PAL — Capsicum annuum

Summary

CaPAL (T459_30765) on pepper chromosome 12 encodes a phenylalanine ammonia-lyase (EC 4.3.1.24) with ammonia-lyase and amino acid binding activities, and also possesses DNA binding transcription factor activity. The enzyme is associated with L-phenylalanine and salicylic acid breakdown, cinnamic acid and phenylpropanoid anabolism, lignin breakdown, and negative regulation of cytokinin signalling. It has been linked to fruit ripening, circadian rhythm, drought recovery, UV-B response, oxidative stress response, guard cell fate commitment, and low humidity response. Associations include disease tolerance, resistance to pathogens including Corynespora cassiicola and Cucumber mosaic virus, anthocyanin and flavonoid biosynthesis, chilling and freezing tolerance, salt stress tolerance, wound response, and photosynthetic and respiration rates. The protein localises to the cytosol, nucleus, and SCF complex, and participates in salicylate, phenylpropanoid, and suberin biosynthesis pathways.
