PAL — Glycine max

Summary

GmPAL (GLYMA_20G180800V4) on soybean chromosome 20 encodes a phenylalanine ammonia-lyase, an enzyme with ammonia-lyase and amino-acid-binding activities. This gene is associated with the biosynthesis of lignin, anthocyanins, isoflavonoids, salicylic acid, cinnamic acid, and phytoalexins, as well as L-phenylalanine catabolism, the ascorbate-glutathione cycle, hydrogen peroxide signaling, detoxification, and biofilm formation. It has been linked to traits including lignin content, abscisic acid content, hydrogen peroxide content, root length, and plant height. The encoded protein localizes to the cytoplasm and macromolecular complexes. Studies of related genes in other species connect the family to drought tolerance, seed dormancy, chlorophyll content, transpiration rate, and sugar content.
