Environmental stresses are undoubtedly one of the biggest problems in modern agriculture today. As pointed out by scientists, stress causes 10% of crop damage and is expected to increase by 50% by the year 2050. Much research is underway to understand the interplay between plant life and microbes. Studies show that there are good microbes that reduce stress in plants and increase the yield of farm crops. In addition to interacting with plants, microbially mediated communities such as rhizobacteria, mycorrhizal fungi (P. indica), and endophytes like microbes associated with the plant make a great alliance that builds tolerance mechanisms more robust, promote the activities, and raise the release of plant beneficial hormones such as jasmonic acid and gibberellin, which in turn promote the growth and productivity of plants as well as root proliferation, facilitating enhanced nutrition by increasing soil nutrients, water efficiency, and tolerance to non-biological stresses, such as drought, salinity, and extreme temperature. Additionally, these microbes associated with plants can boost their defense against pathogens. Therefore, this will reduce the adverse effects of such organisms on plants and consequently reduce the need for chemical treatments on plants, which otherwise would be necessary and leave behind harmful residues that are biologically undecomposable. It has been well demonstrated that plant growth-promoting rhizobacteria (PGPRs) and other microbial inoculants can increase crop yields in areas of limited resources through the use of plant growth-promoting rhizobacteria (PGPRs). PGPR is utilized in agricultural technologies like CRISPR and synthetic biology (synBio), and in other related fields, it has dramatically enhanced plant survival in the direction of environmental modifications in attaining sustainable agriculture. In this book chapter review, we had explored the biotic and abiotic stress-tolerant significant microbes and their modes of action to augment the sustainability of agricultural crop production.

摘要

Environmental stresses are undoubtedly one of the biggest problems in modern agriculture today. As pointed out by scientists, stress causes 10% of crop damage and is expected to increase by 50% by the year 2050. Much research is underway to understand the interplay between plant life and microbes. Studies show that there are good microbes that reduce stress in plants and increase the yield of farm crops. In addition to interacting with plants, microbially mediated communities such as rhizobacteria, mycorrhizal fungi (P. indica), and endophytes like microbes associated with the plant make a great alliance that builds tolerance mechanisms more robust, promote the activities, and raise the release of plant beneficial hormones such as jasmonic acid and gibberellin, which in turn promote the growth and productivity of plants as well as root proliferation, facilitating enhanced nutrition by increasing soil nutrients, water efficiency, and tolerance to non-biological stresses, such as drought, salinity, and extreme temperature. Additionally, these microbes associated with plants can boost their defense against pathogens. Therefore, this will reduce the adverse effects of such organisms on plants and consequently reduce the need for chemical treatments on plants, which otherwise would be necessary and leave behind harmful residues that are biologically undecomposable. It has been well demonstrated that plant growth-promoting rhizobacteria (PGPRs) and other microbial inoculants can increase crop yields in areas of limited resources through the use of plant growth-promoting rhizobacteria (PGPRs). PGPR is utilized in agricultural technologies like CRISPR and synthetic biology (synBio), and in other related fields, it has dramatically enhanced plant survival in the direction of environmental modifications in attaining sustainable agriculture. In this book chapter review, we had explored the biotic and abiotic stress-tolerant significant microbes and their modes of action to augment the sustainability of agricultural crop production.
