Abstract:

Begomoviruses occur in many plant species in Pakistan and are associated with an epidemic of cotton leaf curl disease that has developed since 1985. PCR analysis with primer pairs specific for each of four already sequenced types of DNA-A of cotton leaf curl virus (CLCuV-PK types a, 26, 72b and 804a), or for okra yellow vein mosaic virus (OYVMV), indicated that many individual naturally infected plants of cotton and other malvaceous species contained two or three begomovirus sequences. Similarly, sequence differences among overlapping fragments of begomovirus DNA-A, amplified from individual naturally infected plants, indicated much multiple infection in malvaceous and non-malvaceous species. Some cotton plants contained DNA-A sequences typical of begomoviruses from non-malvaceous species, and some non-malvaceous plants contained sequences typical of CLCuV-PK. Some DNA-A sequences were chimaeric; they each included elements typical of different types of CLCuV-PK, or of different malvaceous and/or non-malvaceous begomoviruses. Often an apparent recombination site occurred at the origin of replication. No complete CLCuV-PK DNA-A sequence was found in malvaceous or non-malvaceous species collected in Pakistan outside the area of the cotton leaf curl epidemic but chimaeric sequences, including a part that was typical of CLCuV-PK DNA-A, did occur there. We suggest that recombination among such pre-existing sequences was crucial for the emergence of CLCuV-PK. Recombination, following multiple infection, could also explain the network of relationships among many of the begomoviruses found in the Indian subcontinent, and their evolutionary divergence, as a group, from begomoviruses causing similar diseases in other geographical regions.

Full text

Abstract:

A review of key publications concerning the biology and life cycles of microsporidians has led us to challenge recent proposals that they exhibit a unique process of meiosis when compared with other eukaryotes. The basic data used to support this challenge are the same as those used by researchers suggesting atypical meiosis, but the data are analyzed from a different viewpoint. Arguments are put forward to support a testable hypothesis that meiosis in microsporidians is identical to that which occurs in other eukaryotes. It is proposed that confusion resulted because two separate cytological developmental sequences for diplokaryotic meronts in mosquito fat body cells were previously interpreted as a single sequence. By rearrangement of the original data into two developmental sequences, one abortive and the other for typical meiosis, a better fit was obtained between cytological stages and microphotometric measurements of nuclear DNA content. This improved data fit and the existence of similar nuclear developmental sequences in the fungi are used to support our hypothesis.Key words: microsporidia, meiosis, eukaryotes.

Abstract:

In cognitive radio (CR) cooperative sensing schemes, wireless sensor nodes deployed in the network sense the licensed spectrum and send their local sensing decisions to a fusion center (FC) that makes a global decision on whether to allow the unlicensed user transmit on the licensed spectrum, based on a decision (fusion) rule. k-out-of-N is widely used in the literature owing to its practical simplicity. Regrettably, it exhibits a tradeoff between the achievable probabilities of false alarm and miss detection, which could have consequent effects on the performance of CR. In this paper, based on the notion of typical sequences, we propose a novel fusion rule in which the false alarm and miss detection probabilities can be simultaneously made as small as desired (asymptotically zero as the number of sensors goes to infinity).

Abstract:

The typical Tauberian theorem asserts that a particular summability method cannot map any divergent member of a given set of sequences into a convergent sequence. These sets of sequences are typically defined by an order growth or gap condition. We establish that any conull space contains a bounded divergent member of such a set; hence, such sets fail to generate Tauberian theorems for conull spaces.

Abstract:

A new paradigm, the “teaching-by-examples” paradigm, was used to shed new light on the process of category acquisition. In four experiments ( n = 90, 90, 115, 117), manipulating the variables of category structure, status of non-target category, learning mode, and teaching mode, participants first learned a category and then taught it to someone else. High agreement between participants on the teaching sequences was found across conditions, and a typical sequence was identified for each category structure. The typical participant-produced sequences started with several ideal positive cases, followed by an ideal negative case and then borderline cases. The efficiency of such sequences for teaching was tested in another experiment ( n = 60), in which they were compared with sequences emphasizing category borders and sequences emphasizing each dimension separately. The typical participant-produced sequences induced the most efficient learning. It is proposed that the pattern of performance may provide a rich source of data for testing and fine-tuning models of category acquisition.

