Gardener’s Delight Offers Glimpse Into The Evolution Of Flowering Plants

For the first time scientists have proved that Arabidopsis and Thalictrum have genes that do the exact same kind of things in spite of the millions of years of evolution that separate the two species. The function of these organ-identity genes appears to be highly conserved according to the new research, meaning the gene is essential and its function has been maintained despite the formation of new species. Identifying the genetic and biochemical basis of double flowering in Thalictrum suggests the class of genes that likely underlie other widespread double-flower varieties.
