PAL — Brassica juncea

Summary

BJUA05G07480S (BjPAL1) on Indian mustard chromosome A05 encodes a phenylalanine ammonia-lyase, an enzyme with ammonia-lyase activity. The gene is associated with the breakdown of L-phenylalanine and salicylic acid, cinnamic acid and anthocyanin anabolism, lignin breakdown, and regulation of phenylpropanoid, flavonoid, and secondary metabolism. It is linked to responses to UV-B, wounding, oxidative stress, photomorphogenesis, and circadian rhythm. Associations with agronomically relevant traits include seed color, photosynthetic rate, freezing tolerance, salt stress tolerance, herbicide resistance, and resistance to Cucumber mosaic virus and bacterial pathogens. The encoded protein localises to the cytosol and is linked to the SCF complex. Studies of related genes in other species connect the family to phenylalanine metabolism, UV stress resistance, and herbivore defense.
