Summary: Na+ toxicity is a major constraint for plants under saline conditions. Two rice species, Oryza sativa and Oryza coarctata, have different strategies in controlling Na+ uptake. Wild rice increases Na+ loading in xylem for osmotic adjustment, while cultivated rice relies on a specific gene to exclude Na+ from the roots.

Summary: This study investigated the role of gallic acid (GA) in enhancing salinity tolerance in rice seedlings. Salt stress resulted in osmotic, ionic, and oxidative stress in rice seedlings. Supplemental GA partially reversed salt-induced damages by improving osmotic and ionic homeostasis and enhancing the antioxidant defense system and MG detoxification in rice seedlings.

Summary: In this study, a plant growth promoting rhizobacterium (PGPR) ZNP-4 was isolated from the rhizosphere of Ziziphus nummularia and identified as Enterobacter cloacae. The strain showed resistance to salt and metal stress, and significantly improved the growth parameters of wheat plant, maintained membrane integrity, and increased antioxidative enzyme activities. These results suggest that bacteria with similar beneficial traits could be used as bio-fertilizers for crops growing under stress conditions.

Summary: Soil salinity is becoming a critical problem for agriculture under climate change. The study investigated the responses of Solanum melongena, Solanum insanum, and their hybrid to salt stress. Results showed that cultivated eggplant exhibited higher salt tolerance compared to common crops, while S. insanum displayed specific responses, such as increased leaf K+ content. The hybrid showed better growth parameters and had an intermediate behavior between the parent species. These findings suggest the possibility of developing salt tolerance varieties in eggplant by introducing genes from S. insanum.

Summary: The response to salt stress in Tibetan hulless barley involves specific changes in gene expression patterns and modifications of histone proteins, with oxidative stress-related genes upregulated in salt-tolerant varieties and protein complex assembly genes enriched in salt-sensitive varieties. The coordination of H3K4me3 and H3K27me3 may play a crucial role in activating defense mechanisms and improving salt tolerance. Additionally, the selection of salt-related genes and analysis of their homology in different barley varieties reveal the importance of epigenetic regulation in response to environmental stimuli.

Summary: Lemongrass cultivation is threatened by increasing soil salinity, but silicon nanoparticles (SiNPs) can enhance salt tolerance in lemongrass by minimizing oxidative stress and promoting growth and photosynthetic performance. SiNPs also improve enzymatic antioxidant activity and osmolyte accumulation. In addition, SiNPs enhance oil biosynthesis in lemongrass, making them a useful tool to alleviate salinity stress in lemongrass and related crops.

Summary: This study revealed that the responses in roots, rather than in shoots, were crucial for greater salt tolerance in quinoa accessions with low epidermal bladder cell (EBC) density. The tolerant accession showed improved root plasma membrane integrity and ion retention in response to salt, along with faster and root-specific oxidative stress responses within 30 minutes of salt application. This demonstrated that differential root signaling events are essential for halophytic quinoa adaptation to salinity, independent of salt sequestration in EBCs.

Summary: The functional activity of PutHKT1;5 and PutSOS1 in P. tenuiflora roots is finely regulated under saline conditions and by other ion transporters. This coordination of Na+ and K+ transport processes is important for loading them to the xylem or retrieving and extruding Na+ under mild salinity and/or K+ deprivation conditions.

Summary: This review summarizes the current knowledge of how hormones play essential roles in plant responses to boron and how they affect plant growth and development. Hormones are found to mediate the physiological disorders caused by boron deficiencies and excesses. Boron deficiency inhibits root elongation, while boron excess induces the production of reactive oxygen species. Plants adapt to boron deficiency and toxicity through the modulation of hormone production and signaling.

Summary: This study investigated the responses of Chenopodium album to heat, drought, and salinity stresses under field conditions. The results showed that C. album performed best when irrigated with 100 mM salt concentration and had higher drought tolerance. Despite accumulating high levels of Na and Cl ions in their leaves, physiological parameters were not significantly affected. However, when combined and prolonged, the plants exhibited similar levels of stress and no statistical variations were detectable. Shading mitigated the negative impact of salinity and drought stresses. Overall, it is concluded that combined stresses have a noticeable negative impact on C. album, but heat and drought stresses can be alleviated by shade.

Summary: In this study, we investigated the physiological and molecular traits of three wheat cultivars (ZM9023, YM158, and FM1228) under low light intensity using advanced technologies. Through non-standard quantitative technology and quantitative proteomics technology, we found that YM158 had lower dry matter accumulation compared to ZM9023 and FM1228. We also observed differences in photosynthetic parameters and light use efficiency between the cultivars. Furthermore, proteomic analysis revealed specific protein expression patterns related to light capture and photosystem activity. These findings suggest that considering Fv/Fm, ETR, and phi PS(II) in shade tolerance screening could aid in wheat breeding.

Summary: Osmotic stress from salinity and drought negatively affects crop production, and there is a need to develop stress-tolerant crops with higher water use efficiency. Improving water use efficiency can be achieved by reducing stomatal transpiration without compromising CO2 uptake under osmotic stress conditions. Manipulating stomatal density holds promise as a strategy to enhance water use efficiency.

Summary: Phosphorus (P), an essential nutrient for plants, plays a crucial role in plant growth and development. However, the limited availability of phosphorus in soil presents challenges for crop productivity, especially when plants face abiotic stresses. This review aims to analyze the impact of phosphorus supply on various aspects of plant growth and development, with a focus on stomatal development and operation. The review also discusses recently discovered genes associated with phosphorus-dependent stress regulation and evaluates the feasibility of implementing phosphorus-based agricultural practices to mitigate the adverse effects of abiotic stress.

Summary: This study investigated the mechanisms by which melatonin (MT) improves drought tolerance in pepper plants. The plants were treated with a foliar spray of 0.1 mM MT and grown under 80% and 40% field capacity for 3 days. Drought stress significantly decreased plant dry weight, water content, PSII efficiency, chlorophyll, protein, and nitrogen content, while increasing oxidative stress markers and enzyme activities. MT pre-treatment alleviated oxidative stress and improved nitrogen metabolism by activating various enzymes. It also reduced nitrogen content and enhanced plant growth and photosynthesis.
