MGOUN3: evidence for chromatin-mediated regulation of FLC expression.

abstract：:Jasmonates are signaling compounds that regulate plant responses to stress. Jasmonic acid (JA) is the direct precursor of the bioactive plant hormone JA-isoleucine (JA-Ile), the ligand of the CORONATINE INSENSITIVE 1-jasmonate ZIM-domain (COI1-JAZ) co-receptor complex. JA, its methyl ester, and three furanonyl esters ...
