Cross-species comparisons of floral transcriptomes to identify the genes resposible for floral oligosulfide biosynthesis.
Oligosulfides, a set of sulfur-containing volatile compounds that attracts saprophilous pollinators, is emittedd by various flowering plants, although its biosynthetic mechanisms have not yet been explored. To identify the biochemical and genetic basis of the production of floral oligosulfides, comparative transcriptome analyses were conducted for the plant genera Asarum, Amorphophallus, and Eurya,
