To date, an understanding of how plant growth-promoting bacteria facilitate growth has been primarily based on studies individual interacting with plants under different conditions. More recently, it become clear that specific soil microorganisms interact one another in consortia the collective being responsible for positive effects growth. Different attract cross-sections and fungi soil, initially composition unique root exudates from each plant. Thus, mostly those are beneficial to exclude potentially pathogenic. Beneficial bacterial not only help promote growth, these also protect a wide range direct indirect environmental stresses. Moreover, is currently possible engineer seeds contain desired strains thereby benefit next generation plants.

Application of Synthetic Consortia for Improvement of Soil Fertility, Pollution Remediation, and Agricultural Productivity: A Review

Agronomy, Journal Year: 2023, Volume and Issue: 13(3), P. 643 - 643

Published: Feb. 23, 2023

Climate change, inadequate possessions, and land degradation all pose obstacles to modern agriculture. In the current scenario, agriculture industry is mainly dependent on use of chemical-based pesticides fertilizers that impact soil health crop productivity. Moreover, water scarcity leads farmers in drastically affected regions heavy metal-enriched sources originating from industrial for field crops irrigation. Soil pollutants can be carried into human body via dust water, creating negative effects varying simple symptoms, e.g., nausea diarrhea reaching death critical cases. Thus, clean contaminants, improve fertility agricultural production, alternatives chemical must developed. Therefore, using beneficial microbes found plant-associated microorganisms offers an effective strategy alleviate some these challenges, improving fertility, yield, protecting plants stress conditions. Through synergistic interactions, synthetic consortium seeks stability microbial communities. this review, consortia their potential were discussed. Further, engineering new was suggested as approach concept environmental bioremediation contaminants.

Efforts towards overcoming drought stress in crops: Revisiting the mechanisms employed by plant growth-promoting bacteria

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: July 29, 2022

Globally, agriculture is under a lot of pressure due to rising population and corresponding increases in food demand. However, several variables, including improper mechanization, limited arable land, the presence biotic abiotic pressures, continually impact agricultural productivity. Drought notable destructive stress may be most serious challenge confronting sustainable agriculture, resulting significant crop output deficiency. Numerous morphological physiological changes occur plants as result drought stress. Hence, there need create mitigation techniques since these might permanently harm plant. Current methods used reduce effects include use film farming, super-absorbent hydrogels, nanoparticles, biochar, drought-resistant plant cultivars. activities are money labor-intensive, which offer improvement. The plant-growth-promoting bacteria (PGPB) has proven preferred method that offers indirect direct advantages mitigation. PGPB critical biological elements have favorable impacts on plants’ biochemical features, leading improved sugar production, relative water content, leaf number, ascorbic acid levels, photosynthetic pigment quantities. This present review revisited ameliorating detrimental plants, explored mechanism action employed, well major challenges encountered their application for growth development.

Microbial consortium inoculation has been proposed as a natural-based strategy to safeguard multiple ecosystem services. Still, its observed effects and comparisons single-species have yet be systematically quantified. In this global meta-analysis of 51 live-soil studies (carefully selected from pool 2149 studies), we compared the impact (mean variability) inoculations on biofertilization bioremediation. Our results showed that both increased plant growth by 29 % 48 %, respectively, pollution remediation 80 with non-inoculated treatments. We revealed diversity inoculants synergistic effect between frequently used inoculums (e.g., Bacillus Pseudomonas) contributed effectiveness inoculation. Despite reduction in efficacy field settings greenhouse results, had more significant overall advantage under various conditions. recommend increasing original soil organic matter, available N, P content regulating pH 6–7 achieve better effect.
