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.
We analyzed the interaction between Arabidopsis and western flower thrips (Frankliniella occidentalis), which is one of the most serious insect pests. Thrips is 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 focused on the function of the immunity-related plant hormones jasmonate (JA), ethylene (ET), and salicylic acid (SA) on plant tolerance to thrips feeding.
