PAL — Brachypodium distachyon

Summary

BdPAL (BRADI_3G47120V3) on Brachypodium distachyon chromosome 3 encodes a phenylalanine ammonia-lyase (EC 4.3.1.24) with tyrosine ammonia-lyase activity, ammonia-lyase activity, amino acid binding, protein dimerization activity, and DNA-binding transcription factor activity. It belongs to the Phe_NH3-lyase and aromatic lyase families. This gene is associated with phenylpropanoid, lignin, salicylic acid, cinnamic acid, and ethylene biosynthesis, as well as salicylic acid and lignin breakdown. It is linked to drought recovery, guard cell fate commitment, guard mother cell differentiation, and negative regulation of cytokinin-mediated signaling. Associations include IAA content, photosynthetic rate, UV light sensitivity, pathogen resistance, salt stress tolerance, freezing tolerance, and herbicide resistance. Studies of related genes in other species connect the family to traits such as stem strength, forage yield, bacterial blight resistance, and aluminum tolerance.
