APIC — Brassica juncea

Summary

BJUA10G01390S (APIC, also known as BjGST1) encodes a glutathione S-transferase (GST) belonging to the phi class, as indicated by its GST_Phi_C and GST_C domains. The enzyme exhibits glutathione transferase activity and binds glutathione, quercitrin, camalexin, copper, and cobalt ions. This gene is associated with detoxification, toxin breakdown, and glutathione metabolism, as well as responses to oxidative stress, hydrogen peroxide, cadmium, herbicides, and xenobiotic stimuli. It is linked to defence responses against bacteria and fungi, auxin signalling, and the metabolic burst. The encoded protein localises to the cytosol, plant-type cell wall, vacuole, plasmodesmata, mitochondria, and stress granules. Phenotypic associations include salt stress tolerance, dehydration response, bacterial wilt resistance, resistance to Botrytis cinerea, camalexin production, and plant growth. Studies of related genes in other species link the family to heat, oxidative, and metal toxicity tolerance.
