The hypothesis that arachidonic acid (AA) induction of sesquiterpene accumulation and browning in potato (Solanum tuberosum) is mediated by a lipoxygenase metabolite of AA was tested using lipoxygenase inhibitors. Salicylhydroxamic acid (SHAM) and 3-amino-1-(3-trifluoromethylphenyl)-2-pyrazoline hyd...
