Summary: The study demonstrates that melatonin treatment can enhance the photosynthetic efficiency and reduce photoinhibition of tomato plants under low night temperatures. This is achieved by regulating electron transport and upregulating genes and proteins related to environmental adaptation and chloroplast integrity maintenance. These findings provide insights into the molecular mechanism of melatonin-mediated abiotic stress resistance.

Summary: Melatonin, a naturally occurring compound, plays a crucial role in plant growth and development, as well as in the regulation of physiological functions in response to abiotic stresses. This compound acts as an antioxidant, protecting plants from oxidative damage caused by reactive oxygen species. By enhancing the plant antioxidant defense system, melatonin improves plant growth and development under various abiotic stresses such as drought, salinity, high temperature, flooding, and heavy metals. The understanding of melatonin's role in plant biology is important for developing strategies to enhance the resilience of crops in the face of climate change.

Summary: Inhospitable conditions, such as drought, extreme temperatures, salinity, heavy metals, and irradiation, lead to a reduction in agricultural productivity worldwide. Reactive oxygen species (ROS) generated by these stresses cause oxidative damage in plants. Melatonin serves as a growth regulator and protector against abiotic stresses due to its natural antioxidant properties. It also regulates genes associated with photosynthesis, making it an attractive chemical agent to improve plant resilience and optimize photosynthetic efficiency.

Summary: High soil pH negatively affects blueberry growth and physiological functions. This study comprehensively evaluated the high soil pH tolerance of 15 blueberry cultivars through pot experiments and calculated the high-pH soil tolerance coefficient (HSTC) based on 16 phenotypic and physiological indices. The results revealed inhibited growth, altered antioxidant system activities, and changes in chlorophyll content, photosynthetic rate, and stomatal conductance in response to high soil pH stress. The cultivars were classified into different tolerance categories. Certain traits were identified for predicting and evaluating the high soil pH tolerance of blueberry cultivars.

Summary: In this study, the regulation of the human melatonin biosynthesis-related enzyme HIOMT in alkaline stress in apple plants was investigated. The overexpression of HIOMT under alkaline stress increased the concentration of endogenous melatonin in apple leaves, alleviating plant growth inhibition, enhancing root development, leaf photosynthesis, and antioxidant capacity, and stabilizing cell membrane permeability and ionic balance. Additionally, the transgenic lines also increased the concentrations of organic acids, such as oxalic acid, malic acid, malonic acid, citric acid, and succinic acid, which alleviated high pH stress. These results highlight the critical role of HIOMT overexpression in the alkaline stress tolerance of apple plants.

Summary: The increasing health awareness among consumers has led to a shift towards vegan and non-dairy prebiotics as substitutes. Non-dairy prebiotics fortified with vegan products have become popular in the food industry, especially in water-soluble plant-based extracts, cereals, and fruits. The use of inulin, oligofructose, polydextrose, fructooligosaccharides, and xylooligosaccharides as prebiotic components in these products has various physiological effects that can prevent and treat chronic metabolic diseases. This review focuses on understanding the mechanisms of non-dairy prebiotics on human health, the relationship between nutrigenomics and prebiotic development, and the role of gene-microbe interactions. It provides important information for industries and researchers on prebiotics, non-dairy prebiotics, and prebiotic-based vegan products.

Summary: The potato apical leaf curl disease caused by ToLCNDV-potato significantly affects the morphological parameters and photosynthetic pigment system in potato cultivars, with a lower impact observed in the tolerant cultivar. The viral infection also leads to increased leakage of oxidative metabolites and imbalance of starch metabolism, resulting in altered carbohydrate profiles. Furthermore, antioxidant enzyme activity is enhanced, particularly in the resistant cultivar. These findings contribute to our understanding of regulatory mechanisms and provide insight for breeding potato varieties with tolerance to ToLCNDV-potato.

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.

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: 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.