Abstract:

A problem of social sequences of lung tuberculosis has not been reflected in the literature. This study was aimed to investigate social sequences of tuberculosis. We examined a continuous sample of 100 patients with lung tuberculosis (LT) while being treated in a hospital, of them 62 males and 38 females aged 22 to 56 yrs. Fifty patients had infiltrative LT, and other 50 ones had fibrocavitating LT. The diagnosis was reached based on typical clinical, radiological, laboratory, and functional investigations. A special questionnaire was developed to study social sequences of LT. Results showed social isolation is typical for both the newly diagnosed LT patients and chronic LT. The fibrocavitating LT patients experienced negative attitude of relatives and community, worsening working conditions and narrowing fields of interest. The infiltrative LT patients were characterized by changes in marital status and disorders of living plans. Therefore, all LT patients experience social sequences of the disease.

Abstract:

ABSTRACT A promoterless lacZ shuttle vector, which allowed screening of promoters by β-galactosidase activity inCampylobacter jejuni and Escherichia coli, was developed. Chromosomal DNA fragments from C. jejuniwere cloned into this vector; 125 of 1,824 clones displayed promoter activity in C. jejuni. Eleven clones with strong promoter activity in C. jejuni were further characterized. Their nucleotide sequences were determined, and the transcriptional start sites of the putative promoters in C. jejuni were determined by primer extension. Only 6 of these 11 promoters were functional in E. coli. The 11 newly characterized and 10 previously characterized C. jejuni promoters were used to establish a consensus sequence for C. jejuni promoters. The 21 promoters were found to be very similar. They contain three conserved regions, located approximately 10, 16, and 35 bp upstream of the transcriptional start point. The −10 region resembles that of a typical ς70 E. colipromoter, but the −35 region is completely different. In addition a −16 region typical for gram-positive bacteria was identified.

Abstract:

In the context of all-digital radar systems, phase-modulated continuous wave (PMCW) based on pseudorandom binary sequences (PRBSs) appears to be a prominent candidate modulation scheme for applications such as autonomous driving. Among the reasons for its candidacy are its simplified transmitter architecture and lower linearity requirements (e.g., compared to orthogonal-frequency division multiplexing radars), as well as its high velocity unambiguity and multiple-input multiple-output operation capability, all of which are characteristic of digital radars. For appropriate operation of a PMCW radar, choosing a PRBS whose periodic autocorrelation function (PACF) has low sidelobes and high robustness to Doppler shifts is paramount. In this sense, this article performs an analysis of Doppler shift tolerance of the PACFs of typically adopted PRBSs in PMCW radar systems supported by simulation and measurement results. To accurately measure the Doppler-shift-induced degradation of PACFs, peak power loss ratio (PPLR), peak sidelobe level ratio (PSLR), and integrated-sidelobe level ratio (ISLR) were used as metrics. Furthermore, to account for effects on targets whose ranges are not multiples of the range resolution, oversampled PACFs are analyzed.

Abstract This paper extends the computationally-oriented theory of ellipsis presented in McShane’s A Theory of Ellipsis (2005) by introducing the feature typical event sequence. It is argued that, in Russian, the presence of a typical sequence of events in a pair of clauses can be the key feature licensing the ellipsis of the latter’s direct object. The linguistic analysis contributes to a larger cognitive modeling effort aimed at configuring language-endowed intelligent agents with human-level language understanding capabilities.

