The RecX protein interacts with the RecA protein and modulates its activity in Herbaspirillum seropedicae [PDF]

Brazilian Journal of Medical and Biological Research, 2012
DNA repair is crucial to the survival of all organisms. The bacterial RecA protein is a central component in the SOS response and in recombinational and SOS DNA repairs.

Toxicity of herbicides used in the sugarcane crop to diazotrophic bacterium Herbaspirillum seropedicae [PDF]

Semina: Ciências Agrárias, 2014
The objective of this work was to identify herbicides used in the sugarcane crop that affects neither the growth, the development, of nor the process of biological nitrogen fixation (BNF) by the diazotrophic bacterium Herbaspirillum seropedicae. Eighteen

Identification and characterization of PhbF: A DNA binding protein with regulatory role in the PHB metabolism of Herbaspirillum seropedicae SmR1 [PDF]

BMC Microbiology, 2011
Background Herbaspirillum seropedicae SmR1 is a nitrogen fixing endophyte associated with important agricultural crops. It produces polyhydroxybutyrate (PHB) which is stored intracellularly as granules.

Evidence for the endophytic colonization of Phaseolus vulgaris(common bean) roots by the diazotroph Herbaspirillum seropedicae

Brazilian Journal of Medical and Biological Research, 2011
Herbaspirillum seropedicae is an endophytic diazotrophic bacterium, which associates with important agricultural plants. In the present study, we have investigated the attachment to and internal colonization of Phaseolus vulgaris roots by the H ...

DNA Methylation Shapes Seed-Borne Microbiome and Proteome Responses During Early Maize-Beneficial Bacteria Interactions. [PDF]

Plant Cell Environ
ABSTRACT Microorganism and plant interactions are crucial for development and environmental adaptation. Plant growth promoting bacteria enhance agricultural productivity in a sustainable manner, while epigenetic modifications such as DNA methylation regulate gene expression and adaptive responses.

L-arabinose metabolism in Herbaspirillum seropedicae [PDF]

Journal of Bacteriology, 1989
The pathway for L-arabinose metabolism in Herbaspirillum seropedicae was shown to involve nonphosphorylated intermediates and to produce alpha-ketoglutarate. The activities of the enzymes and the natures of several intermediates were determined.

Ammonium inhibition of nitrogenase activity in Herbaspirillum seropedicae [PDF]

Journal of Bacteriology, 1989
The effect of oxygen, ammonium ion, and amino acids on nitrogenase activity in the root-associated N2-fixing bacterium Herbaspirillum seropedicae was investigated in comparison with Azospirillum spp. and Rhodospirillum rubrum. H. seropedicae is microaerophilic, and its optimal dissolved oxygen level is from 0.04 to 0.2 kPa for dinitrogen fixation but ...
