PAL1 — Arabidopsis thaliana

Summary

AT2G37040 (PAL1) encodes a protein with phenylalanine ammonia-lyase activity (EC 4.3.1.24) and belongs to the Phe_NH3-lyase family. In Arabidopsis thaliana, PAL1 is associated with herbivore defense, methyl salicylate production, UV stress resistance, hypertonic stress response, and with lignin, anthocyanin, salicylic acid, phytoalexin, and suberin biosynthesis, as well as responses to UV-B, wounding, pathogen resistance, and drought recovery. It is linked to cell wall thickening, pigmentation, dehiscence, and negative regulation of cytokinin signalling. It localises to the cytosol, nucleus, and SCF complex. Studies of related genes in other species associate the family with additional traits including fruit shelf life, heat and drought tolerance, virus resistance, and root development.
