PAL — Cucumis melo

Summary

MELO3C025786.2, symbol PAL and also known as CmPAL, encodes a phenylalanine ammonia-lyase (EC 4.3.1.24) on melon chromosome 12. The product belongs to the Phe_NH3-lyase and aromatic lyase families and exhibits phenylalanine ammonia-lyase activity and amino acid binding. In melon, this gene is associated with L-phenylalanine breakdown, cinnamic acid and phenylpropanoid anabolism, flavonoid metabolism, and salicylate and suberin biosynthesis. It has been connected to fruit and stamen development, cold acclimation, chlorophyll fluorescence, detoxification, endocytosis, and meiosis. Localisation evidence links the product to the cytoplasm and macromolecular complexes. The gene is also associated with sucrose content. Studies of related genes in other species further connect the family to phenylpropanoid metabolism.
