PAL1 — Phaseolus vulgaris

Summary

PHAVU_008G289500, designated PvPAL1, encodes a phenylalanine ammonia-lyase (PAL) on French bean chromosome 8. The product possesses ammonia-lyase and phenylalanine ammonia-lyase activities, protein dimerization activity, and DNA-binding transcription factor activity. PvPAL1 is associated with L-phenylalanine and salicylic acid breakdown, cinnamic acid and anthocyanin anabolism, lignin breakdown, regulation of phenylpropanoid metabolism, drought recovery, response to UV-B, oxidative stress, and low humidity, guard cell fate commitment, and negative regulation of cytokinin-mediated signalling. It localises to the cytosol, cytoplasm, nucleus, and SCF complex. The gene is linked to traits including nitrogen recycling, photosynthetic and respiration rates, cellulose content, UV sensitivity, and numerous phenotypes such as pathogen resistance, salt and freezing tolerance, anthocyanin and lignin biosynthesis, and herbicide response. Related genes in other species connect it to UV stress tolerance, stomatal development, and herbivore defence.
