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: Transcriptomics studies show that nanomaterials have potential toxicity in plants, affecting stress-responsive genes, but overall impact on the transcriptome is minimal. Environmental challenges like pathogens, salinity, or drought induce stronger transcriptional responses compared to nanoparticles. Plants lack specific gene regulation for novel nanomaterials, using common regulatory circuits with other stress responses such as inhibition of genes for root development and pathogen response. Other reviewed works also support these findings.

Summary: Agricultural soil degradation is increasing at an alarming rate, influenced by climate change and intensified agricultural practices. Understanding the impacts of climate change and soil degradation on plant physiology is crucial for the development of effective strategies to mitigate crop productivity losses. Proline, an amino acid, has been recognized for its roles in plant cells under osmotic stress, showing a positive correlation between proline accumulation and tolerance to abiotic stress. However, recent studies question the assumption that proline accumulation always indicates improved stress resilience, suggesting the need for further biochemical and physiological endpoints.

Summary: Plant-derived smoke contains karrikins (KARs), which are a type of plant growth regulators that affect seed germination, seedling vigor, and other photo-morphogenetic responses. KARs improve plant performance under various environmental constraints by modulating antioxidative metabolism and up-regulating stress-related genes expression. This modulation involves an interplay with transcription factors and endogenous plant growth regulators.

Summary: Melatonin, derived from tryptophan, is a conserved domain found in various organisms. It plays a crucial role in plant development and stress responses. Melatonin acts as a multi-regulatory substance by regulating the transcription of many genes. Although research on melatonin in plants is still in its early stages, it is important to further study its potential in biochemical and physiological processes, stress response, detoxification mechanisms, and other beneficial effects. Melatonin acts as an antioxidant by scavenging reactive nitrogen species (RNS) and reactive oxygen species (ROS), and it also activates enzymes involved in ROS detoxification. This comprehensive review focuses on the protective mechanisms of melatonin against abiotic stress in plants and highlights its potential in crop research.

Summary: The purpose of this research was to investigate the negative effects of salt stress on soybean plants in terms of anatomical, morphological, nutritional, physiological, and biochemical parameters. The study found that concentrations of 50 to 200 mM Na+ significantly reduced the levels of K, Ca, and Mg in the plants, and had negative effects on photosynthesis, gas exchange, and photosynthetic pigments, which were likely caused by oxidative stress. Interestingly, at concentrations below 100 mM Na+, there were changes in epicuticular wax deposition, stomatal quantity and morphology, and leaf epidermis thickness in soybean plants. Overall, significant deleterious effects were observed in soybean plants under salt stress conditions above 100 mM Na+.

Summary: The present study aimed to improve drought stress tolerance in eggplant by applying alpha-tocopherol (TOC) externally. Two methods, foliar spray (FS) and pre-sowing seed treatment (PS), were used for this purpose. Water deficiency treatment was applied to 32-day-old seedlings of two eggplant cultivars, Janak and Black Beauty. Different concentrations of TOC were applied as PS and FS. The results showed that drought stress significantly reduced plant growth and chlorophyll contents, but increased proline, glycine betaine, malondialdehyde (MDA), hydrogen peroxide, relative membrane permeability, peroxidase, and superoxide dismutase activities in both cultivars. The application of TOC had a positive effect on overcoming the adverse effects of water stress on eggplants, improving plant growth and various physiological parameters. Overall, FS treatment was more effective in improving proline, glycine betaine, ascorbic acid, and enzyme activities, while PS treatment was more effective in reducing membrane permeability and improving total soluble proteins. The study concluded that TOC application was useful in mitigating the harmful effects of drought stress on eggplants of both cultivars.

Summary: This study aimed to assess the toxicity of Chlorpyrifos (CP) on Brassica juncea L. and investigate the ameliorative potential of phytohormone, 24-epi-brassinolide (EBL) mediated plant-microbe interaction in B. juncea L. The results showed that EBL and B2 treatment significantly increased the content of chlorophyll, carotenoids, flavonoids, anthocyanins, and xanthophylls in CP-stressed B. juncea seedlings. The supplementation of EBL and PGPR improved the expression of genes related to photosynthetic pigments and metabolic pathways. These findings suggest that EBL and PGPR can reduce CP-induced toxicity and promote recovery in B. juncea seedlings.

Summary: Microplastic accumulation in the soil-plant system can stress plants and affect product quality. The effect of microplastics on plants is inconsistent and the molecular mechanisms are unknown. This study investigated the molecular mechanism underlying the growth of soybean plants in soil contaminated with microplastics and arbuscular mycorrhizal fungi. The results showed that microplastic stress led to a decline in plant growth, chlorophyll content, and soybean yield. Microplastic addition caused oxidative stress and inhibited rubisco and root activity. However, arbuscular mycorrhizal fungi inoculation alleviated the phytotoxic effects of microplastics, induced the plant defense system, and upregulated genes responsible for metal uptake in soybean.
