Green leaf volatiles (GLVs), the products of the hydroperoxide lyase (HPL) branch of the oxylipin pathway, play important roles in plant defense responses to both insect pests and pathogens. However, little is known about the role of GLVs in the defense responses of rice to the white-backed planthopper (WBPH, Sogatella furcifera (Horváth)). Here, we found(More)
Volatile organic compounds derived from non-host plants, Ocimum basilicum, Rosmarinus officinalis, Corymbia citriodora, and Ruta graveolens, can be used to mask host plant odors, and are repellent to the tea geometrid, Ectropis obliqua. Volatile compounds were collected by headspace absorption, and the components were identified and quantified by using gas(More)
Herbivore-induced plant volatiles have been reported to play a role in the host-searching behavior of herbivores. However, next to nothing is known about the effect of volatiles emitted from tea plants infested by Ectropis obliqua larvae on the behavior of conspecific adults. Here, we found that tea plants infested by E. obliqua caterpillars for 24 h were(More)
We investigated the effect of the SHAM treatment of tea plants on their induced defense on a tea geometrid (TG), Ectropis obliqua Prout. Treatment of tea leaves with SHAM reduced the performance of TG and TG-elicited level of the lipoxygenase gene CsiLOX1 and the putative allene oxide synthase gene CsiAOS1. The release of wound-induced green leaf volatiles(More)
Xylanase inhibitors have been reported to play an important role in plant defense against fungal pathogens. However, little to nothing is known about their role in defense against herbivores. Here, we cloned a rice xylanase-inhibiting protein (XIP)-type gene OsHI-XIP whose encoding protein is located in the endoplasmic reticulum (ER). Transcriptional(More)
Plants can respond to herbivorous attack with induced defense mechanisms. Plant elicitors play vital roles in inducing the plant defense response against herbivores. In this study, we investigated the effect of (Z)-3-hexenol (z3HOL), an important component of green leaf volatiles (GLVs), on the induced defense against a tea geometrid (TG) Ectropis obliqua(More)
