Summary: The study showed that under cold stress conditions, tolerant chickpea genotype exhibited lower H2O2 content and electrolyte leakage compared to the sensitive genotype. The tolerant genotype also demonstrated higher activity of antioxidant enzymes and accumulation of polyamines, contributing to its cold tolerance.

Summary: This study evaluated the physiological performance of different chickpea genotypes under cold and heat stress. The results showed that cold stress reduced photosynthetic efficiency and chlorophyll content, while increasing starch accumulation. Under heat stress, chickpeas maintained photosynthetic efficiency but had reduced chlorophyll content. Genetic variation in response to cold and heat stress was found among the tested genotypes.

Summary: Bamboo forests cover a significant area of Chinese forestland. Titanium dioxide nanoparticles (TiO2 NPs) have been used for plant protection against heavy metal stress. The study found that TiO2 NPs reduced oxidative stress in plants by increasing antioxidant capacity, decreasing lipoperoxidation, and reducing accumulation of Cu and Pb. Additionally, TiO2 NPs were more effective for Cu than Pb, and high concentrations of TiO2 NPs enhanced plant growth and development under heavy metal stress.

Summary: This study demonstrates the effectiveness of cold plasma in eliminating Staphylococcus aureus. Short-term exposure to cold plasma resulted in upregulation of stress proteins, antioxidants, nitrosative stress, and transporter proteins in the bacteria, while prolonged treatment affected DNA repair mechanism, transcription, and translation processes. The majority of genes related to cell membrane synthesis were downregulated, indicating compromised cell integrity.

Summary: The objective of this study was to investigate the ameliorating effect of exogenous melatonin (MT) on cadmium (Cd)-mediated injury in chickpea seedlings and determine the optimal application approach. The results showed that exogenous MT significantly mitigated the deleterious effect of Cd on seedling growth by improving antioxidant activities and gene expression. Adding MT simultaneously with Cd had a more pronounced beneficial effect compared to late supplementation with MT. Overall, exogenous MT enhanced chickpea tolerance to Cd contamination through its antioxidative and gene regulatory effects.

Summary: Turbot early immune responses to infection with A. salmonicida subsp. salmonicida were evaluated in this study. The results showed no significant differences in blood and humoral parameters, as well as oxidative stress indicators. However, changes in the expression of genes related to inflammation and immunity were observed.

Summary: This study examined the effects of silver nanoparticles (AgNPs) with different coatings (PVP and CTAB) on oxidative stress and proteome changes in tobacco seedlings. The results showed that both types of AgNPs induced reactive oxygen species formation and increased the expression of antioxidant defense proteins, confirming oxidative stress as an important mechanism of AgNP phytotoxicity. The responses of seedlings differed depending on the type of AgNP, with CTAB-coated AgNPs causing more severe damage to lipids, proteins, and DNA molecules, as well as more noticeable changes in protein expression.

Summary: The study investigated the biomarker responses of freshwater bivalve mussel Unio ravoisieri after exposure to gold and titanium dioxide metallic nanoparticles. The results showed induction of oxidative stress, overproduction of H2O2, and changes in enzyme activities in the gills and digestive glands. The digestive gland was identified as the main target organ of Au/TiO2NPs contamination.

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.
