PAL — Cucumis sativus

Summary

CsPAL (CSA_6G147460) in cucumber encodes a phenylalanine ammonia-lyase (EC 4.3.1.24), an enzyme with phenylalanine ammonia-lyase activity that also exhibits amino acid binding, protein dimerization, and DNA-binding transcription factor activity. The gene is associated with phenylpropanoid and salicylate biosynthesis, suberin biosynthesis, and secondary metabolism. It has been linked to diverse biological processes including lignin breakdown, cinnamic acid anabolism, salicylic acid breakdown, drought recovery, guard cell fate commitment, and induced systemic resistance. Associations with traits include photosynthetic rate, respiration rate, and UV light sensitivity. The gene is also connected to disease resistance, virus resistance, anthocyanin accumulation, flavonoid and lignin biosynthesis, and freezing tolerance. Studies of related genes in other species link the family to fruit shelf life, heat tolerance, drought tolerance, pathogen resistance, and floral scent production.
