(3R,7S)‐12‐Hydroxy‐jasmonoyl‐l‐isoleucine is the genuine bioactive stereoisomer of a jasmonate metabolite in Arabidopsis thaliana

SUMMARY The oxylipin plant hormone (3R,7S)‐jasmonoyl‐l‐isoleucine [or (+)‐7‐iso‐jasmonoyl‐l‐isoleucine, JA‐Ile] is widely recognized as a plant defense hormone against pathogens and chewing insects. The metabolism of JA‐Ile into 12‐OH‐JA‐Ile and 12‐COOH‐JA‐Ile is the central mechanism for the inacti...
