and kernel chemical composition. A series of restriction fragment-length polymorphism (RFLP) and phenotypic markers distributed throughout the sweet corn genome were used to construct a genetic linkage map for each population. F2:3 families from the two populations were evaluated for seedling emergence and growth rate at four locations. Mature dry kernels of each family were assayed for kernel chemical and physiological parameters. Composite interval analysis revealed significant QTL associations with emergence and kernel chemical and physiological variables. Improved emergence was positively correlated with lower seed leachate conductivity, greater embryo dry weight, and higher kernel starch content. QTL affecting both field emergence and kernel characteristics were detected in both populations. In the su1 se1 population genomic regions significantly influencing emergence across all four environments were found associated with the se1 gene on chromosome 2 and the RFLP loci php200020 on chromosome 7 and umc160 on chromosome 8. In the sh2 population the RFLP loci umc131 on chromosome 2 and bnl9.08 on chromosome 8 were linked to QTL significantly affecting emergence. Since seedling emergence and kernel sugar content have been shown to be negatively correlated, undesirable effects on sweet corn eating quality associated with each emergence QTL is discussed. Segregating QTL linked to RFLP loci in these populations that exert significant effects on the studied traits are candidates for molecular marker-assisted selection to improve sweet corn seed quality.

Abstract:

Association analysis or linkage disequilibrium mapping is a method for identification of quantitative trait loci (QTLs) in a panel of divergent unrelated individuals based on historical recombinations during a crop?s domestication and selection. It should account for the population structure, which can be the result of adaptation to local conditions or selection, to reduce the possibility of declaring false-positive associations. The aim of this study was to determine potentially significant and consistent associations between markers and agronomic important maize (Zea mays L.) traits using association analysis in a diverse breeding material that can be ultimately implemented in maize selection. To this end, 96 maize inbred lines were evaluated in field trials at three locations in Serbia for eleven agronomic traits and analysed with microsatellite markers. Twenty five microsatellites were used to assess the population structure using Bayesian model-based clustering method and to test the significance of associations between the markers and the traits with general (GLM) and mixed linear (MLM) models. The cluster analysis divided maize inbred lines in four subpopulations, corresponding to the BSSS (Iowa Stiff Stalk Synthetic), LSC (Lancaster Sure Crop), Iodent heterotic groups and exotic and independent germplasm. The models identified associations between twenty five microsatellite markers and eleven agronomic traits, resulting in 133 and 71 associations across the environments for GLM and MLM, respectively. Some of the identified marker-trait associations were significant and consistent in several environments. The associations stable in several environments were identified between the markers bnlg1067 and two flowering traits; nc005 and bnlg434 and plant height, bnlg434 and ear height; bnlg1643 and umc1127 and leaf number, bnlg1360 and ear diameter; umc1019 and umc1506 and number of rows per ear; bnlg2305 and bnlg1451 and ear length, and between bnlg1175 and thousand-kernel weight. The results of this study indicate that these microsatellites could be used in marker-assisted selection of inbred lines, after validation of the marker-trait associations and testing combining abilities of the inbreds during hybrid development.

Abstract:

A study was conducted to determine the number and chromosomal location of quantitative trait loci (QTL) influencing the concentration of five fatty acids in 200 F2S1 lines derived from an Illinois High Oil (IHO) by Illinois Low Oil (Early Maturity) (ILO(EM)) cross. Restriction fragment length polymorphism (RFLP) analysis was performed on the 200 S1 lines and concentrations of palmitic (16:0), stearic (18:0), oleic (18:1), linoleic (18:2), and linolenic (18:3) acids were determined in self-pollinated kernels harvested from plants grown in replicated field trials during 1992 and 1993. A series of 74 cDNA and genomic clones were used and these revealed 80 polymorphic loci spaced, on average, 24 cM apart throughout the maize genome. Analysis of variance detected significant (p < 0.05) associations between several RFLP loci and the concentration of each fatty acid. A total of 15 RFLP loci clustered in 12 chromosomal regions were associated with the concentration of 16:0, 17 loci clustered in 10 regions were associated with the concentration of 18:0, 12 loci clustered in eight regions were associated with the concentration of 18:1 and 18:2, and 17 loci clustered in eight regions were associated with the concentration of 18:3. Multiple linear regression models consisting of four RFLP loci explained 24 and 62% of the total phenotypic and genotypic variation (R2) among the 200 F2S1 lines for 16:0, five loci explained 51 and 71% of the variation for 18:0, three loci explained 67 and 79% of the variation for 18:1, two loci explained 67 and 81% of the variation for 18:2, and seven loci explained 52 and 78% of the variation for 18:3 in these 200 F2S1 lines. The ratio of 18:1 to 18:2 was tightly interrelated as the same QTL were associated with the concentrations of 18:1 and 18:2. A quantitative trait locus that explained 63% of the phenotypic variation in the ratio of 18:1 to 18:2 is tightly linked to umc65 on chromosome 6 in the region of the linoleic acid1 locus.Key words: maize, fatty acid, oleic, linoleic, RFLP, QTL.

Abstract:

In order to meet the housing need that emerged in Turkey after the devastating earthquake of 17th August 1999, new residential areas were established in various regions. This has led to the questioning of how social sustainability of new settlements can be achieved and to a search for solutions. In this context, participatory approaches are among the first to come to mind. This study starts from the hypothesis that enabling user participation in the construction process of the housing units would contribute to the social cohesion and satisfaction levels of the neighborhood in question. In the study, the impact of user participation on the social sustainability of the construction process of residential projects developed following a disaster has been tested. In this context, the research was conducted in Caritas houses built near Gümüşpınar Village in the Province of Düzce and Umcor houses constructed on the same land with user participation to meet the needs of the victims for shelter after the 17th August 1999 earthquake. The study is comprised of the observations, questionnaires and face-to-face interviews conducted after the literature review. Questionnaires and interviews were conducted to measure the satisfaction with the housing, the immediate housing environment and the neighborhood as well as the feeling of belonging were tested regarding the two settlements which differed in terms of their construction methods and physical characteristics despite having been constructed side by side by two different charities. The results of the Likert type questionnaires were evaluated with the “Independent samples T test” using the SPSS program. As a result of the research, it has been found that there is no significant relationship between user participation and the criteria of social sustainability; namely, satisfaction with the housing, satisfaction with the neighbors and that of the residence neighborhood. Another result of the research is that the physical and psychological comfort is of priority for the individuals compared to relationship with neighbors or participation in the establishment of their residential environment. Furthermore, the research findings also revealed that disagreements among users increased which had a negative impact on social cohesion in cases where the physical characteristics of the residential neighborhood and the housing did not satisfy the users.

Abstract:

This paper shows a structure of current starved inverter-based CMOS thyristor oscillator which is utilized to drive the counters that go about as a segment in the elapsed time counter. The performance of this oscillator is improved using a temperature independent biasing circuit that utilizes low power. The design incorporates utilization of trim bits at different process corners to shift the frequency. As the oscillator works with a battery supply, the output variations across supply are compromised. On – chip oscillator is implemented in a silicon area of 0.003064 mm² using UMC180 CMOS technology. Output shows a low power low frequency performance compared to a regular on- chip oscillator.
