This entry includes a group of plant glycerolipid A1 lipases, including PLIP1/2/3 from Arabidopsis. PLIP1 is a plastid phospholipase A1 that releases polyunsaturated fatty acids from chloroplast phosphatidylglycerol, leading to the export of the fatty acids to the ER for seed oil biosynthesis [
]. PLIP2/3 are also present in the chloroplasts. They respond to ABA and are involved in jasmonic acid biosynthesis [].