Abstract:

In the present work we describe preliminary results on a partial VvMybA1 locus sequencing of rear indigenous grapevine varieties. Obtained sequences were mostly conservative and have matches in NCBI GenBank. As expected, most of them have a sequence that is typical for varieties with non-colored berries. Surprisingly, however, cultivar Jaj izium biely demonstrated structure typical for varieties with colored berries, which implies another reason for the loss of color. Obviously, Tavlinskii pozdnii and Sypun chernyj varieties had typical for colored cultivars allele structure. Some nucleotide substitutions and differences in structure of sequences were found. Furthemore, we submitted our sequences to the NCBI and here we present their accession numbers: Unji bely (MW633123), Voskeat (MW633125), Tsolikauri (MW633126), Shabash (MW633127), Terbash (MW633130), Bajan Shirei (MW633131), Katta Kurgan (MW633132), Sirgula (MW633135), Khatmi (MW633136), Jaj izium biely (N/A), Tavlinskii pozdnii (MW633139), Sypun chernyj (MW633151). All sequences, excluding Jaj izium biely genotype, were submitted to the GenBank and will be available to the public as soon as possible.

Abstract:

Three dictyostelid isolates were found in Spain and Argentina that are morphologically different from known species. These isolates have some features similar to Dictyostelium sphaerocephalum (Oudem.) Sacc., Marchal & É.J. Marchal, but differ in size and sorocarp branching pattern. We sequenced the nuclear ribosomal internal transcribed spacer region to explore phylogenetic relationships among this group of species, including the three new isolates and their closest relatives. In all phylogenetic analyses performed, sequences of all three isolates group together with sequences from “typical” D. sphaerocephalum samples. This result supports previous observations of the morphological plasticity in dictyostelids, especially D. sphaerocephalum, leading us to broaden the classical concept of this species.

Abstract:

AbstractWe obtain a nontrivial upper bound for almost all elements of the sequences of real numbers which are multiplicative and at the prime indices are distributed according to the Sato–Tate density. Examples of such sequences come from coefficients of severalL-functions of elliptic curves and modular forms. In particular, we show that |τ(n)| ⩽n11/2(logn)−1/2+o(1)for a set ofnof asymptotic density 1, where τ(n) is the Ramanujan τ function while the standard argument yields log 2 instead of −1/2 in the power of the logarithm. Another consequence of our result is that in the number of representations ofnby a binary quadratic form one has slightly more than square-root cancellations for almost all integersn.In addition, we obtain a central limit theorem for such sequences, assuming a weak hypothesis on the rate of convergence to the Sato–Tate law. For Fourier coefficients of primitive holomorphic cusp forms such a hypothesis is known conditionally and might be within reach unconditionally using the currently established potential automorphy.

Abstract:

Protein sequences are typical complex systems and the knowledge of their local features is very important to predict their secondary structures and biological function. In the present paper a compositional complexity is used to measure the local features of the protein sequences. We found that the transition segments between the regular secondary structures (α-helices and β-strands) and irregular secondary structures (loops and turns) usually have higher complexity than the neighboring segments. This result may be useful to identify the locations of irregular secondary structures which usually are active sites.

Full text

Abstract:

Non-coding segments of the human genome are enriched in cis-regulatory modules that constitute functional elements, such as transcriptional enhancers and Super-enhancers. A hallmark of cancer pathogenesis is the dramatic dysregulation of the “archetype” gene expression profiles of normal human cells. Genomic variations can promote such deficiencies when occurring across enhancers and Super-enhancers, since they affect their mechanistic principles, their functional capacity and specificity, and the epigenomic features of the chromatin microenvironment across which these regulatory elements reside. Here, we comprehensively describe: fundamental mechanisms of gene expression dysregulation in cancers that involve genomic abnormalities within enhancers’ and Super-enhancers’ (SEs) sequences, which alter the expression of oncogenic transcription factors (TFs); cutting-edge technologies applied for the analysis of variation-enriched hotspots of the cancer genome; and pharmacological approaches for the treatment of Super-enhancers’ aberrant function. Finally, we provide an intratumor meta-analysis, which highlights that genomic variations in transcription-factor-driven tumors are accompanied overexpression of genes, a portion of which encodes for additional cancer-related transcription factors.

