Thionins are a group of antimicrobial polypeptides that form part of the plant's defense mechanism against pathogens. The Thi 2.1 thionin gene of Arabidopsis thaliana has been shown to be inducible by jasmonic acid (JA), an oxylipin-like hormone derived from oxygenated linolenic acid and synthesized via the octadecanoid pathway. The JA-dependent regulation of the Thi 2.1 gene...
