Transcriptional activator that binds to the G-box motif (5'-AACGTG-3') found in the promoter of the jasmonate-induced gene LAPA1 (PubMed:15231736). Acts as negative regulator of blue light-mediated photomorphogenesis and positively regulates root growth (PubMed:24483714). Promotes growth in response to the phytohormones abscisic acid (ABA) and jasmonate (JA) (PubMed:24483714). Binds to the G-box motif (5'-CACGTG-3') of the RBCS-3A gene promoter (PubMed:24483714). Acts downstream of the jasmonate (JA) receptor to orchestrate JA-mediated activation of plant responses (PubMed:28733419). Positively regulates both wound-responsive and pathogen-responsive genes through MYC2-targeted transcription factors (MTFs) involved in early response to JA (PubMed:28733419). With JA2L forms a transcription module that regulates wounding-responsive genes (PubMed:28733419). With ERF.C3 forms a transcription module that regulates pathogen-responsive genes (PubMed:28733419). Plays a critical role in orchestrating JA-mediated defense gene expression during Botrytis cinerea infection (PubMed:28733419). Regulates negatively defense responses to root-knot nematodes, potentially by mediating crosstalk among the hormones strigolactones, abscisic acid (ABA) and jasmonate (JA) (PubMed:30576511). Regulates the termination of JA-mediated defense responses by specifically binding the G-box (5'-CACATG-3') motifs in the promoters of MTB1, MTB2 and MTB3, which are transcription factors that negatively regulates JA signaling (PubMed:30610166). May be involved in JA-induced chilling tolerance, possibly by ameliorating the antioxidant enzyme system of fruit and increasing proline and lycopene levels (PubMed:29528226). Interacts (via N-terminus) with MED25 (PubMed:30610166). Interacts (via N-terminus) with JAZ7 (PubMed:28733419, PubMed:30610166). MED25 and JAZ7 compete with each other to bind to MYC2 (PubMed:30610166). Interacts (via N-terminus) with MTB1 (PubMed:30610166). MTB1 and MED25 compete with each other to bind to MYC2 (PubMed:30610166). Expressed at low levels in roots, stems, leaves, flowers and fruits. Induced by methyl jasmonate (PubMed:15231736, PubMed:28733419). Induced by wounding (PubMed:15231736). Induced by infection with the fungal pathogen Botrytis cinerea (PubMed:28733419). Induced in fruit by storage in cold (PubMed:29528226). Induced by hydrogen peroxide and infection with root-knot nematodes (PubMed:30576511). Plants over-expressing MYC2 exhibit increased number of branches with reduced internode distance (PubMed:24483714). Plants silencing MYC2 exhibit increased susceptibility to infection by the fungal pathogen Botrytis cinerea (PubMed:28733419). Plants silencing MYC2 show decreased susceptibility to infection by root-knot nematodes (PubMed:30576511). Contains a degenerate basic motif not likely to bind DNA.
