Food security has become a major concern worldwide in recent years due to ever increasing population. Providing food for the growing billions without disturbing environmental balance is incessantly required current scenario. In view of this, sustainable modes agricultural practices offer better promise and hence are gaining prominence recently. Moreover, these methods have taken precedence currently over chemical-based pest restriction pathogen control. Adoption Biological Control one such crucial technique that forefront. Over period time, various biocontrol strategies been experimented with some exhibited great success promise. This review highlights different plant-pathogen control, types plant pathogens, their modus operandi approaches employing range microorganisms byproducts. The study lays emphasis on use upcoming methodologies like microbiome management engineering, phage cocktails, genetically modified agents microbial volatilome as available practices. More importantly, critical analysis enumerated paper indicates need amalgamate techniques order improve degree offered by them.

Emerging Pathways for Engineering the Rhizosphere Microbiome for Optimal Plant Health

Journal of Agricultural and Food Chemistry, Год журнала: 2023, Номер 71(11), С. 4441 - 4449

Опубликована: Март 8, 2023

The increasing impacts of global climate change on crop performance pose a significant threat to food security. rhizosphere microbiomes intimately interact with the plant and can largely facilitate plants in growth promotion stress resistance via multiple mechanisms. This review focuses approaches for harnessing produce beneficial effects toward enhanced productivity, including use organic inorganic amendments, microbial inoculants. Emerging methods, such as utilization synthetic consortia, host-mediated microbiome engineering, prebiotics made from specific root exudates, breeding promote plant–microbiome interactions, are highlighted. Updating our knowledge this field is critical understanding improving thereby enhancing adaptiveness changing environmental conditions.

Host-mediated microbiome engineering (HMME) of drought tolerance in the wheat rhizosphere

PLoS ONE, Год журнала: 2019, Номер 14(12), С. e0225933 - e0225933

Host-mediated microbiome engineering (HMME) is a strategy that utilizes the host phenotype to indirectly select microbiomes though cyclic differentiation and propagation. In this experiment, of delayed onset seedling water deficit stress symptoms was used infer beneficial microbiome-host interactions over multiple generations. By utilizing host-centric selection approach, microbiota are selected at community level, therein using artificial alter through both ecological evolutionary processes. After six rounds host-mediated (HMME), microbial mediated 5-day delay in drought wheat seedlings. Seedlings grown potting medium inoculated with engineered rhizosphere from 6th round HMME produced significantly more biomass root system length, dry weight, surface area than plants similarly mixed autoclaved inoculum (negative control). The effect on plant tolerance conferred by transferable subsequent 10-fold 100-fold dilutions fresh non-autoclaved but lost 1000-fold dilution completely abolished autoclaving, indicating population dynamics. results 16S rRNA amplicon sequencing 0, 3, 6 revealed taxonomic increases proteobacteria phylum level betaproteobacteria class level.

Directed Evolution of Microbial Communities

Annual Review of Biophysics, Год журнала: 2021, Номер 50(1), С. 323 - 341

Опубликована: Март 1, 2021

Directed evolution is a form of artificial selection that has been used for decades to find biomolecules and organisms with new or enhanced functional traits. can be conceptualized as guided exploration the genotype-phenotype map, where genetic variants desirable phenotypes are first selected then mutagenized search genotype space an even better mutant. In recent years, idea applying microbial communities gained momentum. this article, we review main limitations when applied large diverse collectives asexually dividing microbes discuss how tools directed may deployed engineer from top down. We conceptualize ecological structure-function landscape propose practical guidelines navigating these landscapes.

Artificial Selection on Microbiomes To Breed Microbiomes That Confer Salt Tolerance to Plants

We develop a method to artificially select for rhizosphere microbiomes that confer salt tolerance the model grass Brachypodium distachyon grown under sodium stress or aluminum stress. In controlled greenhouse environment, we differentially propagated between plants of nonevolving, highly inbred plant population; therefore, only evolved in our experiment, but did not evolve parallel. To maximize microbiome perpetuation when transplanting and, thus, response selection, improved earlier methods by (i) controlling assembly inoculating seeds at beginning each selection cycle; (ii) fractionating before transfer harvest, perpetuate, and on bacterial viral components; (iii) ramping gradually from minor extreme with cycle minimize chance overstressing plants; (iv) using two nonselection control treatments (e.g., microbial enrichment null inoculation) permit comparison improving fitness benefits selected impart plants.
