Summary: Reactive oxygen/nitrogen species (ROS/RNS) play crucial roles in signal transduction processes that regulate plant responses to climate extremes. They function as signaling molecules/components to promote plant growth and development. This review provides an overview of the production and signaling mechanisms of ROS/RNS in different subcellular compartments in plants, highlighting their roles in regulating plant immune response under stress conditions. It also discusses the integration of ROS/RNS with phytohormones and other signaling components to modulate stress-responsive genes/transcription factors for plant growth and development.

Summary: Plant growth and productivity are negatively affected by abiotic and biotic stresses. Recent research has shown that reactive oxygen, nitrogen, and sulfur species are involved in activating signaling networks that regulate stress defense and survival mechanisms. However, the molecular mechanisms underlying their effects are still unclear.

Summary: Reactive oxygen species (ROS) and reactive nitrogen species (RNS) play crucial roles as signaling molecules in the cell systems of plants, especially under stress conditions. They control plant growth, development, symbiotic association, and defense mechanisms in response to both biotic and abiotic stresses, but excessive accumulation of ROS and RNS can lead to cell damage and hinder plant growth. This review focuses on the production and elimination of ROS and RNS, their functions as signaling molecules during plant-microbe interactions, and the antioxidant system as a balancing mechanism.

Summary: The impact of climate change on plants leads to a variety of stresses, and plants employ multiple mechanisms to improve their survival rate under extreme conditions. Among these mechanisms, the overproduction of molecular reactive species plays a crucial role. Studies have shown that the post-translational modifications induced by these stresses affect the enzymatic activity, thus regulating the metabolic pathways involved in plant adaptation and tolerance. This review summarizes recent research on post-translational modifications in plants, with a focus on the role of these modifications in plant adaptation to abiotic stresses.

Summary: Manipulating the balance between anthocyanins and reactive oxygen species (ROS) can enhance plant productivity, nutritional value, and stress resistance. Anthocyanins are water-soluble pigments found in most flowering plants, and their chemistry, biosynthesis, and functions have been extensively studied for their health benefits. While antioxidants like anthocyanins can remove excessive ROS, allowing ROS to trigger important cellular signaling pathways is also crucial for plant growth and stress responses. This article explores the interaction between anthocyanins and ROS and highlights the potential benefits of understanding their balance for improving plant traits and maintaining proper cellular function.

Summary: Melanoma is a highly aggressive cancer with activating mutations in BRAF being the most common genetic alterations. Targeted inhibitors have improved survival rates in advanced melanoma patients, but resistance still develops in around 50% of patients within the first year of therapy, presenting a significant challenge in managing BRAF-mutated advanced melanoma. Understading the mechanisms of resistance, including genetic, epigenetic, and oxidative stress-related factors, is crucial in developing effective therapies.

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: This study demonstrates the high nodulation competitiveness of two strains with intermediate nitrogen fixation capacity in Trifolium repens. It also identifies Rhizobium redzepovicii as a T. repens symbiont for the first time. The transfer of symbiotic genes from efficient to inefficient strains is observed, leading to strains with intermediate efficiency. These findings emphasize the importance of seed inoculation in improving clover yields and mitigating the effect of parasitic and low-efficiency strains in soils.

Summary: Plant susceptibility to salt depends on genetic and physiological factors. In this study, lemongrass plants were treated with chitosan oligomers (COS) to alleviate salinity stress and improve growth and essential oil production. Results showed that COS enhanced photosynthesis, antioxidant defence, stomatal conductance, and overall plant development. The treatment also increased geraniol dehydrogenase activity and lemongrass essential oil production. The findings suggest that COS can be a useful tool for improving crop productivity in saline soil and promoting alternative crops for saline lands.

Summary: This study investigates the interaction between zinc and cadmium in rice roots and how zinc can protect plants from cadmium stress. The results show that zinc can reduce cadmium accumulation in roots and increase its own accumulation, leading to reduced oxidative stress through modulation of gene expression. These findings are important for improving rice varieties to maintain crop productivity in cadmium-contaminated areas.
