Tomato Genome Update - 2
Analysis of the recently sequence tomato genome in comparison to potato and grape genome reveal that massive genome duplication events shaped the evolution of these plants. Ancestors of tomato genome underwent whole genome triplication twice, one very early in a common eudicot ancestor shared with rosid and the second more recent triplication in the ancestor of tomato and potato followed by widespread gene loss. This recent triplication has occurred around 71 million years ago well before divergence of tomato and potato which took place approximately
