Repressor of jasmonate (JA) responses. Acts as a repressor of JA-induced resistance to the bacterial blight pathogen Xanthomonas oryzae pv. oryzae (Xoo). Regulates JA-induced accumulation of linalool at the transcriptional level of linalool synthase gene LIS. Linalool is important for resistance to bacterial blight pathogen Xoo. Interacts with BHLH148. Interacts with COI1B in a coronatine-dependent manner. Coronatine is an analog of jasmonoyl isoleucine (JA-Ile). Interacts with TIFY5/JAZ2, TIFY6B/JAZ4, TIFY9/JAZ5, TIFY11A, TIFY11D/JAZ12 and TIFY11G/JAZ15. Mainly localized in the nucleus. The jas domain (177-202) is required for interaction with COI1. Ubiquitinated. Increase in jasmonoyl isoleucine (JA-Ile) levels mediates its degradation via COI1B-mediated proteasome pathway. Belongs to the TIFY/JAZ family.
