Soybean [Glycine max (L.) Merri.] is an important oilseed and food crop. In recent years, environmental degradation has accelerated soil alkalization, salinization, water deficit, which have seriously threatened the soybean quality yield. Chaperone DNAJ proteins play roles in plant response to a number of abiotic biotic stresses. Here, we investigated function gene, GmDNAJC7, tolerance GmDNAJC7...

A novel electrochemical setup has been developed for soft x-ray absorption studies of the electronic structure of electrode materials during electrochemical cycling. In this communication we illustrate the operation of the cell with a study of the corrosion behavior of copper in aqueous NaHCO3 solution via the electrochemically induced changes of its electronic structure. This development opens...

The Serratia sp. strain ISTD04 has been identified as a carbon dioxide (CO2)-sequestering bacterium isolated from marble mining rocks in the Umra area, Rajasthan, India. This strain grows chemolithotrophically on media that contain sodium bicarbonate (NaHCO3) as the sole carbon source. Here, we report the genome sequence of 5.07 Mb Serratia sp. ISTD04.

The performance of microalgae-based wastewater treatment processes for ammonium-N (NH4+-N) removal depends on the maintenance a favorable pH that is critical minimizing nitrogen escape in form free ammonia (NH3) and preventing high-NH3 or extreme-pH stress. This study developed CO2-inorganic carbon (CO2-IC) buffering system automatically stabilized with supply source efficient photosynthetic re...

Salt stress is a common abiotic that negatively affects crop growth and yield. However, there have been significant differences found on the effect degree management mechanism in plants under neutral salt alkaline stress. In this study, two soybean cultivars, Heihe 49 (HH49, saline-alkali tolerant) Henong 95 (HN95, sensitive), were hydroponically cultured treated with solutions of 25, 50, 75 mM...

Acidic extracellular pH (pHe) is characteristic of the tumor microenvironment. Several reports suggest that increasing pHe improves response immune checkpoint inhibitors in murine models. To increase pHe, either sodium bicarbonate (NaHCO3) or citric acid/potassium-sodium citrate (KNa-cit) was chronically administered to mice. It hypothesized ions (HCO3−), produced from these alkalinizing agents...

Mesembryanthemum crystallinum is a model halophyte that switches from C3 photosynthesis to Crassulacean acid metabolism (CAM) upon extreme abiotic stresses. This study aimed investigate alkalinity-induced root transcriptome profiling in M. crystallinum. seedlings were treated with 50 mM sodium bicarbonate (NaHCO3; pH 7.5) and 90 NaHCO3 (pH 9.5) for 7 d, respectively. Alkalinity-induced differen...

A theoretical and experimental analysis of facilitated transport of CO2 across membranes containing NaHCO3 and the enzyme carbonic anhydrase (carbonate hydro-lyase EC 4.2.1.1) is presented. The necessary diffusion reaction equations are derived and the system constraints defined. For the C O 2 H C O 3 system, mathematical simplifications based on the magnitude of various reaction and concentrat...

Numerous field experiments were conducted at a wide range of sites in Arizona from 1988 through 1999 involving phosphate (P) fertilization of cotton (Gossypium spp.). A total of 21 site-years were used to study the effects of P on both Upland (G. hirsutum L.) and Pima (G. barbadense L.) varieties. The purpose of these experiments was to evaluate University of Arizona (UA) soil fertility guideli...
