2.A.7.4.8 USUALLY MULTIPLE AMINO ACIDS MOVE IN AND OUT TRANSPORTER (UMAMIT)
family proteiin, UMAMIT29 is a
glucosinolate exporters with a uniport mechanism. Loss-of-function
umamit29 umamit30 umamit31 triple mutants have a very low level of seed
glucosinolates, demonstrating a key role for these transporters in
translocating glucosinolates into seeds. The
UMAMIT uniporters facilitate glucosinolate efflux from biosynthetic
cells along the electrochemical gradient into the apoplast, where the
high-affinity H+-coupled glucosinolate importers GLUCOSINOLATE TRANSPORTERS (GTRs) load them into the phloem for translocation to the seeds (Xu et al. 2023).
