An ordered draft sequence of the 17-gigabase hexaploid bread wheat (Triticum aestivum) genome has been produced by sequencing isolated chromosome arms. We have annotated 124,201 gene loci distributed nearly evenly across homeologous chromosomes and subgenomes. Comparative analysis subgenomes extant diploid tetraploid relatives showed that high similarity structural conservation are retained, with limited loss, after polyploidization. However, genomes there was evidence dynamic gain,...
The allohexaploid bread wheat genome consists of three closely related subgenomes (A, B, and D), but a clear understanding their phylogenetic history has been lacking. We used assemblies five diploid relatives to analyze genome-wide samples gene trees, as well estimate evolutionary relatedness divergence times. show that the A B genomes diverged from common ancestor ~7 million years ago these gave rise D through homoploid hybrid speciation 1 2 later. Our findings imply present-day is product...
Allohexaploid bread wheat ( Triticum aestivum L.) provides approximately 20% of calories consumed by humans. Lack genome sequence for the three homeologous and highly similar genomes (A, B, D) has impeded expression analysis grain transcriptome. We used previously unknown information to analyze cell type–specific genes in developing identified distinct co-expression clusters reflecting spatiotemporal progression during endosperm development. observed no global but type– stage-dependent...
The Wheat@URGI portal has been developed to provide the international community of researchers and breeders with access bread wheat reference genome sequence produced by International Wheat Genome Sequencing Consortium. browsers, BLAST, InterMine tools have established for in-depth exploration together additional linked datasets including physical maps, variations, gene expression, genetic phenomic data from other collaborative projects already stored in GnpIS information system. provides...
Thanks to their ability move around and replicate within genomes, transposable elements (TEs) are perhaps the most important contributors genome plasticity evolution. Their detection annotation considered essential in any sequencing project. The number of fully sequenced genomes is rapidly increasing with improvements high-throughput technologies. A automated de novo process for TEs therefore required cope deluge sequence data. However, all procedures error-prone, an procedure TE...
Endogenous viral elements (EVEs) are sequences that integrated in the nuclear genomes of their hosts and signatures infections may have occurred millions years ago. The study EVEs, coined paleovirology, provides important insights into virus evolution. Caulimoviridae is most common group EVEs plants, although presence has often been overlooked plant genome studies. We refined methods for identification caulimovirid interrogated a broad diversity taxa, from algae to advanced flowering plants....
