Plant physiology: The importance of sucrose transporters
نویسنده
چکیده
Sucrose transport is essential for the distribution of carbohydrates in plants. Recent studies have shown that a specific transporter protein plays an essential role in loading sucrose into the phloem component of the plant vasculature.

How sweet it is: identification of vacuolar sucrose transporters.
Vacuoles have diverse functions within all plant cells. Vacuoles get rid of wastes, accumulate nutrients, and regulate pressure within a cell. They are also known to store sugars. Many of the compounds within vacuoles are actively transported across the tonoplast membrane against a concentration gradient via transporters. The identification of transporters involved in vacuolar Suc transport was...
متن کاملApple sucrose transporter SUT1 and sorbitol transporter SOT6 interact with cytochrome b5 to regulate their affinity for substrate sugars.
Sugar transporters are central machineries to mediate cross-membrane transport of sugars into the cells, and sugar availability may serve as a signal to regulate the sugar transporters. However, the mechanisms of sugar transport regulation by signal sugar availability remain unclear in plant and animal cells. Here, we report that a sucrose transporter, MdSUT1, and a sorbitol transporter, MdSOT6...

Hydroponically grown ten grape genotypes (Vitis vinifera L.) were treated with different concentrations of NaCl. Chawga genotype accumulated K+ in its root and shoot even at high salinity. The correlation between Na+ and K+ concentrations in root and lamina of all genotypes was negative (P
متن کاملSucrose importation into laticifers of Hevea brasiliensis, in relation to ethylene stimulation of latex production.
BACKGROUND AND AIMS The major economic product of Hevea brasiliensis is a rubber-containing cytoplasm (latex), which flows out of laticifers (latex cells) when the bark is tapped. The latex yield is stimulated by ethylene. Sucrose, the unique precursor of rubber synthesis, must cross the plasma membrane through specific sucrose transporters before being metabolized in the laticifers. The relati...
متن کاملMicroarray analysis of gene expression patterns in Arabidopsis seedlings under trehalose, sucrose and sorbitol treatment
Trehalose is the non-reducing alpha-alpha-1, 1-linked glucose disaccharide. The biosynthesisprecursor of trehalose, trehalose-6-phosphate (T6P), is essential for plant development, growth,carbon utilization and alters photosynthetic capacity but its mode of action is not understood. In thecurrent research, 6 days old seedlings of Arabidopsis thaliana (Columbia ecotype) were grown inliquid cultu...
