GTR1 — Brassica juncea

Summary

BjGTR1 (BJUB08G11970S) on chromosome B08 of Indian mustard (Brassica juncea) encodes a member of the POT family and the major facilitator superfamily, with glucosinolate:proton symporter activity. The gene is associated with phloem glucosinolate loading, glucosinolate anabolism, and defense response. Its product localises to the plasma membrane, Golgi complex, plasmodesma, cytosol, and nucleus. BjGTR1 is associated with glucosinolate distribution and accumulation, including in seeds, as well as with aphid resistance, wound response, anther dehiscence, stamen development and filament elongation, fertility, lateral root development, and transport of gibberellic acid and jasmonoyl-L-isoleucine. Related genes in other species are linked to glucosinolate transport and long-distance transport of aliphatic glucosinolates, as well as to phytohormone transport.
