Most published genome sequences are drafts, and most dominated by computational gene prediction. Draft genomes typically incorporate considerable sequence data that not assigned to chromosomes, predicted genes without quality confidence measures. The current Actinidia chinensis (kiwifruit) 'Hongyang' draft has 164 Mb of unassigned pseudo-chromosomes, omissions have been identified in the models.A second an A. (genotype Red5) was fully sequenced. This new resulted a 554.0 assembly with all...
Recent studies have highlighted an important role of structural variation (SV) in ecological and evolutionary processes, but few studied nonmodel species the wild. As part our long-term research programme on teleost fish Australasian snapper (Chrysophrys auratus), we aim to build one first catalogues genomic variants (SNPs indels, deletions, duplications inversions) fishes evaluate overlap with regions under putative selection (Tajima's D π), coding sequences (genes). For this, analysed six...
Abstract Enormous genomic resources have been developed for plants in the monocot order Poales; however, it is not clear how representative Poales are monocots as a whole. The Asparagales monophyletic sister to lineage carrying and possess economically important such asparagus, garlic, onion. To assess differences between Poales, we generated 11,008 unique ESTs from normalized cDNA library of Sequence analyses these revealed microsatellite markers, single nucleotide polymorphisms, homologs...
Although apomixis has been quoted as a technology with the potential to deliver benefits similar in scale those achieved Green Revolution, very little is currently known of genetic mechanisms that control this trait plants. To address issue, we developed Hieracium, genus daisies native Eurasia and North America, model study apomixis. In molecular mapping study, defined number loci involved apomixis, explored dominance linkage relationships between these loci. avoid difficulties often...
MYB transcription factors play important roles in transcriptional regulation of many secondary metabolites including anthocyanins. We cloned the R2R3-MYB type IbMYB1 complementary DNAs from purple-fleshed sweet potato (Ipomoea batatas L. cv Sinzami) and investigated expression patterns gene with IbMYB1a IbMYB1b splice variants leaf root tissues various cultivars by reverse transcription-polymerase chain reaction. The transcripts were predominantly expressed storage roots they also detectable...

Angiosperm sex chromosomes, where present, are generally recently evolved. The key step in initiating the development of chromosomes from autosomes is establishment a sex-determining locus within region non-recombination. To better understand early chromosome evolution, it important to determine process by which recombination suppressed around determining genes. We have used dioecious angiosperm kiwifruit Actinidia chinensis var. chinensis, has an active-Y system, study rates locus, events...
Abstract Background The genetic control of sex determination in teleost species is poorly understood. This partly because the diversity mechanisms that determine this large group vertebrates, including constitutive genes linked to chromosomes, polygenic mechanisms, environmental factors, hermaphroditism, and unisexuality. Here we use a de novo genome assembly New Zealand silver trevally ( Pseudocaranx georgianus ) together with sex-specific whole sequencing data detect sexually divergent...
Asexual seed formation (apomixis) has been observed in diverse plant families but is rare crop plants. The generation of apomictic crops would revolutionize agriculture, as clonal production provides a low cost and efficient way to produce hybrid seed. Hieracium (Asteraceae) model system for studying the molecular components gametophytic apomixis (asexual reproduction). In this study, reference transcriptome was produced from undergoing key events apomeiosis, parthenogenesis autonomous...
During analysis of kiwifruit derived from hybrids between the high vitamin C (ascorbic acid; AsA) species Actinidia eriantha and A. chinensis, we observed bimodal segregation fruit AsA concentration suggesting major gene segregation. To test this hypothesis, performed whole-genome sequencing on pools hybrid genotypes with either or low fruit. Pool-GWAS (genome-wide association study) revealed a single Quantitative Trait Locus (QTL) spanning more than 5 Mbp chromosome 26, which denote as...
Pilosella piloselloides var. praealta (syn. P. ; Hieracium praealtum ) is a versatile model used to study gametophytic apomixis. In this system apomixis controlled by three loci: one that controls the avoidance of meiosis ( LOA ), fertilization LOP and third autonomous endosperm formation AutE ). Using unique polyhaploid mapping approach locus was mapped 654 kb genomic interval syntenic linkage group 8 Lactuca sativa . Polyhaploids form through action dominant determinant at , so region...
Background: Genetic diversity provides the basic substrate for evolution. variation consists of changes ranging from single base pairs (single-nucleotide polymorphisms, or SNPs) to larger-scale structural variants, such as inversions, deletions, and duplications. SNPs have long been used general currency investigations into how genetic fuels However, variants can affect more in genome than be responsible adaptive phenotypes due their impact on linkage recombination. In this study, we...

During analysis of kiwifruit derived from hybrids between the high AsA species Actinidia eriantha and A. chinensis var chinensis, we observed bimodal segregation fruit concentration suggesting major gene segregation. To test this hypothesis performed whole-genome sequencing on pools low tetraploid var. deliciosa x backcross families. Pool-GWAS revealed a single QTL spanning more than 5 Mbp chromosome 26, which denote as qAsA26.1. A co-dominant PCR marker was used to validate association in...
