Understanding and manipulating sucrose phloem loading, unloading, metabolism, and signalling to enhance crop yield and food security
Sucrose is produced in, and translocated from, photosynthetically active leaves (sources) to
support non-photosynthetic tissues (sinks), such as developing seeds, fruits, and tubers …

Sugar transporters in plants and in their interactions with fungi
Sucrose and monosaccharide transporters mediate long distance transport of sugar from
source to sink organs and constitute key components for carbon partitioning at the whole …

Reimport of carbon from cytosolic and vacuolar sugar pools into the Calvin–Benson cycle explains photosynthesis labeling anomalies
When isotopes of carbon are fed to photosynthesizing leaves, metabolites of the Calvin–
Benson cycle (CBC) are rapidly labeled initially, but then the rate of labeling slows …

SWEET17, a facilitative transporter, mediates fructose transport across the tonoplast of Arabidopsis roots and leaves
Fructose (Fru) is a major storage form of sugars found in vacuoles, yet the molecular
regulation of vacuolar Fru transport is poorly studied. Although SWEET17 (for SUGARS …
