PAL — Cucumis sativus

Summary

CsPAL (CSA_6G445760) on cucumber chromosome 6 encodes a phenylalanine ammonia-lyase (EC 4.3.1.24) with phenylalanine ammonia-lyase activity, protein dimerization activity, and DNA-binding transcription factor activity. The enzyme is associated with phenylpropanoid and salicylate biosynthesis, suberin biosynthesis, and primary metabolism. It has been linked to lignin, flavonoid, and anthocyanin biosynthesis, as well as salicylic acid and cinnamic acid metabolism. The gene is associated with disease resistance, including resistance to Corynespora cassiicola, bacterial and viral pathogens, and induced systemic resistance. It is also associated with abiotic stress responses such as chilling tolerance, freezing tolerance, salt stress tolerance, UV light sensitivity, drought recovery, and response to low humidity. Additional associations include photosynthetic rate, respiration rate, guard cell fate commitment, and structural development. Studies of related genes in other species link the family to fruit shelf life, heat tolerance, drought tolerance, and herbivore defense.
