metabolism allene oxide synthase (AOS) and 13-hydroperoxide lyase (HPL) pathways, are best recognized as producers of defense compounds against biotic challenges, role of these two oxylipin branches in plant tolerance to the abiotic stress, namely excessive light, overview. Allen oxide synthase (AOS) and hydroperoxide lyase (HPL), the two enzymes functional in parallel branches of oxylipin pathway, compete for the common substrate hydroperoxide of linolenic acid (i.e. (9Z,11E,15Z)-13-hydroperoxy-9,11,15-octadecatrienoic acid) Arabidopsis thaliana
