PAL — Cucumis sativus

Summary

CsPAL (CSA_6G445750) encodes a phenylalanine ammonia-lyase (EC 4.3.1.24) with phenylalanine ammonia-lyase activity, protein dimerization activity, and DNA-binding transcription factor activity. This cucumber gene on chromosome 6 is associated with phenylpropanoid biosynthesis, salicylate biosynthesis, suberin biosynthesis, and secondary metabolism. It has been linked to lignin content, fruit firmness, fruit color, carotenoid content, chlorophyll content, photosynthetic rate, plant height, stem thickness, root weight, seedling vigor, and leaf relative water content. Associations also include disease resistance, virus resistance, wound response, anthocyanin accumulation, chilling tolerance, salt stress tolerance, UV-B tolerance, freezing tolerance, and responses to abiotic stresses including copper and magnetic field exposure. The gene is connected to sex determination, pigment accumulation, and salicylic acid breakdown. Studies of related genes in other species link the family to drought tolerance, heat tolerance, herbivore defense, and fruit shelf life.
