Degradation of chlorinated volatile organic compounds from contaminated ground water using a carrier-bound TiO/UV/O-system.

In the present work, a suitable experimental setup was developed to successfully apply advanced oxidation processes (AOP) to real groundwater matrices. This setup combines an O-bubble column reactor with a carrier-bound TiO/UV-system. The degradation of various chlorinated ethene and methane derivatives commonly found of chlorinated volatile organic compound polluted regional groundwater samples was investigated.

Hydrogen peroxide-assisted photocatalytic water treatment for the removal of anthropogenic trace substances from the effluent of wastewater treatment plants.

Supported titanium dioxide catalysts were used in a photocatalytic flat cell reactor to remove organic micropollutants from real wastewater. Catalysts based on stainless steel mesh with a porous coating made of titanium dioxide nanoparticles with predominantly anatase modification were used. The influence of the retention time, and light output, and the effect of hydrogen peroxide on the degradation were examined.

Rice pyramided line IRBB67 (Xa4/Xa7) homeostasis under combined stress of high temperature and bacterial blight.

Rice bacterial blight (BB) caused by Xanthomonas oryzae pv. oryzae (Xoo) implies substantial yield loss to rice. In times of climate change, increasing temperatures are observed and further acceleration is expected worldwide.

Broad-spectrum resistance to bacterial blight in rice using genome editing.

Bacterial blight of rice is an important disease in Asia and Africa. The pathogen, Xanthomonas oryzae pv. oryzae (Xoo), secretes one or more of six known transcription-activator-like effectors (TALes) that bind specific promoter sequences and induce, at minimum, one of the three host sucrose transporter genes SWEET11, SWEET13 and SWEET14, the expression of which is required for disease susceptibility.

Rapid identification of inflorescence type markers by genotyping-by-sequencing of diploid and triploid F plants of Hydrangea macrophylla.

Background: The ornamental crop Hydrangea macrophylla develops highly attractive lacecap (wild type) or mophead inflorescences. The mophead trait, which is mostly favored by consumers, is recessively inherited by the INFLORESCENCE TYPE locus (INF). If lacecap cultivars are crossed with mophead cultivars, then either 50% or all progenies develop lacecap inflorescences, depending on the zygosity at the INF locus.

Metallic iron for safe drinking water provision: Considering a lost knowledge.

Around year 1890, the technology of using metallic iron (Fe) for safe drinking water provision was already established in Europe. The science and technology to manufacture suitable Fe materials were known and further developed in this period. Scientists had then developed skills to (i) explore the suitability of individual Fe materials (e.

High temperature effects on Pi54 conferred resistance to Magnaporthe oryzae in two genetic backgrounds of Oryza sativa.

The global temperatures are predicted to rise due to climate change. However, knowledge on the mechanisms underlying the effect of high temperature (HT) on plant pathogen interaction is limited. We investigated the effect of elevated temperature on host phenotypic, biochemical and gene expression patterns in the rice-Magnaporthe oryzae (Mo) pathosystem using two genetic backgrounds, Co39 (Oryzae sativa-indica) and LTH (O.

Elevated temperature increases in planta expression levels of virulence related genes in Magnaporthe oryzae and compromises resistance in Oryza sativa cv. Nipponbare.

Temperature changes have the potential to alter the incidence and severity of plant disease epidemics and pressures, as well as to reshape the co-evolutionary relationships between plants and pathogens. However, the molecular basis of temperature modulation of pathogenicity of plant pathogens is still unclear. Here, we studied the effect of temperature on biomass of Magnaporthe oryzae in planta using qPCR.

High Temperature Enhances the Resistance of Cultivated African Rice, Oryza glaberrima, to Bacterial Blight.

Rice bacterial blight (BB) is caused by Xanthomonas oryzae pv. oryzae and is responsible for substantial yield loss worldwide. Host resistance remains the most feasible control measure.