Abstract:

The 16, 299 bp long mitochondrial genome (mitogenome) of a tessaratomid bug, Eusthenes cupreus (Westwood), is reported and analyzed. The mitogenome represents the first sequenced complete mitogenome of the heteropteran family Tessaratomidae. The mitogenome of E. cuopreus is a typical circular DNA molecule with a total AT content of 74.1%, and contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a control region. The gene arrangement is identical with the most common type in insects. Most PCGs start with the typical ATN codon, except that the initiation codon for COI is TTG. All tRNAs possess the typical clover-leaf structure, except tRNASer (AGN), in which the dihydrouridine (DHU) arm forms a simple loop. Six domains with 45 helices and three domains with 27 helices are predicted in the secondary structures of rrnL and rrnS, respectively. The control region is located between rrnS and tRNAIle, including some short microsatellite repeat sequences. In addition, three different repetitive sequences are found in the control region and the tRNAIle-tRNAGln-tRNAMet-ND2 gene cluster. One of the unusual features of this mitogenome is the presence of one tRNAGln-like sequence in the control region. This extra tRNAGln-like sequence is 73 bp long, and the anticodon arm is identical to that of the regular tRNAGln.

Full text

Abstract:

The present study utilizes a corpus-driven approach to identify the most common multi-word patterns in conversation and academic writing, and to investigate the differing pattern types in the two registers. The paper first surveys the methodological characteristics of corpus-driven research and then contrasts the linguistic characteristics of two types of multi-word sequences: ‘multi-word lexical collocations’ (combinations of content words) versus ‘multi-word formulaic sequences’ (incorporating both function words and content words). Building on this background, the primary focus of the paper is an empirical investigation of the ‘patterns’ represented by multi-word formulaic sequences. It turns out that the multi-word patterns typical of speech are fundamentally different from those typical of academic writing: patterns in conversation tend to be fixed sequences (including both function words and content words). In contrast, most patterns in academic writing are formulaic frames consisting of invariable function words with an intervening variable slot that is filled by content words.

The quantification of boron neutron capture therapy (BNCT)10B‒carrier, L‒p‒boronophenylalanine‒fructose complex (BPA–F) was studied with phantoms using1H magnetic resonance spectroscopy sequences PRESS and STEAM at 1.5 and 3.0 T. The results show that typical attainable short echo times of clinical MRS sequences combined with long repetition time result in clinically acceptable quantification accuracy. However, the concentration ratios, which are essential for the treatment planning, can still be reliably measured by using small repetition times. Detection limits of BPA in aqueous phantoms at 1.5 and 3.0 T were evaluated using clinically acceptable measurement time of ~10 min, two typical voxel sizes (153and 203mm3) and PRESS and STEAM sequences. The detection limits of BPA in phantom conditions were 0.7 (3.0 T) and 1.4 mM (1.5 T) for PRESS sequence with 203mm3voxel.

Abstract Twenty-six cabbage heads stored under typical conditions in a storage hall in Moravia, Czech Republic, were tested for the presence of bacteria by the method of isolation from three different parts of the cabbage heads. Isolations were carried out from stalks, inner and superficial leaves. Two samplings were done; in November 2015 and February 2016. Bacterial cultures were sequenced in the part of 16S rRNA region; bacteria were identified according to the sequences obtained. The most prevalent bacteria were of the genus Pseudomonas. Genera: Klebsiella, Erwinia, Pantoea, Bacillus were also identified. The results provided an interesting insight into the bacterial spectrum in stored cabbage heads and their dynamics during storage. The nucleotide sequences which were found were saved in GenBank/NCBI under accession numbers KX160104-KX160145.

Abstract:

AbstractWe recently discovered that NGC 3201 has characteristics that set it outside the current twofold classification scheme for Galactic globular clusters (GCs). Most GCs are mono-metallic and show light-element abundance variations (e.g., Na-O and C-N anti-correlations); but a minority of clusters also present variations in Fe correlating with s-process element and C+N+O abundances, and they possess multiple C-N sequences. These anomalous GCs also have a broad sub-giant branch (SGB) and follow the same mass-size relation as dwarf galaxies possibly evolving into GCs. We now revealed that NGC 3201 belongs to neither group. It has multiple C-N sequences, but no broad SGB, no strong evidence of a Fe-spread, and it does not follow the mass-size relation.

