Light, water and healthy soil are three essential natural resources required for agricultural productivity. Soil Sci. In recent years, next-generation sequencing has revolutionized our understanding of microbial community composition and function, and together with improved culturing methodologies has greatly facilitated the use of biologicals in the field (Schweitzer et al., 2008; Panke-Buisse et al., 2014; Mueller and Sachs, 2015).

Therefore, it is now imperative to take advantage of this knowledge to design consortia of microbes to maintain a sustainable rhizosphere community, with key functional properties that include plant protection, nutrient acquisition, and alleviating biotic and abiotic stress responses. Soil in field plots have more complex microbial environments that are presumably adapted to the local eco-environment. (Cross-listed with GEN). Studium Press Pvt. Biochem. Our ultimate goal is to be able to shape the genetics and characteristics of useful organisms rapidly and flexibly – like clay in our hands. We hypothesize that this carbohydrate-degrading enzyme complement endows these Serendipitaceae fungi with saprotrophic abilities (Craven and Ray, 2019). Rhizosphere microbiome structure alters to enable wilt resistance in tomato. Tot. An understanding of microbial strains relevant to agricultural applications is useful in the enhancement of factors such as soil nutrients, plant-pathogen resistance, crop robustness, fertilization uptake efficiency, and more. Rhizosphere competence must be evaluated in a field situation if the true power of this approach is to be realized. Biotechnol J 12:1600099. These are just a few of the numerous applications of microbial genetics that we will explore in this chapter. (2020).

Microbiol. Microbiol. Trends Microbiol. Mycorrhizae are mutualistic associations between soil fungi and plant roots that gradually evolved to be reciprocally beneficial to both partners (Brundrett, 2002). Additionally, it is acknowledged that organically managed systems increased taxonomic and phylogenetic richness, diversity and heterogeneity of the soil microbiota when compared with conventional farming systems (Lupatini et al., 2017).

In another study, soil microbial communities of corn and switchgrass in mono-cropping systems when compared with mixed prairie grasses demonstrated that bacterial and fungal biomass, especially arbuscular mycorrhizal fungi, were higher in plots with mixed prairie grasses (Jesus et al., 2016). The abundance of endofungal bacterium Rhizobium radiobacter (syn. Chitooligomers have broad applications in industrial, agricultural and medical field and it also acts as anti-tumour agent.

Answered May 6, 2018 The application of genetics in agriculture is the main cause of sustainable and adaptable farming today in the form of new and well adapted crop species or varieties which perform better and stands well in crucial environment and soil factors. Biological control agents are Pollution free. Applications of microbes in agriculture can be studied in three different headings. (2017).

Microbes in agriculture used as- Bio-control agent. Soil is a vastly heterogeneous growth medium, providing a wide spectrum of ecological niches for microorganisms that enable diverse strains to coexist and form complex microbial communities. For example, efforts focusing on manipulating plant root exudates likely play a critical role in selective recruitment of the rhizosphere microbiome (Bakker et al., 2012). Biochem Eng 103:158–169.
