PAL — Cucumis sativus

Summary

CsPAL (CSA_4G008770) on cucumber chromosome 4 encodes a phenylalanine ammonia-lyase (EC 4.3.1.24). The gene is associated with L-phenylalanine breakdown, cinnamic acid anabolism, and regulation of flavonoid anabolism. It has been linked to lignin content, fruit color, and flavonoid content, as well as to net photosynthetic rate, chlorophyll content, plant height, root length, and abscisic acid content. Additional associations include cell wall thickening, pollen fertility, and protein content. The encoded protein localises to the cytoplasm and is connected to phenylpropanoid, salicylate, and suberin biosynthesis pathways. Studies of related genes in other species support the family’s central role in phenylpropanoid metabolism.
