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)
More and more users joined in social network. The precise social trust value is critical for application system such as recommendation system. To a user, the egocentric network is formed by the user, his friends and social relationships between him and other users. We proposed an algorithm for inferring dynamic trust based on trust chains and interactions.(More)
Hydroperoxide lyases (HPLs) play important roles in modulating plant defense by regulating the release of green leaf volatiles (GLVs) and the jasmonic acid (JA) pathway. CsiHPL1—a chloroplast-localized tea gene that encodes HPL—was previously cloned and predicted to be a regulator of plant defense responses. CsiHPL1 was expressed constitutively in(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)
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)
Spam is an imperative problem to the email communication today. Different users may have different views on judging spam which makes it difficult to filter spam from normal emails for email server. We found users with similar interest may have similar opinions. So in this paper, we proposed a spam filtering approach in which a collaborative and personalized(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)
Malicious codes can propagate rapidly by exploiting software vulnerabilities. In order to prevent the explosion of malicious codes in P2P networks, an automatic patching mechanism based on social computing is proposed. The security server generates automatic patches, and then selects the vulnerable nodes to push automatic patches. Automatic patches(More)
