Unfortunately, only a few agroecosystem experiments exist that compare organic and conventional management strategies over an extended period for evaluation of impact on soil health and restoration (Raupp et al., 2006; Khatoon et al., 2020). Surv. Weather Clim Extrem 10:4–10. 624, 407–415. Mycorrhizal microbiomes. Early research in unfertilized grasslands demonstrated that fungal communities respond positively to plant-derived C inputs, suggesting that inclusion of cover crops in a rotation may promote fungal community development (Denef et al., 2009). Plant genetics remains a key component of global food security, peace, and prosperity for the foreseeable future. Ecol. The mycobiota: fungi take their place between plants and bacteria. Class. More than Serendipity: The Potential to Manage Soil Carbon and Emissions While Promoting Low-Input Agriculture with Serendipitoid Mycorrhizae. In addition to that, new scientific methodologies that can track the nutrient flux through the plant, its resident microbiome and surrounding soil, will offer new opportunities for the design of more efficient microbial consortia design. Bacterial diversity in soils subjected to long-term chemical fertilization can be more stably maintained with the addition of livestock manure than wheat straw. doi: 10.1264/jsme2.me3304rh, Tsolakidou, M.-D., Stringlis, I.

The next-generation sequencing technologies have exhibited that only a small portion of microorganisms could be cultivated until now. (2014). Biochemistry and physiology: Scientists are trying to design microbes that will perform reliably and target specific plant/microbe interactions. doi: 10.1016/j.soilbio.2015.07.021, Guo, H., Glaeser, S. P., Alabid, I., Imani, J., Haghighi, H., Kämpfer, P., et al. Unlike arbuscular mycorrhizae, which exchange inorganic, mineralized nutrients mined from the soil for carbon derived from host photosynthesis, members of the Serendipitaceae studied thus far have a complete arsenal of carbohydrate-active enzymes (CAZymes), representing approximately 4% of the entire gene set and rivaling the more well-studied saprophytic white and brown wood rotters, and much more than other symbiotic fungi. Thus, it can arguably be stated that the diversity of a microbial inoculum, in addition to its plant growth-promoting traits, is critical for enhancing productivity and longevity (Cordero and Polz, 2014). Cover crop and irrigation effects on soil microbial communities and enzymes in semiarid agroecosystems of the Central Great Plains of North America. Presumably, this saved carbon could potentially be used for other symbiotic relationships or developmental processes. Pathology applications • Biomarkers to assess patients at risk of recurrence, predict successful therapy • Stool-based analytes vs microbial community signatures • As blood banks manage blood transfusion will micro labs manage therapeutic microbial communities, whether from vendor or in-house sources. Cropping practices manipulate abundance patterns of root and soil microbiome members paving the way to smart farming. Additionally, suppressive samples showed greater expression of polyketide cyclase, terpenoid biosynthesis, and cold shock proteins (Hayden et al., 2018). doi: 10.1016/j.chom.2017.07.004, Wallenstein, M. D. (2017). Therefore, specific traits of a plant that modulate its microbiome should be considered as a trait for plant breeding (Wallenstein, 2017). doi: 10.1111/1462-2920.14824, Liu, Y., Zhu, A., Tan, H., Cao, L., and Zhang, R.

Biological control of plant pathogens. Consequently, researchers working with specific plant-microbe interactions have increasingly acknowledged the mitigating impact these larger microbial communities have on individual plant-microbe outcomes for plant growth promotion or fitness. 117, 1148–1159.

Phytobio. Microbiol. In 1904, the German agronomist and plant physiologist Lorenz Hiltner coined the term rhizosphere (Hartmann et al., 2008) to describe the area around a plant root inhabited by a unique population of microorganisms.

Example: Green … For example, sequential inoculation of nitrogen fixing bacterium Azotobacter vinelandii, followed by plant growth-promoting root-endophytic fungus Serendipita indica demonstrated better growth in rice (Dabral et al., 2020). However, studies of natural populations suggest that groups of microbes with distinct function niches play pivotal roles in adhering and desorbing inorganic nutrients to physical surfaces, as well as breaking down organic residues and incorporating them into the soil (Lakshmanan et al., 2014; Finkel et al., 2017; Kumar and Dubey, 2020).

Several studies reported increases in such soil quality parameters as organic matter content, microbial biomass and respiration under crop rotation management when compared with a mono-cropping system (Campbell et al., 1991; Luce et al., 2013). 150, 222–233. 11:622926. doi: 10.3389/fmicb.2020.622926.

Bashan Y, Holguin G (1998) Proposal for the division of plant growth-promoting rhizobacteria into two classifications: biocontrol-PGPB (plant growth-promoting bacteria) and PGPB. Am. Microbial genetics has played a unique role in developing the fields of molecular and cell biology and also has found applications in medicine, agriculture, and the food and pharmaceutical industries. Conceptually, this increases the relative abundance of a given beneficial microbe in the rhizosphere, at least temporarily, to achieve the desired benefit. Fertilization and the response of the soil microbial community to the process significantly affect crop yield and the environment. Microbiol. (2020). Microbiol. Environ, Microbiol. The Minor in Plant, Animal and Microbial Biotechnology is available as an elective to students who are enrolled in Bachelor of Science degree programs with majors in animal science, biosystems engineering, fisheries and wildlife, food science, forestry, horticulture, and plant, soil and microbial sciences. Successive passaging of a plant-associated microbiome reveals robust habitat and host genotype-dependent selection. Thus, in addition to establishment of a compatible interaction with the host, a successful microbial inoculant has to subsequently compete and persist in the context of indigenous microbes as well as local abiotic conditions (Finkel et al., 2017). Tringe SG, Hugenholtz P (2008) A renaissance for the pioneering 16S rRNA gene. In any case, these intriguing fungi and their seemingly unlimited host range provide a novel symbiosis that could be used in a broad variety of cropping systems. Proc. (2020). Part of Springer Nature. Nonetheless, very few studies have assessed the relationship between cover crop stands and their associated belowground microbial communities. (2015). To date, several microbial genera have been proposed as key players in disease suppressiveness of soils, but the complexity of the microbiome, as well as the underlying mechanisms and microbial traits, remain elusive for most disease suppressive soils (Toyota and Shirai, 2018). 100, 9331–9341. Springer Plus 3:208. Soil organic matter turnover is thus considered a net positive, as it liberates the nutrients locked up in organic matter. A 16S amplicon-based metagenomic analysis of an almost 20-year-old field trial in Bernburg, Germany revealed a significant effect of tillage practice and the preceding crop on prokaryotic community structures (Babin et al., 2019).
