One gene class causes widespread double flowered varieties

Growers might be interested that scientists figured out what’s going on genetically in the process of double flowering, quotes Sandra Hines in a news post on the site of the University of Washington (US). In her article ‘Gardener’s delight offers glimpse into the evolution of flowering plants’ she describes how scientists discovered the genes which cause double flowered Arabidopsis and Thalictrum. “These genes do the exact same kind of things in spite of the millions of years of evolution that separates the two species.” Scientists now suggest that a class of genes likely underlie other widespread double-flowered varieties. In terms of applications, those who are interested in creating double flowers can now have more knowledge about which gene they have to treat to get that flower form.
Collaboration with German university
The scientific work was funded by the US National Science Foundation, including a research experience for undergraduate fellowship for co-author Theadora Tolkin, now a doctoral student at New York University. Other co-authors are Alessandra Sullivan, former Di Stilio lab member and current doctoral student at the University of Washington; and collaborators Rainer Melzer and Günter Theiβen with Friedrich Schiller University in Germany.
