ARA8 — Brassica juncea
Summary
BJUB02G50940S (BjARA8, also known as BjPCS1) on chromosome B02 of Indian mustard encodes a phytochelatin synthase, a papain-like cysteine peptidase family member with glutathione gamma-glutamylcysteinyltransferase activity. The enzyme is associated with phytochelatin anabolism, arsenite transport, and cellular detoxification of cadmium and copper ions. It is linked to indole glucosinolate breakdown, defense response by callose deposition, response to arsenic and cadmium, stress response, and defence against bacteria. The protein localises to plastid and cytosol. Associations with auxin content, immune signaling, osmotic stress tolerance, and arsenic translocation have been noted. Studies of related genes in other species link the family to heavy metal tolerance and accumulation, pathogen resistance, callose deposition, and stem lignification.
