Summary: Phyto-hormones in plants are crucial for regulating crop growth and yield, especially under salt stress. Recent studies have highlighted the significant role of exogenous hormones, such as gibberellin (GA) and salicylic acid (SA), in regulating cotton's response to salt stress. However, a comprehensive understanding of the mechanisms by which these hormones regulate growth and yield under salt stress is still lacking.

Summary: Sensing and responding to changes in ambient temperature is crucial for the survival of all living organisms. A study on the response of rice seedlings to elevated temperatures revealed uniquely regulated genes and pathways in the heat-tolerant rice cultivar, particularly associated with auxin and ABA as part of the heat stress response. Analysis of regulatory network between transcription factors and their target genes under various temperature conditions provided insights into temperature-responsive genes and potential candidates for thermotolerance in rice.

Summary: Hydrogen sulfide (H2S) plays an important role in signal transduction and adaptive regulation in plants. It improves plant responses to stress conditions by interfering with the cellular redox regulatory network and post-translational modifications of proteins. Additionally, H2S interacts with other gas signals and plant growth regulators to activate multiple signaling pathways.

Summary: To adapt to changing environments, plants have evolved regulatory mechanisms that balance their growth and stress responses. This study reveals the involvement of tryptophan synthase beta subunit 1 (TSB1) in coordinating the growth hormone auxin and the stress hormone abscisic acid (ABA), thereby affecting plant growth and abiotic stress responses. TSB1 serves as a key coordinator by balancing Trp and ABA homeostasis.

Summary: In this study, a novel iTRAQ-based proteomic strategy was used to investigate protein synthesis and regulation responses to waterlogging in tolerant and sensitive genotypes. Several differentially expressed proteins were identified, suggesting that waterlogging stress may redirect protein synthesis and reduce chlorophyll synthesis and enzyme abundance involved in photorespiration, thereby influencing synthesis of other metabolic enzymes. These differentially expressed proteins could be used as biological markers for enhancing waterlogging tolerance in future crop breeding programs.

Summary: The plant hormone auxin plays a crucial role in regulating plant growth and development. Reactive oxygen species (ROS) also serve as signaling molecules at low concentrations, but excessive accumulation of ROS due to environmental stresses can be detrimental to cells. Nitric oxide (NO), a gaseous signaling molecule, has various beneficial effects on plants. Together, auxin, ROS, and NO are involved in developmental processes and abiotic stress tolerance in plants.

Summary: Hydrogen peroxide (H2O2) plays a crucial role in modulating root development and architecture under both normal and adverse environmental conditions. Nitric oxide (NO) and hydrogen sulphide (H2S) also have diverse functions in plant development and signaling. Depending on the dosage and application mode, NO and H2S can synergistically or antagonistically mediate H2O2 signaling during root development, thus enhancing tolerance to oxidative stress. This assessment provides a comprehensive update on the cooperative roles of NO and H2S in modulating H2O2 homeostasis during root development, abiotic stress tolerance, and root-microbe interaction.

Summary: Potassium (K+) plays a crucial role in plant homeostasis, and its deficiency significantly impacts photosynthesis and crop production. Under potassium starvation, multiple factors interact to reduce the photosynthetic rate and crop growth. The application of exogenous potassium can improve plant tolerance to abiotic stresses and limit the production of reactive oxygen species through activation of the antioxidant system.

Summary: The study identified 75 CaPOD genes in sweet pepper based on the existing genome, but only 10 genes were found to be active in the fruit transcriptome. Two genes were upregulated during fruit ripening, seven were downregulated, and one gene was unaffected. Nitric oxide treatment triggered the upregulation of two CaPOD genes while the others were unaffected. In vitro experiments showed that CaPOD IV activity was strongly inhibited by peroxynitrite, NO donors, and reducing agents.

Summary: NADPH is an essential cofactor involved in various physiological processes. In pepper fruits, five NADP-ME genes were identified and four of them were found to be expressed. The expression of these genes was differentially modulated during fruit ripening, with CaNADP-ME3 and CaNADP-ME5 upregulated, and CaNADP-ME2 and CaNADP-ME4 downregulated. Exogenous NO gas treatment triggered the downregulation of CaNADP-ME4. Protein fraction containing CaNADP-ME enzyme activity was obtained and four isozymes were identified.

Summary: This study investigated the interaction of iron and hydrogen sulfide (H2S) in regulating salinity tolerance in plants. The results showed that exogenous iron and H2S provided protection to tomato seedlings under salt stress by enhancing antioxidative defense, preventing membrane damage, and increasing H2S content. However, combined application of iron and H2S decreased H2S content and showed increased activity of some antioxidative enzymes in salt-stressed tomato seedlings.

Summary: Cancer, characterized by an alteration of the oxidative metabolism, is a major cause of human death worldwide. Many natural compounds from plant origin with anti-tumor attributes have been described, including capsaicin, the molecule responsible for the pungency in hot pepper fruits, which has shown anti-proliferative properties against cancer. The study found that the capsaicin content in pepper fruits did not correspond with their anti-proliferative activity, indicating the presence of other compounds with anti-tumor potentiality in pepper fruits.

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.
