In this study I provide evidence of biological nitrogen fixation by endophytic, diazotrophic bacteria as a possible source of nitrogen for lodgepole pine (Pinus contorta var. latifolia (Dougl. Engelm.) and western redcedar (Thuja plicata Donn.); conifers that are known for their ability to grow in nitrogenpoor forests of western North America. Diazotrophic bacteria were isolated from root ...

This study reveals that a peroxisomal BZU1/ACN1mediated acetate–malate shunt produces malate, an osmotically active solute and/or signaling molecule, to regulate the turgor pressure of guard cells, thereby controlling guard cell opening and regulating drought resistance in Arabidopsis.

A dual carcinoembryonic antigen (CEA) biosensing alternative optoelectric platforms has been developed based on gold modified ITO electrode. The new platform is constructed by assembly of a thiolderivativenanogold (TDN) labeled antiCEA (TDNantiCEA) antibody on a gold/indium tin oxide (ITO) electrode to create a high CEA sensitive surface.

After evaluation of the fineness of the grind, the solvents were added to the mixture under vigorous stirring. Nonphotocatalytic coatings were prepared in a similar manner without TiO 2 nanoparticles and used as reference coatings in the investigation. The pigment volume concentration (PVC) of the coatings is defined in this work according to Eq.
