HST — Solanum tuberosum

Summary

PGSC0003DMG400011189 (HST) on potato chromosome 7 encodes a hydroxycinnamoyltransferase (HQT) with anthranilate N-benzoyltransferase, shikimate O-hydroxycinnamoyltransferase, rosmarinate synthase, and general acyltransferase activities, belonging to the CAT-like domain superfamily. This gene is associated with phenylpropanoid, flavonoid, anthocyanin, and lignin anabolism, as well as shikimate and secondary metabolism, wound healing, response to UV, systemic acquired resistance, and metabolic burst. It is also linked to hormone anabolism, nucleosome assembly, membrane fusion, pigmentation, and alkaloid metabolism. Associations with flavonoid and anthocyanin content have been noted. Studies of related genes in other species link the family to EC 2.3.1.133, 2.3.1.140, 2.3.1.144, and 2.3.1.302 activities.
