Plants have evolved with a plethora of microorganisms having important roles for plant growth and health. A considerable amount information is now available on the structure dynamics microbiota as well functional capacities isolated community members. Due to interesting potential due current challenges in crop production there an urgent need bring microbial innovations into practice. Different approaches microbiome improvement exist. On one hand strains or strain combinations can be applied, however, field success often variable urgently required. Smart, knowledge-driven selection needed use suitable delivery formulations. other hand, farming practices genotype influence thus functioning. Therefore, appropriate breeding leading improved plant-microbiome interactions are avenues increase benefit microbiota. In conclusion, different making new generation inoculants application microbiome-based agro-management lines could lead better microbiome.

The quest for enhancing agricultural yields due to increased pressure on food production has inevitably led the indiscriminate use of chemical fertilizers and other agrochemicals. Biofertilizers are emerging as a suitable alternative counteract adverse environmental impacts exerted by synthetic facilitate overall growth yield crops in an eco-friendly manner. They contain living or dormant microbes, which applied soil used treating crop seeds. One foremost candidates this respect is rhizobacteria. Plant promoting rhizobacteria (PGPR) important cluster beneficial, root-colonizing bacteria thriving plant rhizosphere bulk soil. exhibit synergistic antagonistic interactions with microbiota engage array activities ecological significance. promote facilitating biotic abiotic stress tolerance support nutrition host plants. Due their active endorsing activities, PGPRs considered hazardous fertilizers. biofertilizers biological approach toward sustainable intensification agriculture. However, application increasing several pros cons. Application potential that perform well laboratory greenhouse conditions often fails deliver expected effects development field settings.

Recent Understanding of Soil Acidobacteria and Their Ecological Significance: A Critical Review

Frontiers in Microbiology, Год журнала: 2020, Номер 11

Опубликована: Окт. 30, 2020

Acidobacteria represents an underrepresented soil bacterial phylum whose members are pervasive and copiously distributed across nearly all ecosystems. Acidobacterial sequences abundant in soils represent a significant fraction of microbial community. Being recalcitrant difficult-to-cultivate under laboratory conditions, holistic, polyphasic approaches required to study these refractive bacteria extensively. possesses inventory genes involved diverse metabolic pathways, as evidenced by their pan-genomic profiles. Because preponderance ubiquity the soil, speculations have been made regarding dynamic roles vital ecological processes viz., regulation biogeochemical cycles, decomposition biopolymers, exopolysaccharide secretion, plant growth promotion. These expected that might help survival competitive colonization rhizosphere, leading establishment beneficial relationships with plants. Exploration genetic attributes more in-depth insights into belowground mechanics dynamics would lead better understanding functions significance this enigmatic soil-plant environment. This review is effort provide recent update diversity useful for characterization, roles, future biotechnological perspectives.

Biological Control of Plant Pathogens: A Global Perspective

Microorganisms, Год журнала: 2022, Номер 10(3), С. 596 - 596

Опубликована: Март 9, 2022

The increase in the world population has generated an important need for both quality and quantity agricultural products, which led to a significant surge use of chemical pesticides fight crop diseases. Consumers, however, have become very concerned recent years over side effects fungicides on human health environment. As result, research into alternative solutions protect crops been imposed attracted wide attention from researchers worldwide. Among these alternatives, biological controls through beneficial microorganisms gained considerable importance, whilst several control agents (BCAs) screened, among them Bacillus, Pantoea, Streptomyces, Trichoderma, Clonostachys, Pseudomonas, Burkholderia, certain yeasts. At present, biopesticide products developed marketed either leaf diseases, root or fruit storage However, no positive correlation observed between number screened BCAs available products. Therefore, this review emphasizes development biofungicides screening marketing problems that hinder their development. Finally, particular was given gaps sector factors hamper its development, particularly terms efficacy legislation procedures.

Soil microbiota as game-changers in restoration of degraded lands

Science, Год журнала: 2022, Номер 375(6584)

Опубликована: Март 3, 2022

Land degradation reduces soil functioning and, consequently, the services that provides. Soil hydrological functions are critical to combat and promote restoration. microorganisms affect hydrology, but role of microbiota in forming sustaining is not well explored. Case studies indicate potential as game-changers restoring functions. We review state art microorganism use land restoration technology, groups with greatest for restoration, knowledge effect on physical properties, proposed strategies long-term degraded lands. also emphasize need advance emerging research field biophysical landscape interactions support soil-plant ecosystem practices.

Systems Biology of Plant-Microbiome Interactions

Molecular Plant, Год журнала: 2019, Номер 12(6), С. 804 - 821

Опубликована: Май 23, 2019

In natural environments, plants are exposed to diverse microbiota that they interact with in complex ways. While plant–pathogen interactions have been intensely studied understand defense mechanisms plants, many microbes and microbial communities can substantial beneficial effects on their plant host. Such include improved acquisition of nutrients, accelerated growth, resilience against pathogens, resistance abiotic stress conditions such as heat, drought, salinity. However, the bacterial strains or consortia host often cultivar species specific, posing an obstacle general application. Remarkably, signals trigger immune responses molecularly highly similar identical pathogenic microbes. Thus, it is unclear what determines outcome a particular microbe–host interaction which factors enable distinguish beneficials from pathogens. To unravel network genetic, microbial, metabolic interactions, including signaling events mediating comprehensive quantitative systems biology approaches will be needed.

The rhizosphere is undoubtedly the most complex microhabitat, comprised of an integrated network plant roots, soil, and a diverse consortium bacteria, fungi, eukaryotes, archaea. conditions have direct impact on crop growth yield. Nutrient-rich environments stimulate yield vice versa. Extensive cultivation exhaust soils which need to be nurtured before or during next crop. Chemical fertilizers are major source nutrients but their uncontrolled widespread usage has posed serious threat sustainability agriculture stability ecosystem. These chemicals accumulated in drained water, emitted air where they persist for decades causing overall Plant growth-promoting rhizobacteria (PGPR) present convert many plant-unavailable essential e.g., nitrogen, phosphorous, zinc, etc. into available forms. PGPR produces certain hormones (such as auxin, cytokinin, gibberellin), cell lytic enzymes (chitinase, protease, hydrolases, etc.), secondary metabolites, antibiotics, stress alleviating compounds (e.g., 1-Aminocyclopropane-1- carboxylate deaminase), chelating agents (siderophores), some signaling N-Acyl homoserine lactones) interact with beneficial pathogenic counterparts rhizosphere. multifarious activities improve soil structure, health, fertility, functioning directly indirectly support under normal stressed environments.
