Specific 13-LOX functions in wounded Arabidopsis rosettes. All four 13-LOXs produce JA precursors in wounded leaves and all four play roles in defense against lepidopteran herbivores. LOX2 is expressed throughout soft tissues (including the mesophyll) but not (or at very low levels) in the mature leaf vasculature. LOX3, LOX4, and LOX6 are primarily expressed in phloem- and xylem-associated cells in both developing and mature leaf veins. Only the functions that are largely specific to distinct LOXs in Arabidopsis leaves are emphasized. From Chauvin et al. (2013, 2016), Glauser et al. (2009), Grebner et al. (2013), and this work.
