Summary: The study shows that calcium ion can effectively reduce Na+ uptake, increase the activity of root PM H(+)ATPase, and improve the tissue K+/Na+ ratio, thus enhancing the salt tolerance of rice. The mechanisms involved may include Ca2+ signaling-mediated phosphorylation of PM H(+)ATPase and increased transcription of 14-3-3 protein in response to NaCl-induced stress, particularly in salt-tolerant rice varieties.

Summary: Plants minimize Na+ toxicity under salt stress by utilizing membrane transporters and regulatory kinases to regulate Na+ levels. The expression of regulatory kinases enables transporters to effectively manage cytosolic Na+ levels, crucial for plant tolerance to salinity. Bioinformatics-based identification of kinases like OsCIPK24 in salt-sensitive crop plants may lead to biotechnological interventions to enhance salt tolerance and increase annual yield.

Summary: Excessive Na+ in soils inhibits plant growth. This study found that Na+ stress triggers primary calcium signals in a specific cell group within the root differentiation zone of Arabidopsis, forming a sodium-sensing niche. The amplitude and speed of these calcium signals increase with rising Na+ concentrations, providing quantitative information about the stress intensity. The researchers also identified a Ca2+-sensing mechanism that measures the stress intensity and activates appropriate salt detoxification responses.

Summary: Glutamate induces Ca2+ signaling in the suprachiasmatic nucleus (SCN) by activating intracellular mechanisms involving Na+ loads, Na+/K+-ATPase (NKA), and Na+/Ca2+-exchanger (NCX). The presence of Na+ loads leads to slower Ca2+ clearance and increased rebound Ca2+ suppression. However, even in the absence of external Na+, additional Ca2+ handlers are involved in the slower Ca2+ clearance induced by glutamate.

Summary: Root hairs are tubular outgrowths of epidermal cells that enhance root efficiency in water and nutrient absorption. Their growth is associated with pH oscillations and changes in reactive oxygen species (ROS) and cytoplasmic Ca2+ concentrations. While the role of pH as a growth signal in root hairs is not fully understood, it has been shown to play an important role in pollen tube growth.

Summary: Salinity affects the growth and photosynthesis of Avicennia marina, a mangrove plant. At 200 mM NaCl, the whole-plant dry weight and photosynthetic parameters increased, but decreased over 400 mM NaCl. High salinity caused reduction in starch grain size, swelling of thylakoids, separation of granal stacks, and even destruction of the envelope. The salt glands in the adaxial epidermis of the leaves excrete Na+ effectively below 400 mM NaCl, improving its salt tolerance.

Summary: Through various biophysical techniques, this study reveals the complex interaction mechanism between CaM and NHE1, identifying multiple states and structures of the NHE1:CaM complex that can be modulated by stoichiometries, calcium concentrations, and phosphorylation. Experimental results suggest that CaM may enhance NHE1 regulation and indicate that this structural diversity is relevant to other CaM complexes as well.

Summary: In rice, the PM-localized PP2C.D phosphatase SAL1 inhibits PM H+-ATPase to regulate NRAT1 transporter-mediated Al uptake and Al resistance. Aluminum toxicity remains a primary constraint for crop production in acidic soils. The molecular mechanisms underlying high Al resistance in rice and the strategies used by rice and Arabidopsis to defend against Al toxicity are revealed.

Summary: Turmeric, an important crop in Indian cuisine, produces natural yellow color and curcuminoids which are widely used in medicinal practices. Water deficit and reduced temperature negatively affect turmeric growth, physiological adaptation, and rhizome yield, with decreased curcuminoid content and upregulated expression of curcuminoid-related genes under controlled water-deficit conditions.

Summary: This study evaluated the uptake, translocation, physiological adaptation, metal toxicity, and growth inhibition of rice genotypes grown in acid soil contaminated with iron and aluminum. Different genotypes showed varying levels of tolerance and adaptation to the metal contamination, with some exhibiting enhanced metal accumulation and others maintaining low levels of toxicity through specific gene expressions and biochemical mechanisms. The findings provide insights into potential screening and breeding efforts to increase rice production in Fe/Al-contaminated acid soils.

Summary: In this study, the effects of paclobutrazol (PBZ) and NaCl salt elicitors on water spinach were investigated. The results showed that PBZ treatment reduced the height and shoot length of the plants, while NaCl treatment inhibited shoot length in one cultivar but not in another. PBZ-pretreated plants exposed to NaCl showed reduced Na+ and Ca2+ levels, leading to sustained photosynthetic abilities and plant biomass. Interestingly, NaCl-treated cultivars showed increased levels of soluble sugar, ascorbic acid, and tocopherol.

Summary: Egeria densa, a submerged aquatic plant, is commonly used as a bioindicator for freshwater quality. This study investigated the response of E. densa to salt stress and found that it expresses salt-tolerant genes, accumulates solutes, and undergoes physiological changes. The results suggest that E. densa can tolerate low salt concentrations, but further validation is needed in natural estuarine environments.

Summary: Geographic zone and seasonal variations are major factors affecting the quality and quantity of cultivated medicinal plants, with suitable harvesting time being crucial in Indian pennywort cultivation. Low temperatures during winter can significantly impact the growth and metabolic enrichment of Indian pennywort. This study aimed to determine the optimum temperature for cultivation to achieve superior growth characteristics, physiological adaptations, and secondary metabolite enrichment. Experiments revealed that an ambient air temperature of 25 degrees C resulted in maximum leaf area and overall biomass, while lower temperatures (15 degrees C) inhibited various growth parameters and photosynthetic rates. Furthermore, exposure to 15 degrees C led to changes in pigment parameters, glucose and soluble sugar levels, as well as an increase in certain secondary metabolite concentrations. However, other secondary metabolites showed a significant decrease. Overall, an air temperature of 25 degrees C was found to be optimal for Indian pennywort cultivation to maximize biomass and secondary metabolite production.

Summary: Increasing salinity in agricultural land hampers crop yields, especially for salt-sensitive plants such as rice. A study finds that using an antitranspirant (AT) can enhance salt tolerance in rice by obstructing sodium (Na) transpiration flow. This research evaluates the effects of an AT on Na enrichment and yield in salt-stressed rice plants.

Summary: The objective of this study was to assess the impacts of exogenously-applied foliar MeJA on morphological, physiological, and biochemical traits as well as total andrographolide contents of A. paniculata under water-deficit stress. The results showed that foliar application of 250μM MeJA improved the negative effects of water-deficit stress by enhancing leaf osmotic potential, chlorophyll degradation, photon yield of photosystem II, net photosynthetic rate, and transpiration rate. Especially under water-deficit conditions, 125μM MeJA treatment increased the total andrographolide content and economic benefits.
