The paper:
O. Jaillon et al., "The grapevine genome sequence suggests ancestral hexaploidization in major angiosperm phyla," Nature, 449:463–68, 2007. (Cited in 133 papers)
The finding:
A team of researchers in France and Italy sequenced the genome of the common grapevine, Vitis vinifera, and found evidence of a whole genome tripling event prior to the divergence of monocots and dicots, the two main classes of flowering plants. The sequence "gave us insights into what early dicots looked like," says Andrew Paterson, of the University of Georgia.
The impact:
Polyploidization has been linked with increased vigor and enhanced adaptation to different conditions. Thus, genome tripling could be "responsible for the great success of flowering plants on earth," says lead author Patrick Wincker of Genoscope, the French National Sequencing Center, in an email.
The follow-up:
Last year, Paterson used the grapevine genome to successfully verify a phylogenetic method to infer ancestral genome ...
