Influence of infestation by rice leaf folder Cnaphalocrocis medinalis on levels of defense chemicals and signal molecules in rice
The changes in levels of hydrogen peroxide, salicylic acid and jasmonic acid, and defenserelated chemicals were investigated in rice plants infested by the rice leaf folder Cnaphalocrocis medinalis. The results show that C. medinalis infestation enhanced significantly the levels of hydrogen peroxide...

| description | The changes in levels of hydrogen peroxide, salicylic acid and jasmonic acid, and defenserelated chemicals were investigated in rice plants infested by the rice leaf folder Cnaphalocrocis medinalis. The results show that C. medinalis infestation enhanced significantly the levels of hydrogen peroxide (0.5 and 24 h after infestation) and salicylic acid (0.5, 1 and 24 h after infestation) but not of jasmonic acid in plants. Compared to the control, C. medinalis infestation resulted in increases in concentrations of trypsin inhibitors and six unknown defense chemicals in infested leaves, but only three of the six unknown chemicals were enhanced in leaf sheaths of the infested plants. Exogenous application of hydrogen peroxide or salicylic acid only increased level of one of the six unknown chemicals in plants. This suggests that some defense chemicals in rice plants are systematically induced by C. medinalis infestation, whereas some are locally induced, and C. medinalis-induced rice defense response is a result of crosstalk among a number of signaling pathways. |
