About this Research Topic
A loss of soil health is one of the major constraints to achieving agricultural sustainability. This decline is frequently due to the adoption of poor agricultural practices and the excessive use of chemicals, such as fertilizers and pesticides. The application of microbial inoculants to the soil or leaves represents one alternative approach to reverse this decline in soil quality. Microbial inoculants can directly influence various plant defense mechanisms and biogeochemical processes through direct or indirect modes of action. To harness the full power of microbes within the plant-soil system necessitates that we better understand their involvement in biogeochemical cycling, and activities such as the amelioration of toxic compounds, nutrient dynamics, antioxidant activity (ROS), systematic induced resistance, suppression of pathogens, etc. Ultimately, these interactions will reduce the toxic impact of synthetic chemicals and other pollutants and will enhance product quality and environmental health.
This Research Topic will contribute to deciphering the interaction among microbes, plants, and soil for developing more eco-friendly approaches to reduce the use of chemical inputs in agriculture. This Research Topic also leads to discriminate the functional and metabolic changes that occur during interactions and their beneficial aspects. This Topic welcomes articles related to the use of microbial inoculants for improving plant health, productivity, biofortification, nutrients supply, and detoxification of harmful compounds. We encourage authors to submit original research articles describing the involvement of rhizosphere or endophytic microbes from various habitats for increasing crop productivity, biomagnifications of nutrients in soil, biofortification, improving soil health, and reducing the effect of toxic materials on plants as well as soil. Preliminary studies (include screening and observational studies) will not be considered.
Some of the main aspects of this Research Topic include, but are not limited to:
• Identification of microbial communities which have the potential to improve the availability/accumulation of nutrients in soil/plants or the detoxification of harmful compounds (i.e. heavy metals, Al, Na, organic pollutants)
• Mechanistic basis of positive interactions between microorganisms, plants, and the soil for improving nutrient use efficiency or detoxification of compounds
• Involvement of microbial metabolites for improving physiological or anatomical traits of crops, nutrients availability, accumulation of nutrients, and detoxification of compounds
• Deciphering the role of rhizospheric or endophytic microbial communities through metagenomic and other bioinformatics tools and comparative metagenomic studies
• Use of genome editing approaches for improving crop productivity and other beneficial aspects
• Development of bioinoculants of rhizospheric or endophytic microbes: use of carriers, additives, protectants, metabolites, etc.
• Novel agronomic and soil management approaches to mitigate environmental issues for improving soil health are also appreciated
