Transcription factor that acts downstream of MYC2 in the jasmonate-mediated response to Botrytis cinerea infection (PubMed:28733419). With MYC2 forms a transcription module that regulates wounding-responsive genes (PubMed:28733419). Involved in jasmonate- and coronatine-mediated stomatal reopening in response to Pseudomonas syringae pv tomato DC3000 infection (PubMed:25005917). Regulates the expression of threonine deaminase 2 (TD2) through promoter binding (PubMed:28733419). Expressed in guard cells of the epidermis. Induced by jasmonate (JA) (PubMed:25005917, PubMed:28733419, PubMed:30610166). Induced by wounding (PubMed:28733419, PubMed:25005917). Induced by infection with the fungal pathogen Botrytis cinerea (PubMed:28733419). Induced by coronatine (PubMed:25005917). The NAC domain includes a DNA binding domain and a dimerization domain. Plants silencing JA2L exhibit enhanced susceptibility to the fungal pathogen Botrytis cinerea.
