PAL — Lactuca sativa

Summary

LsPAL, encoded by the garden lettuce gene LSAT_V11C600310190 on chromosome 6, is a phenylalanine ammonia-lyase, an enzyme with ammonia-lyase activity. This gene is associated with the breakdown of salicylic acid and L-phenylalanine, the anabolism of cinnamic acid and phenylpropanoids, and the regulation of phenylpropanoid metabolism. It has been linked to responses to UV-B, oxidative stress, wounding, low humidity, and drought recovery, as well as to guard cell fate commitment and differentiation. Associations with traits include photosynthetic rate, shoot fresh weight, and UV light sensitivity. The gene is also linked to disease resistance, anthocyanin accumulation, lignin and flavonoid biosynthesis, and tolerance to chilling, freezing, salt, and copper stress.
