GST1 — Brassica oleracea var. botrytis

Summary

BoGST1, located on chromosome 8 of cauliflower (Brassica oleracea var. botrytis), encodes a glutathione S-transferase (GST) with glutathione transferase activity, capable of binding glutathione, quercitrin, camalexin, copper, and cobalt ions, and it forms homodimers. This gene is associated with responses to xenobiotic stimuli, herbicides, oxidative stress, hydrogen peroxide, cadmium, viruses, bacteria, and fungi, as well as with toxin breakdown, glutathione metabolism, auxin signaling, fruit ripening, and dehydration response. It has been linked to salt stress tolerance, cold stress response, wounding response, bacterial wilt resistance, resistance to Botrytis cinerea, and camalexin production. The encoded protein localizes to the cytosol, cytoplasm, plant-type cell wall, vacuole, plasmodesma, mitochondria, stress granules, and extracellular space. Studies of related genes in other species link the family to heat, oxidative, and metal stress tolerance.
