Abstrakt:
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 the homeologous chromosomes
and subgenomes. Comparative gene analysis of wheat subgenomes and extant diploid
and tetraploid wheat relatives showed that high sequence similarity and structural
conservation are retained, with limited gene loss, after polyploidization. However, across
the genomes there was evidence of dynamic gene gain, loss, and duplication since the
divergence of the wheat lineages. A high degree of transcriptional autonomy and no
global dominance was found for the subgenomes. These insights into the genome
biology of a polyploid crop provide a springboard for faster gene isolation, rapid genetic
marker development, and precise breeding to meet the needs of increasing food
demand worldwide.
