Abstract
Plants are exposed to many types of abiotic or biotic stresses. Many researchers have analyzed the mechanism of these stress responses using Arabidopsis plants. At the present day, creation of plants having tolerance for several abiotic or biotic stresses has reported. On the other hand, insect damage is very serious problem that decrease the crop yields. However, the mechanism of plant response to feeding damage has not been well understood. Thrips are cell content feeding insect that penetrate single cells with stylet to suck out the contents. In addition, thrips transmit the virus from plant to plant. We used western flower thrips (Frankliniella occidentalis) in our analyses. In this time, we performed the GeneChip analyses (Affymetrix: ATH1 chip) of Arabidopsis plants attacked by thrips. We report here the function of Jasmonic acid (JA), Ethylene (ET) and Salicylic acid (SA) in thrips feedind.