Abstract:

In this paper, the typical two-dimensional Henon map is studied. Firstly, the model of Henon map is proposed based on DSP Builder platform in Simulink library, so it can generate digital output sequence of Henon map. Then, its statistical properties are analyzed for such output sequences, including balance test, run test and autocorrelation test. Finally, the numerical results show that such digital Henon sequences have good pseudo-randomness.

Abstract:

Purpose The purpose of this study was to examine the influence of phonotactic probability on sublexical (phonological) and lexical representations in 3-year-olds who had a history of being late talkers in comparison with their peers with typical language development. Method Ten 3-year-olds who were late talkers and 10 age-matched typically developing controls completed nonword repetition and fast mapping tasks; stimuli for both experimental procedures differed in phonotactic probability. Results Both participant groups repeated nonwords containing high phonotactic probability sequences more accurately than nonwords containing low phonotactic probability sequences. Participants with typical language showed an early advantage for fast mapping high phonotactic probability words; children who were late talkers required more exposures to the novel words to show the same advantage for fast mapping high phonotactic probability words. Conclusions Children who were late talkers showed similar sensitivities to phonotactic probability in nonword repetition and word learning when compared with their peers with no history of language delay. However, word learning in children who were late talkers appeared to be slower when compared with their peers.

Abstract In 1964 K. F. Roth initiated the study of irregularities of distribution of binary sequences relative to arithmetic progressions and since that numerous papers have been written on this subject. In the applications one needs binary sequences which are well distributed relative to arithmetic progressions, in particular, in cryptography one needs binary sequences whose short subsequences are also well-distributed relative to arithmetic progressions. Thus we introduce weighted measures of pseudorandomness of binary sequences to study this property. We study the typical and minimal values of this measure for binary sequences of a given length.

Telomeric DNA of human chromosomes plays a significant role in physiological processes such as cell cycle, aging, cancer and genetic stability due to its special sequence and structure. The research on small molecule ligands targeting G-quadruplex formed by such special sequence has attracted considerable attention, and has achieved great breakthrough. In this paper, we summarize the DNA sequences and structures of three kinds of typical human telomeric G-quadruplex, providing an important reference for further research.

Abstract:

Currently, the palaeopteran lineages (insect orders Ephemeroptera and Odonata) that have a problematic relationship with neopteran lineages are poorly represented by mitogenome sequences. In this study, we have determined the complete mitogenome of the oriental mayfly, Ephemera orientalis (Ephemeroptera: Ephemeridae), and the dragonfly Davidius lunatus (Odonata: Gomphidae). The 16 463 bp mitogenome of E. orientalis and the 15 912 bp mitogenome of D. lunatus have many of the features typically detected in insect mitogenomes. Although the initiation codon for the D. lunatus COI gene is the typical ATA, E. orientalis is unusual in that no typical start codon was detected in the start region of the COI gene. The A+T-rich regions of both mitogenomes have some unusual features. The E. orientalis A+T-rich region harbors two identical 55 bp sequences separated by 158 bp, and the D. lunatus A+T-rich region harbors a tandem repeat comprising two identical 261 bp copies and one partial copy of the repeat. Additionally, the A+T-rich regions of both mitogenomes harbor the stem-and-loop structures flanked by the conserved sequences “TA(A)TA” at the 5′ end and “G(A)nT” at the 3′ end, which have been suggested to be the signals involved in minor strand replication initiation. Furthermore, the D. lunatus A+T-rich region contains two tRNA-like structures with proper anticodon and cloverleaf structures.

