  abstract = {{L}ipoxygenases ({LOX}s) are enzymes responsible for lipid peroxidation processes during plant defence responses to pathogen infection. {J}asmonates are lipid-derived signals that mediate plant stress responses with chloroplastic {LOX}s implicated in the biosynthesis of oxylipins like jasmonic acid ({JA}). {H}ypersensitive reaction ({HR}) cell death of cotton to the incompatible race 18 of {X}anthomonas campestris pathovar malvacearum ({X}cm) is associated with 9{S}-lipoxygenase activity and expression of a 9-{LOX} {G}h{LOX}1. {H}ere, we report the cloning of cotton ({G}ossypium hirsutum {L}.) {LOX} gene {G}h{LOX}2. {S}equence analysis showed that {G}h{LOX}2 is a putative 13-{LOX} with a chloroplast-transit peptide in the amino acid terminus. {G}h{LOX}2 was found to be significantly expressed in the first hour of {X}cm-induced {HR}. {I}nvestigation into {LOX} signalization on cotyledons incubated with methyl-jasmonate ({M}e{JA}) or infiltrated with salicylic acid ({SA}) or ethylene ({ET}) revealed that the first two treatments induced {G}h{LOX}2 gene expression. {O}ur results show that {G}h{LOX}2 gene expression occurred at the stage of the {HR} prior biochemical events previously highlighted. {T}he role that {G}h{LOX}2 may have in the defence strategy of cotton to {X}cm is discussed regarding the {HR}.},
