Abstract: | "Green leaf volatiles (GLVs) play a vital role in enhancing herbivore-associated defense responses, but the mechanism by which they precisely regulate such responses is not well understood. (Z)-3-Hexenol (z3HOL), an important component of GLVs, effectively activates the defense of tea plants (Camellia sinensis) against a tea geometrid (TG) Ectropis obliqua Prout. To elucidate the molecular mechanisms of defense activation by z3HOL, RNA-Sequencing was employed to investigate the effect of z3HOL on transcriptome responses to TG in tea plants. A total of 318 upregulated genes were identified, and expression of 10 unigenes was validated by quantitative real-time PCR. Among these 318 upregulated genes, 56 were defense-related, including 6 key enzyme genes in jasmonic acid, and ethylene biosynthesis, 24 signal transduction genes, and 12 insect-responsive transcription factors. Most of the defense-related genes are induced by JA, TG, or wounding treatments, suggesting that JA signaling plays a vital role in z3HOL-induced tea defense against TG" |
