Developing climate‐resilient crops: improving plant tolerance to stress combination

The Plant Journal, Journal Year: 2021, Volume and Issue: 109(2), P. 373 - 389

SUMMARY Global warming and climate change are driving an alarming increase in the frequency intensity of different abiotic stresses, such as droughts, heat waves, cold snaps, flooding, negatively affecting crop yields causing food shortages. Climate is also altering composition behavior insect pathogen populations adding to yield losses worldwide. Additional constraints agriculture caused by increasing amounts human‐generated pollutants, well negative impact on soil microbiomes. Although laboratory, we trained study individual stress conditions plants, field many pests could simultaneously or sequentially affect combination. Because expected combination events (e.g., waves combined with drought, other and/or pathogens), a concentrated effort needed how crops. This need particularly critical, studies have shown that response plants unique cannot be predicted from simply studying each stresses part Strategies enhance tolerance particular may therefore fail this specific stress, when factors.

Disruption of Firmicutes and Actinobacteria abundance in tomato rhizosphere causes the incidence of bacterial wilt disease

The ISME Journal, Journal Year: 2020, Volume and Issue: 15(1), P. 330 - 347

Published: Oct. 7, 2020

Enrichment of protective microbiota in the rhizosphere facilitates disease suppression. However, how disruption rhizobacteria affects suppression is largely unknown. Here, we analyzed microbial community a healthy and diseased tomato plant grown <30-cm apart greenhouse at three different locations South Korea. The abundance Gram-positive Actinobacteria Firmicutes phyla was lower soil (DRS) than (HRS) without changes causative Ralstonia solanacearum population. Artificial bacteria HRS using 500-μg/mL vancomycin increased bacterial wilt occurrence tomato. To identify HRS-specific plant-protective species, Brevibacterium frigoritolerans HRS1, Bacillus niacini HRS2, Solibacillus silvestris HRS3, luciferensis HRS4 were selected from among 326 heat-stable culturable isolates. These four strains did not directly antagonize R. but activated immunity. A synthetic comprising these displayed greater immune activation against extended protection by 4 more days comparison with each individual strain. Overall, our results demonstrate for first time that dysbiosis DRS promotes incidence disease.

Tailoring plant-associated microbial inoculants in agriculture: a roadmap for successful application

Journal of Experimental Botany, Journal Year: 2020, Volume and Issue: 71(13), P. 3878 - 3901

Published: March 9, 2020

Abstract Plants are now recognized as metaorganisms which composed of a host plant associated with multitude microbes that provide the variety essential functions to adapt local environment. Recent research showed remarkable importance and range microbial partners for enhancing growth health plants. However, plant–microbe holobionts influenced by many different factors, generating complex interactive systems. In this review, we summarize insights from emerging field, highlighting factors contribute recruitment, selection, enrichment, dynamic interactions plant-associated microbiota. We then propose roadmap synthetic community application aim establishing sustainable agricultural systems use communities enhance productivity plants independently chemical fertilizers pesticides. Considering global warming climate change, suggest desert can serve suitable pool potentially beneficial maintain under abiotic stress conditions.

Microbe to Microbiome: A Paradigm Shift in the Application of Microorganisms for Sustainable Agriculture

Frontiers in Microbiology, Journal Year: 2020, Volume and Issue: 11

Published: Dec. 21, 2020

Light, water and healthy soil are three essential natural resources required for agricultural productivity. Industrialization of agriculture has resulted in intensification cropping practices using enormous amounts chemical pesticides fertilizers that damage these resources. Therefore, there is a need to embrace do not depend on greater use meet the growing demand global food requirements. Plants harbor millions microorganisms, which collectively form microbial community known as microbiome. An effective microbiome can offer benefits its host, including plant growth promotion, nutrient efficiency, control pests phytopathogens. an immediate bring functional potential plant-associated innovation into crop production. In addition that, new scientific methodologies track flux through plant, resident surrounding soil, will opportunities design more efficient consortia design. It now increasingly acknowledged diversity inoculum important promoting ability. Not surprisingly, outcomes from such studies have paradigm shift away single, specific microbes holistic approach enhancing productivity restoration health. Herein, we reviewed this discussed various aspects benign microbiome-based approaches sustainable agriculture.

The rhizosphere microbiome plays a role in the resistance to soil-borne pathogens and nutrient uptake of strawberry cultivars under field conditions

Scientific Reports, Journal Year: 2021, Volume and Issue: 11(1)

Published: Feb. 4, 2021

Microbial-root associations are important to help plants cope with abiotic and biotic stressors. Managing these interactions offers an opportunity for improving the efficiency sustainability of agricultural production. By characterizing bacterial archaeal community (via 16S rRNA sequencing) associated bulk rhizosphere soil sixteen strawberry cultivars in two controlled field studies, we explored relationships between microbiome plant resistance soil-borne fungal pathogens (Verticillium dahliae Macrophomina phaseolina). Overall, had a distinctive genotype-dependent higher abundances known beneficial bacteria such as Pseudomonads Rhizobium. The played significant role shown by differences high low cultivars. Resistant were characterized biocontrol microorganisms including actinobacteria (Arthrobacter, Nocardioides Gaiella) unclassified acidobacteria (Gp6, Gp16 Gp4), both pathogen trials. Additionally, that resistant V.

A holistic framework integrating plant-microbe-mineral regulation of soil bioavailable nitrogen

Biogeochemistry, Journal Year: 2021, Volume and Issue: 154(2), P. 211 - 229

Published: May 6, 2021

Soil organic nitrogen (N) is a critical resource for plants and microbes, but the processes that govern its cycle are not well-described. To promote holistic understanding of soil N dynamics, we need an integrated model links matter (SOM) cycling to bioavailable in both unmanaged managed landscapes, including agroecosystems. We present framework unifies recent conceptual advances our three steps cycling: (ON) depolymerization solubilization; sorption desorption on mineral surfaces; microbial ON turnover assimilation, mineralization, recycling products. Consideration balance between these provides insight into sources, sinks, flux rates N. By accounting interactions among biological, physical, chemical controls over availability complex mechanisms transformation concrete amenable experimental testing translates ideas new management practices. This will allow researchers practitioners use common measurements particulate (POM) mineral-associated (MAOM) design strategic N-cycle interventions optimize ecosystem productivity minimize environmental loss.The online version contains supplementary material available at 10.1007/s10533-021-00793-9.
