Regulating chewing and sucking pests
Plants have numerous signaling pathways involved in defense responses and one of them is mediated by oxylipins, lipid-derived signaling molecules including jasmonic acid. Regulation of the genes encoding enzymes involved in the biosynthesis of these compounds are consequently important for plant defense responses. Now, Yonggen Lou and colleagues from Zhejiang University in China has studied one of them in detail, namely the chloroplast-localized Osr9-LOX1 from rice. They found that antisense expression of the gene led to a decrease in wound-induced compounds but an increase in herbivory-induced compounds, the combination of which was associated with increased resistance to the chewing larvae of striped stem borer (Chilo suppressalis). On the other hand, these plants were more susceptible to the sap-sucking brown planthopper (Nilaparvata lugens). The authors suggest that Osr9-LOX1 may play a central role in regulating the cross-talk between jasmonic acid and salicylic acid and thereby directing resistance to either chewing or sucking herbivores in rice.
