THT4 — Solanum tuberosum

Summary

PGSC0003DMG400014778 (symbol THT4, also known as StTHT4 or StCASHT) on potato chromosome 8 encodes a tyramine hydroxycinnamoyl transferase with N-acetyltransferase activity. The gene is associated with cell wall thickening, salicylic acid anabolism, systemic acquired resistance, and virus-induced post-transcriptional gene silencing. It has also been linked to primary metabolism, fatty acid metabolism, flavonoid anabolism, and nitric oxide storage. The encoded protein localises to the cytoplasm. Studies of related genes in other species link the family to pungency and leaf curling traits, though these associations are not established for potato.
