ACL — Phaseolus vulgaris

Summary

PHAVU_003G248025 (PvACL) on French bean chromosome 3 encodes a member of the MES/HNL family with an alpha/beta hydrolase fold, exhibiting multiple esterase and hydroxynitrile lyase activities including mandelonitrile lyase, carboxylesterase, and lipase activity. The gene is associated with defense responses to insects and fungi, systemic acquired resistance via salicylic acid signaling, response to wounding, UV-B, and cold, as well as jasmonic acid and oxylipin metabolism, glycoside breakdown, and embryo development. It is linked to vacuolar, cytosolic, and nuclear localization. Studies of related genes in other species connect the family to systemic acquired resistance, osmotic and salt stress tolerance, ABA sensitivity, spider mite resistance, and triterpene accumulation. The gene has also been associated with seed germination, NAD biosynthesis, and abiotic stress response.
