Rice Transcription Factor OsDOFll Modulates Sugar Transport by Promoting Expression of Sucrose Transporter and SWEET Genes

Sucrose is produced in mesophyll cells and transferred into phloem cells before it is delivered long- distance to sink tissues. However, little is known about how sucrose transport is regulated in plants. Here, we identified a T-DNA insertional mutant of Oryza sativa DNA BINDING WITH ONE FINGER 11 （OsDOF11）, which is expressed in the vascular cells of photosynthetic organs and in various sink tissues. The osdofll mutant plants are semi-dwarf and have fewer tillers and smaller panicles as compared with wild-type （WT） plants. Although sucrose enhanced root elongation in young WT seedlings, this enhance- ment did not occur in osdof11 seedlings due to reduced sucrose uptake. Sugar transport rate analyses revealed that less sugar was transported in osdofll plants than in the WT. Expression of four Sucrose Transporter （SUT） genes-OsSUT1, OsSUT3, OsSUT4, and OsSUT5-as well as two Sugars Will Eventually be Exported Transporters （SWEET） genes, OsSWEETll and OsSWEET14, was altered in various organs of the mutant, including the leaves. Chromatin immunoprecipitation assays showed that OsDOFll directly binds the promoter regions of SUT1, OsSWEETll, and OsSWEET14, indicating that the expression of these transporters responsible for sucrose transport via apopiastic loading is coordinately controlled by OsDOFll. We also observed that osdofll mutant plants were less susceptible to infection byXanthomonas oryzae pathovar oryzae, suggesting that OsDOFll participates in sugar distribution during pathogenic in- vasion. Collectively, these results suggest that OsDOFll modulates sugar transport by regulating the expression of both SUT and SWEET genes in rice.

Role of rice cytosolic hexokinase OsHXK7 in sugar signaling and metabolism

引用

Journal of Integrative Plant Biology 2016年第2期58卷 127-135页

We characterized the function of the rice cytosolic hexokinase OsHXK7 （Qryza sativa HexokindseZ）, which is highly upregulated when seeds germinate under O2- deficient conditions. According to transient expression assays that used the promoter：luciferase fusion construct, OsHXK7 enhanced the glucose （Glc）-dependent repression of a rice n-amylase gene （RAmy3D） in the mesophyll protoplasts of maize, but its catalytically inactive mutant alleles did not. Consistently, the expression of OsHXK7, but not its catalytically inactive alleles, complemented the Arabidopsis glucose insensitive2-1 （gin2-1） mutant, thereby resulting in the wild type characteristics of Glc-dependent repression, seedling development, and plant growth. Interestingly, OsHXK7-mediated Glc-dependent repression was abolished in the O2-deficient mesophyll protoplasts of maize. This result provides compelling evidence that OsHXK7 functions in sugar signaling via a glycolysis-dependent manner under normal conditions, but its signaling role is suppressed when O2 is deficient. The germination of two null OsHXK7 mutants, oshxk7-1 and oshxk7-2, was affected by O2 deficiency, but overexpression enhanced germination in rice. This result suggests the distinct role that OsHXK7 plays in sugar metabolism and efficient germination by enforcing glycolysis-mediated fermentation in O2-deficient rice.

Dear Editor, During CO2 assimilation, the reductive pentose phos- phate cycle generates triose phosphates （triose-P） at the expense of ATP and NADPH generated by photosynthetic light reactions. Triose-P is retained within chloroplasts to either regenerate the CO2 acceptor ribulose-l,5-bi- sphosphate or to feed into transitory starch synthesis. Alternatively, triose-P can be exported into the cytosol to produce sucrose. To maintain optimum rates of photo- synthesis, the rate of triose-P export from the chloroplast stroma to the cytosol is necessarily adjusted to the demands for photoassimilate export. The triose-P/phosphate （Pi） translocator （TPT） mediates the export of stromal triose-P into the cytosol in a counter exchange for cytosolic Pi.

The electro-clean system (ECS), a ballast water management system that eliminates harmful aquatic organisms in ship ballast water via electrochemically produced chloride, was developed. The current density for potentiostatic experiments subjected to seawater with an applied potential (-0.1 V) at various TRC concentrations (2×10-6, 6×10-6, 10×10-6, and 15×10-6) have similar results. The current density at -0.1 V has the highest value compared with that at -0.7 V and -0.4 V. For all concentrations, the current density increases with increasing applied potential.

Optimal treatment strategy for Helicobacter pylori:Era of antibiotic resistance

引用

World Journal of Gastroenterology 2014年第19期20卷 5654-5659页

作者： Jun Heo seong Woo jeon Department of Internal Medicine Kyungpook National University Hospital Medical CenterDaegu 702-911South Korea

Standard triple therapy, consisting of a proton pump inhibitor, plus amoxicillin and clarithromycin, has been the most commonly used first-line treatment regimen for Helicobacter pylori (H. pylori) eradication for many years worldwide. However, as a result of increased resistance to antibiotics, H. pylori eradication rates with use of standard triple therapy have been declining and recently reached < 80% in many countries. Several new strategies to enhance the eradication rate of H. pylori have been studied. Currently, among the alternative first-line eradication regimens, concomitant and hybrid regimens have shown excellent results and could be the optimal treatment option. Although clinical usefulness of rescue therapy for patients in whom eradication of H. pylori with non-bismuth quadruple regimen has failed is unclear, levofloxacin-based quadruple therapy has shown promise as a rescue treatment. The choice of third-line therapy depends on factors such as the local pattern of antibiotic resistance, drug availability, and previous treatment. We hope that a simple method for detection of antibiotic susceptibility using polymerase chain reaction would be a possible alternative to administration of “tailored treatment” in the era of increasing prevalence of antimicrobial resistance.
