Identification and characterization of COI1-dependent transcription factor genes involved in JA-mediated response to wounding in Arabidopsis plants.
The phytohormone jasmonic acid (JA) is an important signaling molecular involved in many developmental and physiological processes, especially in the response of plants to wounding. In this study, we adopted a new strategy, taking into consideration the microarray data of the CHX treatment, to identify 15 COI1-dependent JA-inducible transcription factors (JCTFs) that have distinct expression patterns in response to wounding. After the analysis on the JCTFs over-expressor plants, we identified four JCTFs, i.e., WRKY18, At1g74930 and At3g53600 in addition to AtMYC2, as the positive regulators in the JA-mediated signaling pathway in response to Arabidopsis wounding.
