PAL — Cucumis sativus

Summary

CsPAL (CSA_6G405960) encodes a phenylalanine ammonia-lyase (EC 4.3.1.24) with ammonia-lyase and protein dimerization activities, and also exhibits DNA-binding transcription factor activity. The enzyme is associated with phenylpropanoid and salicylate biosynthesis, suberin biosynthesis, and primary metabolism. In cucumber, CsPAL is linked to lignin and salicylic acid breakdown, cinnamic acid anabolism, regulation of phenylpropanoid metabolism, drought recovery, induced systemic resistance, guard cell fate commitment, and responses to low humidity and UV light. The gene has been connected to disease resistance, virus resistance, chilling and freezing tolerance, salt stress tolerance, anthocyanin and flavonoid biosynthesis, and photosynthetic and respiration rates. Studies of related genes in other species link the PAL family to fruit shelf life, heat and drought tolerance, herbivore defense, and wound-induced suberization.
