PAL1 — Pisum sativum

Summary

PsPAL1 (PSAT2G001960) on garden pea chromosome 2LG1 encodes a phenylalanine ammonia-lyase, an enzyme with phenylalanine ammonia-lyase activity that also exhibits protein dimerization activity and DNA-binding transcription factor activity. The gene is associated with the breakdown of L-phenylalanine and salicylic acid, cinnamic acid and phenylpropanoid anabolism, lignin breakdown, and regulation of phenylpropanoid metabolism. It is linked to responses to UV-B, oxidative stress, low humidity, and drought recovery, as well as guard cell fate commitment, guard mother cell differentiation, pollen development, and negative regulation of cytokinin-mediated signalling. The encoded protein localises to the cytosol, cytoplasm, nucleus, and SCF complex. Associations include photosynthetic rate, respiration rate, UV light sensitivity, and numerous traits such as disease resistance, anthocyanin and flavonoid biosynthesis, lignin content, salt and freezing tolerance, and pathogen resistance.
