PAL — Solanum lycopersicum

Summary

Solyc05g056170, designated PAL1 on tomato chromosome 5, encodes a phenylalanine ammonia-lyase (PAL) with ammonia-lyase activity and belongs to the aromatic lyase family. PAL1 is associated with L-phenylalanine and salicylic acid breakdown, cinnamic acid and pigment anabolism, regulation of flavonoid and phenylpropanoid metabolism, wound healing, drought recovery, and the shikimate pathway. It is linked to fruit shelf life, disease resistance, pathogen and wound responses, anthocyanin accumulation, and tolerance to UV-B, chilling, freezing, salt, and copper stress. Associations also extend to traits such as lycopene, flavonoid, starch, and neoxanthin content, photosynthetic rate, plant height, stem diameter, and leaf angle. The protein localizes to the cytosol, cytoplasm, and nucleus.
