GST1 — Brassica oleracea var. botrytis

Summary

BoGST1 (BOLND125_C05P001800.1_BOLND125_V1) on cauliflower chromosome 5 encodes a glutathione S-transferase (GST) of the phi class, possessing glutathione transferase activity, glutathione binding, and metal ion binding capabilities. This gene is associated with responses to oxidative stress, hydrogen peroxide, cadmium, herbicides, and xenobiotic stimuli, as well as toxin breakdown and glutathione metabolism. BoGST1 is associated with defence responses against bacteria, fungi, and viruses, and with auxin signalling, salicylate response, and fruit ripening. Phenotypic associations include dehydration, salt, cold, and wounding stress responses, bacterial wilt resistance, resistance to Botrytis cinerea, camalexin biosynthesis, and herbicide response. The protein localises to the cytosol, plant-type cell wall, vacuole, plasmodesma, mitochondria, and stress granules. Related genes in other species link the family to heat, oxidative, and copper stress tolerance.
