Summary: In this study, the ZmERD15 genes in maize were comprehensively analyzed. The results showed that these genes play important roles in regulating stress responses and their expressions are regulated by PEG, salinity, and ABA. In addition, heterologous expression of ZmERD15 genes in yeast significantly enhanced salt tolerance. The findings provide insights into the biological function and molecular mechanism of ZmERD15 genes in regulating stress responses in maize.

Summary: Food security relies on plant productivity and resilience to climate change, which can be enhanced by silicon's regulation of various mechanisms in plants. Silicon aids in improving plant growth productivity, alleviating biotic and abiotic stress conditions, and plays a role in osmotic adjustment, metabolic processes, and phytohormones. Further research on silicon transporters and regulatory genes is needed for better understanding and application in different stress conditions.

Summary: Rice, as one of the most significant staple foods worldwide, has faced challenges due to climate change and abiotic stress. Abiotic stressors such as drought, heat, cold, salt, submergence, and heavy metal toxicity have resulted in reduced photosynthetic efficiency, imbalanced redox homeostasis, and tissue damage in rice plants. Rice plants respond to these stressors through various morphological, biochemical, and physiological mechanisms.

Summary: Water deficit inhibits plant growth and leads to overproduction of reactive oxygen species (ROS), causing oxidative stress. Iodine (I) has been shown to enhance the antioxidant defense system and improve photosynthesis under adverse conditions. In this study, soybean plants exposed to potassium iodide (KI) concentrations of 10 and 20 .mol L-1 showed increased biomass, improved gas exchange, and reduced lipid peroxidation under water deficit. However, higher KI concentrations negatively affected photosynthetic efficiency, biomass accumulation, and partition under well-irrigated conditions.

Summary: Globally, the increasing effects of metal and metalloid toxicity are mainly attributed to anthropogenic causes, particularly soil contamination. Plants have evolved mechanisms such as hyperaccumulation, tolerance, exclusion, and chelation with organic molecules to overcome metal/metalloid stress, while omics research has enhanced understanding of plant genome and transcriptome plasticity in response to these stimuli.

Summary: Microbial volatile compounds (MVCs) are widely distributed in nature and have significant applications in various fields. They are small odorous compounds released by bacteria and fungi, which have the ability to diffuse more readily and travel farther distances compared to other non-volatile microbial metabolites. In natural environments, plants interact with various microorganisms and respond differently to MVCs, which can modulate plant growth, improve photosynthesis, and enhance plant resistance to abiotic stressors.

Summary: Strigolactones, as phytohormones, play important roles in plant development and response to environmental stress. This article examines the evidence of their involvement in stress acclimation strategies, focusing on osmotic stress. The findings suggest that strigolactones function as backstage operators, adjusting the acclimation responses based on the plant's stress experience and contributing to the formation of environmental memory.

Summary: This review highlights the bioenergetic role of polyamines in plant protection and development and proposes a universal model for describing polyamine-mediated stress responses. Polyamines can regulate the energy and structure of the photosynthetic apparatus and control the photochemical and non-photochemical quenching of energy. By altering the composition of polyamines, stress-sensitive plants can be made tolerant.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.

Summary: This study characterized the expression profiles of mRNAs and ncRNAs in switchgrass under drought stress. The up-regulated mRNAs were enriched in starch and sucrose metabolism pathway, while the differentially expressed lncRNAs potentially regulated protein-coding genes. The study also constructed regulatory networks and validated the functionality of the target gene PvSS4 in enhancing drought tolerance.

Summary: This study aimed to investigate the physiological response of broccoli leaves to abiotic stresses such as salinity and boron toxicity/deficiency. The results showed that the combined stress of salinity and boron deficiency resulted in a significant reduction in plant biomass, and the adaptation mechanisms were associated with water and boron concentration in the leaves. The expression patterns of PIP aquaporins varied among the different stress treatments, and their presence in the plasma membrane and interaction with the lipid environment played potential regulatory roles in facilitating salinity-boron stress adaptation mechanisms.

Summary: Plants activate a sophisticated signaling cascade in response to pests and pathogens, with lipids playing a crucial role in mediating these defense responses. Different types of lipids are involved in cell signaling during plant-pathogen interaction and each lipid has specific relevance and contributes to specific signaling cascades. Lipid biosynthetic enzymes, including phospholipases, are involved in the production of defense signaling molecules. Lipids participate in stress signaling by mediating signal transduction, acting as precursors for bioactive molecules, regulating ROS formation, and interacting with phytohormones.
