摘要：

To clarify genetically the involvement of two Arabidopsis NADPH oxidases (AtrbohD and AtrbohF) in the jasmonic acid (JA) signaling pathway, we characterized single knockout mutants lacking either Atrboh. The accumulation of reactive oxygen species (ROS) and expression of the genes regulated by MYC2, a transcription factor involved in the JA-evoked response, were significantly suppressed by treatment with methyl JA (MeJA) in both mutants. Further experiments using knockout mutants lacking CORONATINE-INSENSITIVE1 (COl1), a master regulator of the JA-evoked response, and MYC2 indicated a possibility that the production of ROS via Atrbohs depends on the function of COl1, but not MYC2.
