PAL — Cucumis sativus

Summary

CSA_4G008250 (PAL) on cucumber chromosome 4 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 gene is associated with the phenylpropanoid biosynthesis pathway, salicylate and suberin biosynthesis, and secondary metabolism. It has been linked to lignin content, anthocyanin accumulation, and flavonoid biosynthesis, as well as responses to UV light, low temperature, salt stress, copper stress, and powdery mildew disease. Associations also include adventitious root development, photosynthetic rate, respiration rate, and disease tolerance. Studies of related genes in other species connect the PAL family to pathogen resistance, herbivore defense, drought tolerance, heat tolerance, wound-induced suberization, floral scent production, and fruit shelf life.
