Abstract excerpt

Jasmonates, key plant immune hormones, derive almost exclusively from omega-3 polyunsaturated fatty acids (n3-PUFAs), yet the evolutionary rationale for this substrate specificity remains unresolved. This study employed the liverwort Marchantia polymorpha to investigate the functional roles of omega-3 fatty acid desaturases (n3-FADs) in n3-PUFA metabolism, jasmonate biosynthesis and plant defense....
