First observed in lateral root primordia (LRP), from the first pericycle divisions. Later expressed in lateral roots. Expression is greatly increased in leaves during leaf senescence.
13S-lipoxygenase that can use linolenic acid as substrates. Plant lipoxygenases may be involved in a number of diverse aspects of plant physiology including growth and development, pest resistance, and senescence or responses to wounding. Catalyzes the hydroperoxidation of lipids containing a cis,cis-1,4-pentadiene structure (By similarity).
