Article Abstract
The phytohormone abscisic acid (ABA) triggers the activation of Snf1-related protein kinase 2s (SnRK2s) for adaptation to abiotic stress conditions. However, osmotic stress-induced ABA accumulation is slow while Ca signals occur immediately. In this issue of Developmental Cell, Li et al. show that a subset of calcium-dependent kinases decode Ca signals to directly control SnRK2 activation and thus early osmotic stress regulation in plants.

Exercise associated hyponatremia (EAH) is a medical condition that can occur during physical exertion. Initially, EAH was considered to be restricted to extreme endurance activities, such as ultramarathons and Ironman triathlons. However, it has been more recently recognized in a variety of sports, including team sports and in shorter-duration events.

Hyperosmolality-triggered physiological drought hinders plant growth and development, leading to a drop in crop yields. Hyperosmolality triggers calcium signaling, and yet how osmotic-induced calcium signaling participates in cellular osmotic response remains enigmatic. To date, several Ca channels and transporters have been identified to regulate osmotic-induced calcium signal generation (CaSG) or Ca homeostasis.

Litopenaeus vannamei exhibits strong salinity adaptation; however, its survival and growth are significantly reduced in freshwater environments. To investigate the response mechanisms of L. vannamei to freshwater conditions, gill tissues from shrimp cultured for 30 days in both freshwater and seawater environments were used as experimental material in this study.

To cope with heat and water stress, evergreen and deciduous species from hot and arid deserts should adjust their stomatal conductance ( ) and leaf water potential (Ψ) regulation in response to changes in soil water availability, high temperatures, and vapour pressure deficits (VPDs). To test whether phenology induces changes in -Ψ coordination, we tested for associations between 14 leaf traits involved in leaf economics, hydraulics, and stomatal regulation, including minimum seasonal water potential (Ψ) and maximum ( ), turgor loss point (Ψ), osmotic potential (Ψ), leaf area (LA), and specific leaf area (SLA), across 12 tree species from the Sonoran Desert with contrasting phenology. We found that foliar phenology, leaf hydraulics, and leaf economic traits are coordinated across species and organized along the axis of physiological efficiency and safety in response to temperature and VPD.

Introduction: Wheat is one of the three major cereal crops in the world and is susceptible to the effects of drought stress. Rhizosphere microorganisms can affect plant growth by altering nutrient absorption and resistance to stress. Studying the plant-microbe interaction under drought stress to reveal the impact of soil microorganisms on plant growth in dry land has important scientific significance.
