Here, we present the draft genome of Haladaptatus sp. strain R4, a halophilic archaea that produces an orange-pink pigment and is capable of growing in a wide salinity range. The genome assembly shows genes for arsenic resistance, siderophore production, trehalose and glycine betaine biosynthesis, uptake and transporters of sodium, potassium, and chloride ions.

Using cereal crops as examples, we review the breeding for tolerance to the abiotic stresses of low nitrogen, drought, salinity and aluminium toxicity. All are already important abiotic stress factors that cause large and widespread yield reductions. Drought will increase in importance with climate change, the area of irrigated land that is salinized continues to increase, and the cost of inorg...

The observations of a long-term experiment on the use of saline water were used to compare the crop tolerance to salinity. Salinity affected significantly yield, evapotranspiration, pre-dawn leaf water potential and stomatal conductance. The higher the salinity, the lower the yield, evapotranspiration, pre-dawn leaf water potential and stomatal resistance. The crop classification, based on soil...

For the large pores and cracks of reservoirs with low temperatures, high salinity, and low permeability, a new type of high strength gel ABP system is developed in this paper. The defects of conventional gels such as weak gel strength, no gelling, and easy dehydration are overcome under the conditions of low temperature and high salinity. The temperature and salt resistance, plugging characteri...

Capacitance and resistivity sensors can be used to continuously monitor soil volumetric water content (θ) and pore-water electrical conductivity (EC(p)) with non-destructive methods. However, dielectric readings of capacitance sensors operating at low frequencies are normally biased by high soil electrical conductivity. A procedure to calibrate capacitance-resistance probes in saline conditions...

Plants, as sessile organisms, survive environmental changes by prioritizing their responses to the most life-threatening stress by allocating limited resources. Previous studies showed that pathogen resistance was suppressed under abiotic stresses. Here, we show the mechanism underlying this phenomenon. Phosphorylation of WRKY45, the central transcription factor in salicylic-acid (SA)-signallin...

Several factors influencing the hatching of Schistosorna japonicum eggs were reported by Miyagawa (1916), Faust and Meleney (1924), Magath and Mathieson (1946), Faust (1947), Maldonado and Matienzo (1948), Ingalls et al (1949) and Sugiura et al (1954), but there were only a few investigators who have dealt with the resistance of the eggs to various external environmental conditions. These probl...

Biofilm-forming marine bacterium Pseudomonas aeruginosa JP-11 was isolated from coastal marine sediment of Paradeep Port, Odisha, East Coast, India, which resisted up to 1,000 ppm of cadmium (Cd) as cadmium chloride in aerobic conditions with a minimal inhibitory concentration of 1,250 ppm. Biomass and extracellular polymeric substances (EPS) secreted by the cells effectively removed 58.760 ± 1...

sericulture has played a very important role in the socio-economic empowerment of rural and semi-urban population. the eco-friendly nature of the industry, in addition to its employment generation potential, low investments and frequent returns, has rendered the industry as one of the most suitable land based economic activity, particularly in the context of global movement against environmenta...
