ACL — Phaseolus vulgaris

Summary

PHAVU_003G248075 (PvACL) on French bean chromosome 3 encodes a member of the MES/HNL family with an alpha/beta hydrolase fold, possessing multiple esterase and hydroxynitrile lyase activities including mandelonitrile lyase, polyneuridine-aldehyde esterase, and methyl esterase activities toward jasmonate, salicylate, and IAA. The gene is associated with defense responses to insects, systemic acquired resistance via salicylic acid signaling, wounding, UV-B, cold, and innate immunity. It is linked to jasmonic acid and salicylic acid metabolism, oxylipin anabolism, glycoside breakdown, indole alkaloid and phenylpropanoid anabolism, and embryo development ending in seed dormancy. The product localizes to the vacuole, cytosol, plasma membrane, and nucleus. Studies of related genes in other species connect the family to salt and osmotic stress tolerance, ABA sensitivity, systemic acquired resistance, spider mite resistance, and triterpene and sterol accumulation.
