摘要：

DWARF17 (D17/HTD1) is a well-defined rice strigolactone (SL) biosynthesis gene that influences rice tiller development and the production of rice. To investigate whether SLs play a role in the regulation of rice’s defense against the white-backed planthopper (WBPH, Sogatella furcifera), we compared a SL-biosynthetic defective mutant (d17) with WT rice plants. Our olfactory bioassay results revealed that WBPHs are attracted to d17 plants, which may be attributed to changes in rice volatile substances. Hexanal, a volatile substance, was signific...
