茶尺蠖为害提高邻近茶苗对茶尺蠖幼虫的防御能力
Infestation of Ectropis obliqua Enhances Neighboring Tea Plant Defenses Against Conspecific Larvae
摘要
Abstract
In this study, the effect of herbivore-induced plant volatiles (HIPVs) from tea plant on the defense responses of neighboring tea plants was analyzed. The expression levels of defense-related genes, the content of defense compound in tea and the mass of Ectropis obliqua (TG) larvae were measured respectively. Compared with the control plants, the results showed that HIPVs released from TG-infested tea plants significantly induced the relative expression levels of CsiLOX1 and CsiACS1 in the neighboring tea plants within 24 h and 12 h. TG-induced expression of CsiLOX1 and CsiACS1 were also enhanced by HIPVs. Three days after HIPVs exposure, the polyphenol oxidases(PPOs) activity in the treated tea leaves was 1.36-fold higher than that of control. Meanwhile, the HIPVs-treated tea plants reduced the performance of TG. The above results showed that volatiles released from TG-infested tea can convey information to those neighboring plants and then trigger the induced defense responses against TG by modulating JA and ET signaling pathways in tea.关键词
