PAL — Cicer arietinum

Summary

AhPAL, located on chickpea chromosome 19, encodes a phenylalanine ammonia-lyase. The gene is associated with L-phenylalanine breakdown, cinnamic acid and anthocyanin anabolism, and the regulation of phenylpropanoid metabolism. It is linked to drought recovery, response to oxidative stress, low humidity, and UV light sensitivity. Associations also include traits such as leaf relative water content, photosynthetic rate, chlorophyll content, shoot and root dry weight, and sugar and fructose content. The gene is connected to isoflavonoid phytoalexin anabolism, lignin breakdown, and salicylic acid breakdown. Studies of related genes in other species link the family to UV stress tolerance, root hair patterning, and chlorogenic acid accumulation.
