摘要： Herbivores harbor gut microbes that affect their development and contribute to their nutrition, reproduction, and survival. Plant defenses could target the herbivore's beneficial gut microbes, but this has not been well studied in rice. In this context, we identified a rice terpene synthase gene, Os04g0341500. It was strongly induced after feeding by rice striped stem borers (SSB, Chilo suppressalis), and it can catalyze the (E)-beta-farnesene (E beta f) synthesis. When added to artificial diets, E beta f impaired the development and survival of SSB larvae. High-throughput amplicon sequencing revealed that SSB fed on E beta f were decreased in beneficial gut microbes, compared to those feeding on the corresponding control feed. In vitro feeding of E beta f suggested that this antimicrobial sesquiterpene directly inhibited the growth of SSB gut microbes. The present study suggested that the E beta f-induced decrease of relative abundance of gut microbes potentially impairs larval development and survival in SSB.
