PAL1 — Solanum tuberosum

Summary

StPAL1 (PGSC0003DMG402021549) on potato chromosome 9 encodes a phenylalanine ammonia-lyase (EC 4.3.1.24) with ammonia-lyase and protein dimerization activities. The gene is associated with heat tolerance, drought tolerance, wound-induced suberization, chemical defense, and disease resistance responses including bacterial resistance. It is linked to phenylpropanoid, flavonoid, anthocyanin, lignin, and salicylic acid biosynthesis, as well as cinnamic acid and phytoalexin production. Associations extend to traits such as starch, sucrose, carbohydrate, anthocyanin, flavonoid, and lignin content, along with photosynthetic rate, plant height, leaf number, and relative growth rate. The protein localizes to the cytosol, cytoplasm, and nucleus. Studies of related genes in other species connect the family to pathogen resistance, UV stress tolerance, and fruit shelf life.
