Sucrose -Mediated Transcriptional Regulation of Proton /Sucrose Symporters in Source Leaves of Sugar Beet and Arabidopsis Thaliana
… the evidence supports the hypothesis that a sucrose-mediated regulatory pathway common to at least two plant families acts as a key step in regulating assimilate partitioning by modulating phloem loading in response to changing levels of sink demand. Also, symporters that are members of two …

Molecular Characterization of Sugarcane Yellow Leaf Virus (SCYLV) and its Effect on Sucrose Transporters in Sugarcane Saccharum spp. hybrids
… proliferation rate of the virus in the plant. Sucrose is the main product of sugarcane, which accumulates in the stalk internodes in excess of 50 % of the dry weight. To gain an overview of the physiological status of SCYLV-infected sugarcane compared to virus-free plants, gene expression. …

The role of environment, sink capacity, and carbon translocation in determining C3 plant responses to elevated [CO2]
… method, apoplastic loading, uses active sugar transporters to load phloem, while another method, symplastic loading, uses passive diffusion along a sucrose gradient from leaf mesophyll cells to phloem. The hypothesis was that passive loaders, adapted to high mesophyll sucrose concentrations, …

Effects of Drought on Gene Expression in Maize Reproductive and Leaf Meristem Tissues as Revealed by Deep Sequencing
… carbohydrate metabolism, changes in starch and sucrose metabolism-related genes occurred in the ovary, consistent with a decrease in starch levels, and in sucrose transporter function, with no comparable changes occurring in the leaf meristem. ABA-related processes responded positively, but only …

Identification and characterization of factors involved in DNA demethylation and anti-silencing in Arabidopsis
… is based on 35S promoter driven <em>SUC2</em> (sucrose transporter 2) transgene, a mutant (<em>91-1</em>) was isolated and map-based cloning identified the responsible gene as <em>MBD7</em>(methyl-CpG binding protein 7). As important interpreters of DNA methylation, Methyl-CpG-Binding Domain …

Transposon Tagging in Strawberry and Potato and Characterization of Representative Strawberry Mutants
… deficiency due to T-DNA insertion near a sucrose transporter-2 gene showing stunted phenotype with increased level of anthocyanin was also characterized. The concentrations of sucrose, glucose, and fructose were significantly greater in source leaves of the mutant than wild type plants, …

Identification of a gene that makes-plants-gigantic-1: characterization of mpg1, a novel mutant of rice
… cassette that drives the overexpression of sucrose transport in rice phloem. The hypothesis simply suggested transporting more carbon (sucrose) from leaf tissue to heterotrophic tissues in the plant would increase the biomass of individual plants. Rice was used in these experiments because …

In situ studies of sugar metabolism in Ricinus communis L. and Saccharum officinarum L.
In order to find the sucrose efflux transporter of the endosperm of Ricinus communis L., the yeast complementation selection method was used, but it was unsuccessful. Mutation was occurred on the nSC4+ plasmid during the selection. Maybe the stress of the yeast cells was too strong and then induced …

Zur Bedeutung von Saccharose-Transportern in Pflanzen mit offener Phloemanatomie
… konnten aus A. meridionalis ein Saccharose-Transporter (AmSUT1) und aus A. barclaiana zwei Saccharose-Transporter (AbSUT1, AbSUT2) kloniert und charakterisiert werden. Diese Transportproteine sind Saccharose-H+-Symporter und besitzen nur eine geringe Hemmbarkeit durch den Inhibitor PCMBS. …
