PAL — Triticum aestivum

Summary

TRAESCS6A02G222800 (PAL) on bread wheat chromosome 6A encodes a phenylalanine ammonia-lyase with tyrosine ammonia-lyase and ammonia-lyase activities, classified under EC 4.3.1.24. The gene is associated with phenylpropanoid metabolism, including cinnamic acid, salicylic acid, and lignin anabolism, as well as L-phenylalanine breakdown and protein homotetramerization. It has been linked to systemic acquired resistance, response to karrikin and nitrate, and transport processes such as transition metal, calcium, and proton transmembrane transport. Localization evidence places the product in the cytoplasm and macromolecular complexes. Trait associations include anther extrusion, pollen fertility, grain weight, anthocyanin content, heterosis, drought tolerance, and resistance to powdery mildew. Related genes in other species include PAL1, PAL2, PAL3, and PALB.
