Abstract Here, we report that SUGARS WILL EVENTUALLY BE EXPORTED TRANSPORTER (SWEET16) from Arabidopsis (Arabidopsis thaliana) is a vacuole-located carrier, transporting glucose (Glc), fructose (Fru), and sucrose (Suc) after heterologous expression in Xenopus laevis oocytes. The SWEET16 gene, similar to the homologs gene SWEET17, mainly expressed vascular parenchyma cells. Application of Glc, Fru, or Suc, as well cold, osmotic stress, low nitrogen, provoke down-regulation messenger RNA...
Sucrose (Suc) is one of the most important types sugars in plants, serving inter alia as a long-distance transport molecule, carbon and energy storage compound, an osmotically active solute, fuel for many anabolic reactions. Suc biosynthesis degradation pathways are well known; however, regulation intracellular distribution poorly understood. In particular, cellular function chloroplast reserves transporters involved accumulating these substantial levels remain uncharacterized. Here, we...
Summary Arabidopsis vacuoles harbor, besides sugar transporter of the TMT ‐type, an early response to dehydration like 6 ( ERDL 6) protein involved in glucose export into cytosol. However, mode transport and plant's feedback overexpression its activity on essential properties such as, for example, seed germination or freezing tolerance, remain unexplored. Using patch‐clamp studies expressing At we demonstrated directly that this carrier operates as a proton‐driven exporter. Overexpression Bv...
