Microbial Metabolites and Redox Signaling in Plant Stress Tolerance: A step towards climate resilience

Plants are constantly exposed to various biotic and abiotic stresses, which have severely affected agricultural productivity. In recent years, research has focused on alleviating these biotic and abiotic stresses due to rapid climate change and the demand for sustainable alternatives to agrochemicals. Any stress on plants generates oxidative stress as a signalling molecule; however, the excess generation of these ROS causes acute oxidative stress in plants. The approaches of using biostimulants such as microbial inoculants, antioxidants, inducer molecules such as melatonin, etc., have direct utility in alleviating the ill effects of oxidative stress on plants. This ultimately adds to the quality and quantity of the produce. Among these, Plant Growth Promoting microorganisms (PGPMs) offer a viable, environmentally friendly way to increase plant resilience in such stressful situations through the production of natural beneficial metabolites. Since we are facing rapid changes in climatic conditions, this special issue on microbial metabolites and redox signalling is an important forum for publishing the most relevant research on plant-microbe interactions. Integration of omics approaches like molecular (genomic, transcriptomics, proteomics, metabolomics), CRISPR gene-editing tool, and marker-assisted or genome editing strategies has significantly contributed to a better understanding of bacteria-plant interactions. We encourage interdisciplinary studies that integrate approaches based on AI and machine learning. We invite high-quality original research articles, reviews, and perspectives that advance our understanding of the effects of microbial metabolites and its effects of alleviation of oxidative stress in the context of climate resilience. This collection would like to address problems like- osmotic stress, ion toxicity, hormonal imbalance, gene expression of ion channels, coordinated regulation of transcription factors, epigenetic modifications, altered root architecture, reduction in quality parameters, low productivity, stress recovery, and others.This special issue welcomes original research articles, reviews, mini-reviews, and case studies that will help advance understanding of the role of microbial-mediated redox processes in plant health, productivity, and environmental sustainability. Contributions addressing molecular mechanisms, multi-omics approaches, synthetic biology, microbial engineering, and field-scale applications are particularly encouraged.Topics of interest include, but are not limited to: Microbial bioactive metabolites, phytohormones, compatible solutes, enzymatic and non-enzymatic antioxidants, volatile organic compounds (VOCs), and other compounds having a direct impact on the stress physiology of the plants Stress signalling and Oxidative stress: Stress signalling in plants, Reactive oxygen species (ROS), Reactive nitrogen species (RNS), antioxidant defense mechanisms of plantsMicrobial regulation of induced systemic resistance and induced systemic tolerance against biotic and abiotic stresses Microbe-mediated alleviation of stresses such as drought, salinity, heat, cold, heavy metals, etc. Role of microbes in C-sequestration and other redox processes in soil.Climate-induced modulation in the structure and function of soil and plant microbiome Microbiome dynamics in rhizosphere, rhizoplane, endosphere, and phyllosphere microbiome and key stone taxaMetabolomics approaches to study plant–microbe interactions.Novel microbial metabolites for climate resilience SynCom and engineering beneficial microbes for stress alleviation Tripartite interaction of soil, plants, and microbial communities for ecosystem resilience.Climate resilience induced by biofertilizers, biostimulants, and microbial consortia Plant microbiome engineering Artificial intelligence and Machine learning for advanced plant-microbe interaction Microbial metabolites and nutrient-use efficiency.Emerging technologies for monitoring redox dynamics in plants.Bringing the technology into the field: Translational applications of plant-microbe interactionsFuture perspectives and challenges: microbial metabolite reesrah and oxidative stress amelioration Topic editors: Sukhminderjit Kaur, Pramod Kumar Sahu, Rajinder Kaur Source: https://www.frontiersin.org/research-topics/82261/microbial-metabolites-and-redox-signaling-in-plant-stress-tolerance-a-step-towards-climate-resilience
