Natural selection on floral volatile production in Penstemon digitalis: highlighting the role of linalool.

Plant signaling & behavior - 1 Jan 2013

Parachnowitsch Amy L, Burdon Rosalie C F, Raguso Robert A, Kessler André

Abstract excerpt

Natural selection is thought to have shaped the evolution of floral scent; however, unlike other floral characters, we have a rudimentary knowledge of how phenotypic selection acts on scent. We found that floral scent was under stronger selection than corolla traits such as flower size and flower color in weakly scented Penstemon digitalis. Our results suggest that to understand evolution in floral phenotypes,...
