PAL1 — Lactuca sativa

Summary

LSAT_V11C900484810, designated PAL1, is a gene on chromosome 9 of garden lettuce (Lactuca sativa). It encodes a phenylalanine ammonia-lyase, an enzyme with phenylalanine ammonia-lyase activity and amino acid binding, belonging to the Aromatic_Lyase and L-Aspartase-like domain families. The gene is associated with L-phenylalanine breakdown and cinnamic acid anabolism, and its product localises to the cytoplasm and macromolecular complexes. PAL1 has also been linked to shoot fresh weight. Studies of related genes in other species, including PAL1, PAL2, and PAL3, connect the family to the broader phenylpropanoid pathway, though these specific associations are not yet established in lettuce.