Abstract:

Abstract Background and Aims Fully mycoheterotrophic plants derive carbon and other nutrients from root-associated fungi and have lost the ability to photosynthesize. While mycoheterotroph plastomes are often degraded compared with green plants, the effect of this unusual symbiosis on mitochondrial genome evolution is unknown. By providing the first complete organelle genome data from Polygalaceae, one of only three eudicot families that developed mycoheterotrophy, we explore how both organellar genomes evolved after loss of photosynthesis. Methods We sequenced and assembled four complete plastid genomes and a mitochondrial genome from species of Polygalaceae, focusing on non-photosynthetic Epirixanthes. We compared these genomes with those of other mycoheterotroph and parasitic plant lineages, and assessed whether organelle genes in Epirixanthes experienced relaxed or intensified selection compared with autotrophic relatives. Key Results Plastomes of two species of Epirixanthes have become substantially degraded compared with that of autotrophic Polygala. Although the lack of photosynthesis is presumably homologous in the genus, the surveyed Epirixanthes species have marked differences in terms of plastome size, structural rearrangements, gene content and substitution rates. Remarkably, both apparently replaced a canonical plastid inverted repeat with large directly repeated sequences. The mitogenome of E. elongata incorporated a considerable number of fossilized plastid genes, by intracellular transfer from an ancestor with a less degraded plastome. Both plastid and mitochondrial genes in E. elongata have increased substitution rates, but the plastid genes of E. pallida do not. Despite this, both species have similar selection patterns operating on plastid housekeeping genes. Conclusions Plastome evolution largely fits with patterns of gene degradation seen in other heterotrophic plants, but includes highly unusual directly duplicated regions. The causes of rate elevation in the sequenced Epirixanthes mitogenome and of rate differences in plastomes of related mycoheterotrophic species are not currently understood.

Abstract:

Abstract Background: Circulating nucleic acids (CNAs) have been shown to have diagnostic utility in human diseases. The aim of this study was to sequence and organize CNAs to document typical profiles of circulating DNA in apparently healthy individuals. Methods: Serum DNA from 51 apparently healthy humans was extracted, amplified, sequenced via pyrosequencing (454 Life Sciences/Roche Diagnostics), and categorized by (a) origin (human vs xenogeneic), (b) functionality (repeats, genes, coding or noncoding), and (c) chromosomal localization. CNA results were compared with genomic DNA controls (n = 4) that were subjected to the identical procedure. Results: We obtained 4.5 × 105 sequences (7.5 × 107 nucleotides), of which 87% were attributable to known database sequences. Of these sequences, 97% were genomic, and 3% were xenogeneic. CNAs and genomic DNA did not differ with respect to sequences attributable to repeats, genes, RNA, and protein-coding DNA sequences. CNA tended to have a higher proportion of short interspersed nuclear element sequences (P = 0.1), of which Alu sequences were significant (P < 0.01). CNAs had a significantly lower proportion of L1 and L2 long interspersed nuclear element sequences (P < 0.01). In addition, hepatitis B virus (HBV) genotype F sequences were found in an individual accidentally evaluated as a healthy control. Conclusions: Comparison of CNAs with genomic DNA suggests that nonspecific DNA release is not the sole origin for CNAs. The CNA profiling of healthy individuals we have described, together with the detailed biometric analysis, provides the basis for future studies of patients with specific diseases. Furthermore, the detection of previously unknown HBV infection suggests the capability of this method to uncover occult infections.

Abstract:

Abstract In his liturgical commentary Rationale divinorum officiorum, the thirteenthcentury writer Guillaume Durand describes a special, “antique” way of singing sequences called “neumatizing” (“neumatizare”). According to Durand, a sequence could be neumatized either by singing certain phrases melismatically or by vocalizing the entire sequence without words. The chief focus of this investigation is the identification of which sequences were still being neumatized after the decline of that practice around 1100, where and at which feasts they were sung, and why. The evidence suggests that neumatizing was especially cultivated in northern France during the twelfth and thirteenth centuries, especially in the cathedral towns of Rouen, Laon, Cambrai, and Amiens, as well as at various religious institutions in Metz, Andenne, Chichester, and Bamberg. The liturgical period of Advent, Christmas Eve, the Feast of John the Evangelist, and masses celebrating patron saints were the most typical liturgical occasions where neumatizing took place. The rationales for the singing practice appear to have been manifold, ranging from the practical and mundane to the spiritual and sacred. Motives for neumatizing include improving preexisting structures for purposes of fulfilling expectations about genre; using musical responses to highlight poetic topoi; lending solemnity and symbolic meaning to important liturgical feasts; and honoring ancient traditions while resisting some of the newer trends found with late examples of the genre.

