Probably involved in long chain fatty-acid beta-oxidation prior to gluconeogenesis during germination and subsequent seedling growth. Involved in systemic jasmonic acid (JA) biosynthesis after wounding and may be during senescence. acetyl-CoA + an acyl-CoA = a 3-oxoacyl-CoA + CoA Lipid metabolism; fatty acid metabolism. Homodimer. Expressed in seedlings and wounded leaves. Slightly induced in leaves during senescence. Induced by jasmonic acid (JA) and systemically by wounding. Slightly induced by dehydration. Belongs to the thiolase-like superfamily. Thiolase family.
