Arabidopsis thaliana Tonoplast Monosaccharide Transporter
1 (AtTMT1) encodes a membrane protein, responsible
for transferring glucose from the plant cytosol into the vacuolar
compartment. Overexpression of AtTMT1 lead to an
expression of photosynthesis-related genes, reduced consumption of
sugars for cellular respiration, reduced nocturnal loss of CO2,
increased sugar export capacity from source leaves, increased the
biomass of Arabidopsis seeds, and accelerated early plant
development.
