Representative single-plane confocal imaging of 5-week-old leaves from stable Arabidopsis lines transformed with pGTR1(2 kb)-GTR1(genomic fragment)-yellow fluorescent protein (YFP; Venus)-GTR1_3′ untranslated region (UTR; 0.3 kb) (seven independent lines) or pGTR2(2 kb)-GTR2 (genomic fragment)-mORANGE-GTR2_3′ UTR (0.3 kb) (22 independent lines). Representative mesophyll cells are shown for GTR1 and representative phloem-associated cells are shown for GTR2. Arrows indicate plasma-membrane localization. Scale bars, 25 μm.

Summary:
Two high-affinity proton-dependent transporters of glucosinolates have been identified in Arabidopsis and termed GTR1 and GTR2; these transporters are essential for transporting glucosinolates to seeds, offering a means to control the allocation of defence compounds in a tissue-specific manner, which may have agricultural biotechnology implications.
