Lipopolysaccharides in diazotrophic bacteria [PDF]

Frontiers in Cellular and Infection Microbiology, 2014
Biological nitrogen fixation is a process in which the atmospheric nitrogen (N2) is transformed into ammonia (NH3) by a select group of nitrogen-fixing organisms, or diazotrophic bacteria.

Diazotrophic Bacteria and Their Mechanisms to Interact and Benefit Cereals

Molecular Plant-Microbe Interactions, 2021
Plant-growth-promoting bacteria (PGPB) stimulate plant growth through diverse mechanisms. In addition to biological nitrogen fixation, diazotrophic PGPB can improve nutrient uptake efficiency from the soil, produce and release phytohormones to the host ...

Diazotrophic Bacterial Community of Degraded Pastures [PDF]

Applied and Environmental Soil Science, 2017
Pasture degradation can cause changes in diazotrophic bacterial communities. Thus, this study aimed to evaluate the culturable and total diazotrophic bacterial community, associated with regions of the rhizosphere and roots of Brachiaria decumbens Stapf.

A Phosphorylation-Dependent Partner-Switching-Like Module Regulates a Glycosyltransferase Required for Heterocyst Polysaccharide Layer Formation in Anabaena sp. Strain PCC 7120. [PDF]

Mol Microbiol
The glycosyltransferase All4160 is regulated by the reversible phosphorylation of Ser74. The kinase Alr3423 phosphorylates and inactivates All4160, while the SpoIIE‐like phosphatase HenR restores its activity through dephosphorylation. A nonphosphorylatable variant of All4160 bypasses the need for HenR, which demonstrates that a phosphorylation ...

Characterization of diazotrophic root endophytes in Chinese silvergrass (Miscanthus sinensis)

Microbiome, 2022
Background Phytoremediation is a potentially cost-effective way to remediate highly contaminated mine tailing sites. However, nutrient limitations, especially the deficiency of nitrogen (N), can hinder the growth of plants and impair the phytoremediation

A Simple in situ Assay to Assess Plant-Associative Bacterial Nitrogenase Activity

Frontiers in Microbiology, 2021
Assessment of plant-associative bacterial nitrogen (N) fixation is crucial for selection and development of elite diazotrophic inoculants that could be used to supply cereal crops with nitrogen in a sustainable manner.

COMBINATION OF Azospirillum brasilense AND Bradyrhizobium japonicum IN THE PROMOTION OF INITIAL CORN GROWTH

Revista de Agricultura Neotropical, 2021
Biological formulations used as inoculants are increasingly present in grasses, especially in corn. Positive results in promoting plant growth, with different associations with diazotrophic bacteria, show these capacities of interaction to act as plant ...

Microbial quality of soil from the Pampa biome in response to different grazing pressures

Genetics and Molecular Biology, 2015
The aim of this study was to evaluate the impact of different grazing pressures on the activity and diversity of soil bacteria. We performed a long-term experiment in Eldorado do Sul, southern Brazil, that assessed three levels of grazing pressure: high ...

Comparison of the Total, Diazotrophic and Ammonia-Oxidizing Bacterial Communities Between Under Organic and Conventional Greenhouse Farming

Frontiers in Microbiology, 2020
Organic greenhouse farming is an innovative system that may maintain a high yield and healthy agroecosystem. There have been no rigorous studies on the comparison of total and nitrogen-cycling bacterial community in vegetable soils between organic and ...

EFFECTS OF SELECTED DIAZOTROPHS ON MAIZE GROWTH

Frontiers in Plant Science, 2016
Laboratory, greenhouse, and field experiments were conducted at the University of KwaZulu-Natal, Pietermaritzburg, South Africa in the 2010 2011 and 2011 2012 seasons to study the effects of eight strains of diazotrophic bacteria on the growth and yield ...
