Consortium of Phosphorus-Solubilizing Bacteria Promotes Maize Growth and Changes the Microbial Community Composition of Rhizosphere Soil

Agronomy, Journal Year: 2024, Volume and Issue: 14(7), P. 1535 - 1535

Phosphorus deficiency severely limits crop yields and hinders sustainable agricultural development. Phosphate-solubilizing bacteria (PSB) are beneficial for growth because they enhance the uptake utilization of phosphorus. This study explored phosphorus-solubilizing, IAA-producing, nitrogen-fixing, potassium-solubilizing, siderophore-producing abilities three bacterial strains (Pantoea sp. J-1, Burkholderia cepacia Z-7, Acinetobacter baumannii B-6) screened from maize rhizosphere. A pot experiment was also conducted to explore role PSB in maize. Finally, effects on physicochemical properties, enzyme activities, microbial community structure rhizosphere soil were analyzed. The results showed that strain Z-7 had strongest phosphorus solubilization, nitrogen fixation, potassium siderophore production, while J-1 exhibited highest yield IAA. application promoted plants different extents. Among treatments, mixed treatment (J-1 + most potent promotion effect, consortium significantly enhanced activity phosphatase. Soil pH, total (TP), (TK), available (AP), NH4+-N, NO3−-N key factors plants. In addition, altered soil, relative abundance Proteobacteria increased by 16.07–69.10% compared control. These have obvious growth-promoting abilities, with potential productivity as excellent candidate development biological fertilizers.

A joint role of iron oxide and temperature for methane production and methanogenic community in paddy soils

Geoderma, Journal Year: 2023, Volume and Issue: 433, P. 116462 - 116462

Published: April 3, 2023

Microbial methanogenesis in paddy soils contributes approximately one-fifth of global anthropogenic methane (CH4) release, creating severe negative climate feedback. The dynamics iron oxides flooded fields, as well temperature changes, have an impact on CH4 production. However, the relationship between two, their interactive mechanisms influencing production and microbial communities soils, is not yet clear. Therefore, we investigated effects (15, 25 35 °C) oxide (ferrihydrite) methanogenic community structure two Chinese one subtropical temperate. We characterized shifts using high-throughput sequencing bacteria, archaea mcrA genes following anaerobic incubation for 90 days. Our results showed that significantly promoted Fe reduction both together regulated by reducing number methanogens. Additionally, sensitivity was higher temperate than soil. also demonstrated ferrihydrite can inhibit relative abundance Methanosarcinales altering patterns methanogens these soils. Likewise, increases changes Methanobacteriales, promoting methanogenesis. Overall, our provide new insights into role regulating greenhouse gas emissions from

A low-methane rice with high-yield potential realized via optimized carbon partitioning

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 920, P. 170980 - 170980

Published: Feb. 17, 2024

Global rice cultivation significantly contributes to anthropogenic methane emissions. The emissions are caused by methane-producing microorganisms (methanogenic archaea) that favoured the anoxic conditions of paddy soils and small carbon molecules released from roots. However, different cultivars associated with differences in emission rates suggesting there is a considerable natural variation this trait. Starting hypothesis sugar allocation within plant an important factor influencing both yields emissions, aim study was produce high-yielding lines low In study, offspring (here termed progeny lines) crosses between newly characterized low-methane variety, Heijing 5, three elite varieties, Xiushui, Huayu Jiahua, were selected for combined high-yield properties. Analyses total organic carbohydrates showed stored more above-ground tissues than maternal varieties. Also, metabolomic analysis rhizospheric soil surrounding reduced levels glucose other carbohydrates. allocation, roots shoots, further supported transcriptome using massively parallel sequencing mRNAs demonstrated elevated expression transporters SUT-C SWEET as compared parental Furthermore, measurement plants, grown greenhouse well outdoor paddies, reduction approximately 70 % Taken together, we report here on independent low-methane-emission high yield potential.
