PAL — Daucus carota subsp. sativus

Summary

DCAR_017697 (PAL1) on carrot chromosome 5 encodes a phenylalanine ammonia-lyase (EC 4.3.1.24), an enzyme with ammonia-lyase activity that also exhibits DNA-binding transcription factor activity and protein dimerization activity. The gene is associated with phenylpropanoid and anthocyanin biosynthesis, lignin breakdown, salicylic acid breakdown, and cinnamic acid anabolism. It has been linked to root color, anthocyanin content, UV light sensitivity, photosynthetic rate, and respiration rate. PAL1 is associated with disease resistance, pathogen and wound responses, chilling tolerance, salt stress tolerance, and freezing tolerance. It is also associated with guard cell fate commitment, drought recovery, response to low humidity, oxidative stress, and systemic acquired resistance. The protein localizes to the cytosol, cytoplasm, nucleus, and SCF complex, and participates in salicylate, suberin, and phenylpropanoid biosynthesis pathways.
