PAL — Sorghum bicolor

Summary

SORBI_3006G148800 (SbPAL) on sorghum chromosome 6 encodes a protein with phenylalanine ammonia-lyase activity (EC 4.3.1.24), tyrosine ammonia-lyase activity, and ammonia-lyase activity. The gene is associated with L-phenylalanine breakdown, cinnamic acid anabolism, salicylic acid breakdown, lignin breakdown, and phenylpropanoid anabolism, and is linked to pathways including phenylpropanoid biosynthesis, salicylate biosynthesis, and suberin biosynthesis. It is associated with drought recovery, response to UV-B, response to oxidative stress, guard cell fate commitment, guard mother cell differentiation, and negative regulation of cytokinin mediated signalling. Associations also include IAA content, photosynthetic rate, and UV light sensitivity. Studies of related genes in other species connect the family to disease resistance, lignin deposition, flavonoid and anthocyanin accumulation, and tolerance to salt, freezing, and UV stress, as well as agronomic traits such as stem strength, forage yield, and seedling vigour.
