Oat genome — sequence of a superfood

The analysis of the 11-gigabase, hexaploid oat genome reveals a mosaic chromosome structure with complex rearrangements related to polyploidization. The high-quality oat reference genome will facilitate the molecular identification of health food traits and the implementation of genomics-based oat breeding.

Cultivated oat (Avena sativa; 2n = 6x = 42; AACCDD genome) is a hexaploid species that arose through hybridization between a tetraploid and a diploid oat progenitor. As a consequence of the polyploidization, the oat genome is very large (more than triple the size of the human genome) and complex. The genus Avena also includes a series of diploid and polyploid wild, weedy and cultivated species. Using short-read sequencing and chromosome conformation capture, Kamal et al. produced a highly complete and fully annotated assembly of the 21 chromosomes of oat cultivar ‘Sang’. The same sequencing strategy was deployed previously to successfully assemble the large wheat, barley and rye genomes2,3,4,5. In addition to cultivated oat, Kamal et al. assembled the genomes of the diploid and tetraploid wild Avena species A. longiglumis and A. insularis, which are presumed A and CD subgenome progenitors of cultivated oat, respectively.
