Summary: Salinity stress negatively affects agricultural productivity, but the application of zinc has been found to mitigate its adverse effects. Zinc improves various growth and stress response processes in plants, including seed germination, water uptake, nutrient absorption, and antioxidant activity. Additionally, zinc application increases the synthesis of secondary metabolites and the expression of stress responsive genes. This review article fills knowledge gaps regarding the role of zinc in mitigating salinity stress.

Summary: Extreme environmental factors significantly affect the bioactive components and essential oil content in medicinal and aromatic plants. The production of essential oils in plants is influenced by various factors, which in turn affect the oil yield and constituents. Essential oils are accumulated in specialized secretory tissues and are responsible for producing aroma. Understanding the impact of stress on essential oil quantity and quality can have a positive impact on growers and processors. This review article discusses essential oil biosynthesis, the influence of environmental factors, and strategies to enhance essential oil production under unfavorable conditions.

Summary: Low temperatures are common environmental conditions that negatively affect plant growth and crop productivity. Plants have evolved mechanisms involving polyamines (PAs) and gamma-aminobutyric acid (GABA) to adapt and resist low temperatures. GABA plays a central role in the defense system during low-temperature tolerance and helps mitigate reactive oxygen species (ROS) damage in plants. However, our understanding of the specific functions of these metabolites in conferring cold tolerance is still limited.

Summary: Soil salinity is a major stressor for plant growth, and the application of plant growth regulators (PGRs) is a potential solution to mitigate salinity-induced yield losses. However, the effectiveness of PGRs is influenced by factors such as genotype, timing of application, and salinity levels, making their practical application limited. Breeding crops for salinity tolerance remains a more reliable approach to minimize the impact of salinity on plant growth and yield, with further research needed to understand the mechanisms of interaction between PGRs and membrane transporters mediating plant ion homeostasis.

Summary: Marine organisms play a crucial role in the carbon cycle by producing and consuming organic matter. Osmolytes are small metabolites that regulate osmolarity and can be released as abundant dissolved substrates. The genetic potential of marine microbes suggests active recycling of osmolytes, which can serve as a significant source of nutrients for diverse microbial groups in the marine ecosystem.

Summary: The sensitivity of rice plants to salinity is a major challenge for rice growth and productivity in salt-affected lands. Priming rice seeds with humic acid has been shown to improve salt tolerance in rice, but the mechanisms of action are not fully understood. This study investigated the impact of humic acid priming on the growth and physiological processes of rice plants under different salinity levels. The results suggest that humic acid application can enhance salt tolerance in rice by maintaining ionic homeostasis, osmolyte content, and efficient antioxidant defense system.

Summary: This study aimed to investigate the effects of indole acetic acid (IAA) and Citrate Capped Silver Nanoparticles (Cit-AgNPs) on various attributes of maize under salinity stress. The nanoparticles were analyzed using scanning electron microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDX), Thermo-gravimetric analysis (TGA), and Differential thermal analysis (DTA). The results showed that the foliar application of IAA and Cit-AgNPs significantly improved the agronomic attributes, photosynthetic pigments, osmolytes, and antioxidant enzymes in maize plants under high salinity stress.

Summary: The study evaluates the impact of salt stress on germination and emergence of pitaya seeds. It finds that seeds matured in the environment with red fruit flesh are more tolerant to salt stress. Salt concentrations above 2500 ppm significantly reduce growth, while concentrations above 5000 ppm significantly reduce germination. Germination percentage is the most important trait determining seed quality.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
