Plant growth-promoting microorganisms as biocontrol agents of plant diseases: Mechanisms, challenges and future perspectives

Frontiers in Plant Science, Journal Year: 2022, Volume and Issue: 13

Published: Oct. 6, 2022

Plant diseases and pests are risk factors that threaten global food security. Excessive chemical pesticide applications commonly used to reduce the effects of plant caused by bacterial fungal pathogens. A major concern, as we strive toward more sustainable agriculture, is increase crop yields for increasing population. Microbial biological control agents (MBCAs) have proved their efficacy be a green strategy manage diseases, stimulate growth performance, yield. Besides role in enhancement, growth-promoting rhizobacteria/fungi (PGPR/PGPF) could suppress producing inhibitory chemicals inducing immune responses plants against phytopathogens. As biofertilizers biopesticides, PGPR PGPF considered feasible, attractive economic approach agriculture; thus, resulting “win-win” situation. Several strains been identified effective BCAs under environmentally controlled conditions. In general, any MBCA must overcome certain challenges before it can registered or widely utilized diseases/pests. Successful MBCAs offer practical solution improve greenhouse performance with reduced fertilizer inputs applications. This current review aims fill gap knowledge microorganisms (PGPM), provide attention about scientific basis policy development, recommend further research related PGPM commercial purposes.

Crop disease remains a major problem to global food production. Excess use of pesticides through chemical control measures is serious for sustainable agriculture as we struggle higher crop productivity. The plant growth promoting rhizobacteria (PGPR) proven environment friendly way controlling and increasing yield. PGPR suppress diseases by directly synthesizing pathogen-antagonizing compounds, well triggering immune responses. It possible identify develop that both more stimulate growth, bringing dual benefit. A number have been registered commercial under greenhouse field conditions large strains identified proved effective biocontrol agents (BCAs) environmentally controlled conditions. However, there are still challenges before registration, large-scale application, adoption the pest management. Successful BCAs provide strong theoretical practical support application in production, which ensures feasibility efficacy horticulture This could be pave widespread agriculture, including conditions, assist with management climate change

Endophytic bacteria are mainly present in the plant’s root systems. improve plant health and sometimes necessary to fight against adverse conditions. There is an increasing trend for use of bacterial endophytes as bio-fertilizers. However, new challenges also arising regarding management these newly discovered endophytes. Plant growth-promoting exist a wide host range part their microbiome, proven exhibit positive effects on growth. communities within hosts dynamic affected by abiotic/biotic factors such soil conditions, geographical distribution, climate, species, plant-microbe interaction at large scale. Therefore, there need evaluate mechanism endophytes’ with plants under field conditions before application. Bacterial have both beneficial harmful impacts but exact poorly understood.

The soil microbiome plays an important role in maintaining health, plant productivity, and ecosystem services. Current molecular-based studies have shed light on the fact that has been quantitatively underestimated. In addition to metagenomic studies, metaproteomics metatranscriptomic target functional part of are becoming more common. These for a better understanding deciphering plant-microbe interactions. Free-living beneficial bacteria promote growth by colonizing roots called growth-promoting rhizobacteria (PGPRs). They exert their effects different ways, either facilitating uptake nutrients synthesizing particular compounds plants or preventing protecting from diseases. A interactions both natural agroecosystems will offer us biotechnological tool managing fertility obtaining high-yield food production system.

Influence of microbial inoculants on co-composting of lignocellulosic crop residues with farm animal manure: A review

Journal of Environmental Management, Journal Year: 2021, Volume and Issue: 302, P. 114088 - 114088

Published: Nov. 16, 2021

The rapidly developing agro-industry generates huge amounts of lignocellulosic crop residues and animal manure worldwide. Although co-composting represents a promising cost-effective method to treat various agricultural wastes simultaneously, poor composting efficiency prolongs total completion time deteriorates the quality final product. However, supplementation feedstock with beneficial microorganisms can mitigate these negative effects by facilitating decomposition recalcitrant materials, enhancing microbial enzyme activity, promoting maturation humus formation during process. Nevertheless, influence inoculation may vary greatly depending on certain factors, such as start-up parameters, structure feedstock, inoculation, composition cultures used. purpose this contribution is review recent developments in procedures involving different farm combined strategies. To evaluate effectiveness additives, results reported large number peer-reviewed articles were compared terms process parameters (i.e., temperature, organic carbon nitrogen contents, rate lignocellulose fractions, etc.) compost characteristics (humification, C/N ratio, macronutrient content, germination index). Most studies confirmed that use amendments an efficient way facilitate biodegradation improve sustainable management wastes. Overall, paper provides insights into techniques, identifies limitations current challenges co-composting, especially recommends areas for further research field.
