Repressor of jasmonate (JA) responses. Acts as a repressor of JA-induced resistance to the bacterial blight pathogen Xanthomonas oryzae pv. oryzae (Xoo) (PubMed:23104764). 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 (PubMed:23889289). Interacts with BHLH148 (PubMed:21332845). Interacts with COI1B in a coronatine-dependent manner. Coronatine is an analog of jasmonoyl isoleucine (JA-Ile) (PubMed:23320078, PubMed:23104764). Interacts with TIFY5/JAZ2, TIFY6B/JAZ4, TIFY9/JAZ5, TIFY11A, TIFY11D/JAZ12, TIFY11G/JAZ15 and NINJA1 (PubMed:23104764). Mainly localized in the nucleus. By jasmonate, and cold, drought and salt stresses. Down-regulated by abscisic acid (ABA) (PubMed:19618278). Induced by wounding (PubMed:21332845, PubMed:24033451). Induced by blue light (PubMed:24033451). The jas domain (177-202) is required for interaction with COI1. Ubiquitinated (Probable). Increase in jasmonoyl isoleucine (JA-Ile) levels mediates its degradation via COI1B-mediated proteasome pathway (PubMed:23104764). Plants over-expressing a truncated form of TIFY10C/JAZ8 display a jasmonate-insensitive phenotype and have altered expression of jasmonate-responsive genes. Belongs to the TIFY/JAZ family.
