PAL — Cucumis sativus

Summary

CsPAL (CSA_6G446290) 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. It belongs to the Phe_NH3-lyase and aromatic lyase families. The gene is associated with phenylpropanoid and salicylate biosynthesis, suberin biosynthesis, and primary metabolism. It is linked to lignin, flavonoid, and anthocyanin biosynthesis, as well as disease resistance, virus resistance, wound response, and defense responses. Associations also include abiotic stress responses such as chilling tolerance, freezing tolerance, salt stress tolerance, UV-B tolerance, drought recovery, and copper stress response. The product localizes to the cytosol, cytoplasm, nucleus, and SCF complex. Studies of related genes in other species connect the family to fruit shelf life, heat tolerance, drought tolerance, pathogen resistance, and floral scent production.
