GTR2 — Camelina sativa

Summary

CsGTR2 (CSA18G036110) encodes a glucosinolate:proton symporter belonging to the POT family and the major facilitator superfamily (MFS) of transmembrane transporters. The gene is associated with phloem glucosinolate loading and has been linked to glucosinolate accumulation, transport, and distribution, including in seeds. CsGTR2 is also associated with aphid resistance. The encoded protein localises to the membrane, plasmalemma, and plasmodesmata. Related genes in other species are linked to long-distance transport of aliphatic glucosinolates, and sequence similarity connections extend to nitrate uptake and aphid response traits.
