GTR1 — Camelina sativa

Summary

CsGTR1 (CSA09G048490) on Camelina sativa chromosome 9 encodes a glucosinolate:proton symporter belonging to the POT family and the major facilitator superfamily, with transmembrane transporter activity. The gene is associated with phloem glucosinolate loading and localises to multiple cellular compartments including the Golgi, plasmodesmata, plasma membrane, cytosol and nucleus. CsGTR1 is associated with glucosinolate distribution and accumulation, particularly in seeds, as well as with anther dehiscence, stamen development and filament elongation, fertility, lateral root development, aphid resistance, wound response, and jasmonate signalling. It is also linked to transport of gibberellic acid and jasmonoyl-L-isoleucine. Studies of related genes in other species connect the family to phytohormone transport and long-distance transport of aliphatic glucosinolates.