Abstract:

The red tomato spider mite, Tetranychus evansi Baker & Pritchard, is a newly emerged and globally invasive pest of solanaceous plants. In this study, the complete mitochondrial genome of T. evansi was sequenced using Illumina Hiseq technology. The complete mitochondrial genome of T. evansi is a typical circular DNA with a length of 13,064 bp, which contains 37 genes arranged in consistent with the typical metazoan mitochondrial genomes. Highly truncated mitochondrial tRNAs were observed, with 18 of the 22 tRNAs appearing to lack the D- or T- arms or both. A preliminary phylogenic analysis showed that mitochondrial genome can significantly improve the reliability of phylogenetic inference relative to short sequences, as indicated by the elevated bootstrap values. This mitochondrial genome provides a valuable source for the future phylogenetic analyses and helps clear the introduction origins of the Chinese T. evansi populations.

Abstract:

Dioscorea L., the largest genus of the family Dioscoreaceae with over 600 species, is not only an important food but also a medicinal plant. The identification and classification of Dioscorea L. is a rather difficult task. In this study, we sequenced five Dioscorea chloroplast genomes, and analyzed with four other chloroplast genomes of Dioscorea species from GenBank. The Dioscorea chloroplast genomes displayed the typical quadripartite structure of angiosperms, which consisted of a pair of inverted repeats separated by a large single-copy region, and a small single-copy region. The location and distribution of repeat sequences and microsatellites were determined, and the rapidly evolving chloroplast genome regions (trnK-trnQ, trnS-trnG, trnC-petN, trnE-trnT, petG-trnW-trnP, ndhF, trnL-rpl32, and ycf1) were detected. Phylogenetic relationships of Dioscorea inferred from chloroplast genomes obtained high support even in shortest internodes. Thus, chloroplast genome sequences provide potential molecular markers and genomic resources for phylogeny and species identification.

Abstract:

In this study, the whole mitochondrial genomes of Physogyra lichtensteini and Plerogyra sinuosa have been sequenced for the first time. The length of their assembled mitogenome sequences were 17,286 bp and 17,586 bp, respectively, both including 13 protein-coding genes, two tRNAs, and two rRNAs. Their mitogenomes offered no distinct structure and their gene order were the same as other typical scleractinians. Based on 13 protein-coding genes, a maximum likelihood phylogenetic analysis showed that Physogyra lichtensteini and Plerogyra sinuosa are clustered in the family Plerogyridae, which belongs to the “Robust” clade. The 13 tandem mitogenome PCG sequences used in this research can provide important molecular information to clarify the evolutionary relationships amongst stony corals, especially at the family level. On the other hand, more advanced markers and more species need to be used in the future to confirm the evolutionary relationships of all the scleractinians.

Abstract:

I-states-as-objects-analysis (ISOA) is a person-oriented methodology for studying short-term developmental stability and change in patterns of variable values. ISOA is based on longitudinal data with the same set of variables measured at all measurement occasions. A key concept is the i-state, defined as a person’s pattern of variable values at a specific time point. All i-states are first subjected to a classification analysis that results in a time-invariant classification characterized by a number of typical i-states. Each person is then characterized at each time point by the typical i-state he/she belongs to. Then the person’s sequences of typical i-states are analyzed with regard to structural and individual stability and change. Extensions of ISOA are presented where: (1) some methods for checking the assumption of a time-invariant classification are indicated; (2) information about the degree of dissimilarity between typical i-states is used as an aid in interpreting the findings; and (3) attention is given to closed paths—that is, typical i-state sequences that do not occur at all. To demonstrate the methods, an empirical example is given that concerns the development of children’s achievement-intelligence patterns between ages 10 and 13.
