Non-native PGPB consortium consisting of Pseudomonas sp. G31 and Azotobacter sp. PBC2 promoted winter wheat growth and slightly altered the native bacterial community

Plant growth-promoting bacteria (PGPB) are considered an effective eco-friendly biostimulator. However, relatively few studies have examined how PGPB affect the native bacterial community of major crops. Thus, this study investigates impact a consortium, comprising Pseudomonas sp. G31 and Azotobacter PBC2 (P1A), on soil wheat under field conditions. As result application, we observed significant increase in seed yield, as well nitrate content (1st 3rd time points) available phosphorus (2nd point) rhizosphere compared to control. For metataxonomic study, Next-Generation Sequencing was performed using Illumina NovaSeq 6000 system. The consortium used did not diversity slightly affected taxonomic composition with no changes dominants at phylum genus level. Nevertheless, 3 weeks after P1A increased relative abundance Nitrospira which could influenced nitrates rhizosphere, also decreased Bdellovibrio. results indicate that due its ability promote plant growth without detrimental alternations soil, may be potential candidate for commercialization.

Crop rotation and a rye cover crop have minor impacts on soil health, microbial communities, and soybean yield in Ohio

Frontiers in Soil Science, Journal Year: 2025, Volume and Issue: 5

Published: March 4, 2025

Crop rotations in the Midwest U.S. have become less diversified over last twenty years while at same time cover crop acreage has increased. The impact of these changes on soil health and microbial communities is not entirely understood. In rotational plots two sites Ohio, we investigated a corn-soy-wheat rotation rye carbon, nitrogen, organic matter, their relationships with soybean yield. Rhizosphere fungal, arbuscular mycorrhizal bacterial were also assessed, as well yield parameters. Microbial measured using long short-read amplicon sequencing PacBio Illumina platforms. Small parameters observed, including increased protein treatment one sites. We observed increasing yields crops site. Soil fungal showed differences driven by site, AM fungi site-year combination. Network analysis revealed several network modules correlated increases POXC respiration. This research uniquely addresses interactions between no-till production Ohio.

Pseudomonas sp. G31 and Azotobacter sp. PBC2 Changed Structure of Bacterial Community and Modestly Promoted Growth of Oilseed Rape

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(23), P. 13168 - 13168

Published: Dec. 7, 2024

Oilseed rape is one of the most important oilseed crops, requiring high levels nitrogen fertilization. Excessive use, however, leads to numerous negative environmental impacts, spurring search for sustainable, environmentally friendly alternatives reduce reliance on mineral fertilizers. One promising approach involves plant-growth-promoting bacteria (PGPB), which can support growth and lessen need traditional This study evaluates a selected microbial consortium comprising bacterial isolates obtained from soil:
