PAL1 — Brassica oleracea

Summary

BoPAL1, located on chromosome 4 of cabbage (Brassica oleracea), encodes a phenylalanine ammonia-lyase, an enzyme with ammonia-lyase activity. This gene is associated with a wide range of biological processes, including the anabolism of anthocyanins, flavonoids, lignin, salicylic acid, jasmonic acid, melatonin, cinnamic acid and quinones, as well as the breakdown of L-phenylalanine, chlorophyll, lignin and ethene metabolism. BoPAL1 has been linked to agronomically important traits such as leaf colour, anthocyanin content, photosynthetic rate, soluble protein and amino acid content, and responses to UV light, freezing, salt stress, copper stress, drought recovery, and resistance to pathogens including Cucumber mosaic virus. It is also connected to herbicide resistance and cytokinin hypersensitivity. Studies of related genes in other species link the family to UV stress tolerance, herbivore defence and methyl salicylate production.
