Today's Nature issue reports the sequence of the soybean genome by Schmutz et al. Soybean is one of the most important legumes which went through two genome duplications about 59 and 13 million years ago, leading to multiple copies of nearly 75% of the genes, followed by gene diversification, loss and chromosome rearrangements. The 1.1Gb, 20 chromosome genome of Glycine max var. Williams-82 is predicted to have 46, 430 protein coding genes, 70% more than Arabidopsis. The genome information is available on Phytozome.
