Sex and the Catasetinae (Darwin's favourite orchids).

Molecular phylogenetics and evolution - 1 Apr 2016

Pérez-Escobar Oscar Alejandro, Gottschling Marc, Whitten W Mark, Salazar Gerardo, Gerlach Günter

Abstract excerpt

Two sexual systems are predominant in Catasetinae (Orchidaceae), namely protandry (which has evolved in other orchid lineages as well) and environmental sex determination (ESD) being a unique trait among Orchidaceae. Yet, the lack of a robust phylogenetic framework for Catasetinae has hampered deeper insights in origin and evolution of sexual systems. To investigate the origins of protandry and ESD in...
