Journal Article
Sex pheromone biosynthetic pathways are conserved between moths and the butterfly Bicyclus anynana
2014
Overview
Although phylogenetically nested within the moths, butterflies have diverged extensively in a number of life history traits. Whereas moths rely greatly on chemical signals, visual advertisement is the hallmark of mate finding in butterflies. In the context of courtship, however, male chemical signals are widespread in both groups although they likely have multiple evolutionary origins. Here, we report that in males of the butterfly
Bicyclus anynana
, courtship scents are produced
de novo
via biosynthetic pathways shared with females of many moth species. We show that two of the pheromone components that play a major role in mate choice, namely the (
Z
)-9-tetradecenol and hexadecanal, are produced through the activity of a fatty acyl Δ11-desaturase and two specialized alcohol-forming fatty acyl reductases. Our study provides the first evidence of conservation and sharing of ancestral genetic modules for the production of FA-derived pheromones over a long evolutionary timeframe thereby reconciling mate communication in moths and butterflies.
Little is known about the evolutionary origins of the genes involved in butterfly pheromone synthesis. Here, Liénard
et al.
show that the biosynthetic pathways involved in the production of male courtship scents of the butterfly,
Bicyclus anynana
, are shared with females of many moth species.
