Duplication and selection in ?-ketoacyl-ACP synthase gene lineages in the sexually deceptive Chiloglottis (Orchidaceace)
BACKGROUND AND AIMS: The processes of gene duplication, followed by divergence and selection, probably underpin the evolution of floral volatiles crucial to plant-insect interactions. The Australian sexually deceptive Chiloglottis orchids use a class of 2,5-dialkylcyclohexan-1,3-dione volatiles or 'chiloglottones' to attract specific male wasp pollinators. Here, we explore the expression and evolution of fatty acid pathway genes implicated in chiloglottone biosynthesis. METHODS: Both...[Show more]
