Wintertime measurements near Barrow, Alaska, showed that bacteria near the surface of first-year sea ice and in overlying saline snow experience more extreme temperatures and salinities, and wider fluctuations in both parameters, than bacteria deeper in the ice. To examine impacts of such conditions on bacterial survival, two Arctic isolates with different environmental tolerances were subjecte...

germination stage is an important stage of plant growth stage that often is affected by environmental stress including water and salinity stresses including drought and salinity. in order to study germination characteristics of scrophularia striatain water and salinity stress conditions at different temperatures an experiment was conducted. temperatures regimes included 5, 10, 15, 20, 25, 30 an...

In the current scenario of human-driven climate change, extreme weather events will likely affect agricultural production worldwide. Soilless systems have recently arisen as a solution to optimize use natural resources, such water and soil, hence contribute reducing environmental impact agriculture. However, nutritional imbalance due adverse factors, drought, high temperatures, salinity, might ...

In order to demonstrate filtration rate of edible cockle Cerastoderma edule under different salinity and temperature conditions, two groups namely healthy and parasited with Labratrema minimus (Bucephallidae; Digenea) were compared. Results showed that the parasited ones had difficulties in adaptation to the extreme conditions of salinity and temperature. Our results also showed that a healthy ...

quinoa (chenepodium quinoa willd) is a grain-like crop which has a high production potential in iran. due to its seeds high nutritional value, it is compared with milk by the fao. in order to study the effects of temperatures on seed germination of quinoa seeds under salinity stress conditions, an experiment was conducted in seed lab of the university of tehran in karaj. temperatures regimes in...

In addition to drought and extreme temperatures, soil salinity represents a growing threat to crop productivity. Among the cereal crops, barley is considered as notably salt tolerant, and cultivars show considerable variation for tolerance towards salinity stress. In order to unravel the molecular mechanisms underlying salt stress tolerance and to utilize the natural genetic variation of barley...

CBL-interacting protein kinases (CIPKs) mediate many plant responses to abiotic stress. However, their functions are poorly understood in halophytes. In this study, we isolated a CIPK gene, NtCIPK2, from the halophyte Nitraria tangutorum. By sequence alignment and the construction of a phylogenetic tree, we found that NtCIPK2 is similar to CIPK2 proteins from other plants, and contains conserve...

Halophytes are remarkable plants that can tolerate extremely high-salinity conditions, and have different salinity tolerance mechanisms from those of glycophytic plants. In this work, we investigated the mechanisms of salinity tolerance of an extreme halophyte, Kochia sieversiana (Pall.) C. A. M, using RNA sequencing and physiological tests. The results showed that moderate salinity stimulated ...
