High impact information on SUT2

PmSUC3: characterization of a SUT2/SUC3-type sucrose transporter from Plantago major [1].
For several plant species, it has been shown that at least one of these genes (e.g., AtSUC3 in Arabidopsis and LeSUT2 in tomato) differs from all other family members in several features, such as the length of the open reading frame, the number of introns, and the codon usage bias [1].
SUT2, a putative sucrose sensor in sieve elements [2].
The SUT2 gene maps on chromosome V of potato and is linked to a major quantitative trait locus for tuber starch content and yield [2].
In contrast to LeSUT1, which is induced during the sink-to-source transition of leaves, SUT2 is more highly expressed in sink than in source leaves and is inducible by sucrose [2].

Biological context of SUT2

The cDNA corresponding to the open reading frame T17M13.3 from Arabidopsis chromosome II was isolated and the encoded protein was characterized as a member of a subgroup of higher plant sucrose transporters [3].
