HS1 — Beta vulgaris subsp. vulgaris

Summary

BvHS1 (BVRB_3G050060) on sugar beet chromosome 3 encodes a Dabb/HS1/DABB1-like dimeric α/β-barrel domain protein with cyclase and lyase activities and metal-binding capacity. The gene is associated with terpenoid, olivetolic acid and cannabinoid anabolism, pollen tube adhesion, homologous recombination, and defence responses to bacteria and fungi. Its product localises to the cytosol, cytoplasm and plasma membrane. Related genes in other species link the family to antimicrobial activity and stress responses, and to the enzyme 4.4.1.26 and traits including stomatal opening and oxidative stress response.
