Summary: This study demonstrated that melatonin positively regulates the chilling tolerance of cucumber seedlings by activating antioxidant enzymes and inducing key genes related to photosystems and carbon assimilation. The proteome analysis and western blot data revealed that melatonin upregulates protein levels associated with photosystems and carbon assimilation, ultimately alleviating damage to the photosynthetic apparatus and reducing oxidative damage to cucumber seedlings under chilling stress.

Summary: Rice seedlings pretreated with melatonin showed increased salt tolerance and dry weight under salt stress by inhibiting Na+ accumulation, enhancing K+ retention, and improving Na+/K+ homeostasis. Melatonin also enhanced the ability of rice roots to selectively absorb K+ and exclude Na+, as well as increased sensitivity of Na+/K+ transporters to nitric oxide and hydrogen peroxide. This was attributed to an increase in ATP content and H+-pump activity in roots after melatonin pretreatment.

Summary: This study shows that rice plants overexpressing rat neuron nitric oxide synthase (nNOS) have higher endogenous NO levels and exhibit higher tolerance to cadmium stress. The overexpression of nNOS leads to reduced cadmium accumulation in the roots and shoots and upregulation of antioxidant enzyme genes, resulting in decreased accumulation of hydrogen peroxide (H2O2) under cadmium stress. Furthermore, the overexpression of nNOS also induces the upregulation of melatonin biosynthetic genes, resulting in increased melatonin content under cadmium treatment. Overall, this study suggests that nNOS overexpression improves the cadmium tolerance of rice seedlings through reducing cadmium accumulation, enhancing antioxidant capacity, and increasing melatonin biosynthesis.

Summary: Root growth and development is an important indicator of rice's tolerance to root-zone hypoxia. Melatonin has been found to regulate root growth and improve plant stress resistance. In this study, rice seedlings were subjected to hypoxia stress and treated with melatonin to investigate its role in regulating root growth. The results showed that melatonin treatment alleviated the inhibition of root growth caused by hypoxia stress. Morphological and biochemical analyses revealed that melatonin increased root length and density, as well as the activity of antioxidant enzymes. Additionally, melatonin treatment increased the content of indole-3-acetic acid (IAA) in the rice roots. Gene expression analysis suggested that melatonin influenced the expression of genes related to root growth and development. This study highlights the importance of melatonin in modulating root growth under hypoxia stress and provides a new strategy for improving hypoxia tolerance.

Summary: Single-cell C-4 (SCC4) plants, such as Bienertia sinuspersici, have fully functional C-4 photosynthesis in a single cell, making them promising materials for genetic engineering in C-3 crops. The responsiveness of the enzymatic antioxidant system, H2O2 and TBARS contents, and redox regulating proteins in the peripheral compartment (PC) and central compartment (CC) chloroplasts of Bienertia sinuspersici were examined under salinity and drought stress. The results showed that PC chloroplasts (PCC) were less damaged by stress compared to CC chloroplasts (CCC), suggesting that PCC is more tolerant to oxidative damage.

Summary: The study demonstrated that melatonin (MT) can enhance photosynthesis in rice under salt stress conditions by increasing relative water content, sucrose and starch content, and enhancing net photosynthetic rate. This enhancement is mainly attributed to the regulation of maintaining low ROS status, promoting the xanthophyll cycle, and increasing the activities of key photosynthetic enzymes by MT. These findings provide a mechanistic insight into how MT improves the photosynthetic capacity of rice under salt stress.

Summary: This study found that rice glutelin is sensitive to temperature and nitrogen, and their interactions can affect glutelin accumulation during grain filling. Elevated temperature promotes the levels of pro-glutelin and application of nitrogen under warming increases the amount of α-glutelin. However, the increase in glutelin content worsens grain quality, particularly chalkiness and eating 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: 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.
