10.15 Harnessing natural diversity to discover the rules of flower color evolution
By Stacey Dewitt Smith, Department of Ecology and Evolutionary Biology, University of Colorado, Boulder (Homepage)
Abstract
One of the most striking aspects of the angiosperm
radiation is their diversity of flower colors. In this talk, I will
explore the mechanisms by which flower colors evolve and examine the
relationship between micro- and macroevolution of color. Work in my
group and others points to a high degree of convergence in the genetic
and developmental mechanisms that lead to flower color transitions among
lineages. Within species variation in flower color arises by diverse and
often distinct mechanisms, pointing to a challenge in relating the
commonly observed color morphs within species to macroevolutionary
transitions.
