However, how it works remains unclear. Here, we investigated the levels of salicylic acid (SA), jasmonic acid (JA), ethylene, and H2O2, all of which are known signaling molecules that play important roles in induced plant defense in rice plants treated with ¦Â-glucosidase, and compared these to levels in plants infested by the rice brown planthopper Nilaparvata lugens (St l). Results showed that wounding and treatment by ¦Â-glucosidase increased the levels of SA, ethylene, and H2O2, but not JA, in all plants compared to control plants. The signaling pathways activated by ¦Â-glucosidase treatment are similar to those activated by an infestation by N. lugens, although the magnitude and timing of the signals elicited by the two treatments are different. This may explain why both treatments have similar volatile profiles and are equally attractive to the parasitoid Anagrus nilaparvatae Pang et Wang. %K rice %K Nilaparvata lugens %K signaling pathway %K jasmonic acid %K salicylic acid %K ethylene %K hydrogen peroxide %K tritrophic interaction %U http://link.springer.com/article/10.1007/s11434-008-0048-4
