Capsular and extracellular polysaccharides of the diazotrophic rhizobacterium Herbaspirillum seropedicae Z78

Microbiology, 2012
The diazotrophic endophyte Herbaspirillum seropedicae Z78 was shown to possess a capsule containing two high-molecular-weight glycolipids, one of which was of a lipopolysaccharide nature. These glycolipids differed considerably in the fatty acid composition of their lipid components.

Identification of NH+4-regulated genes of Herbaspirillum seropedicae by random insertional mutagenesis

Archives of Microbiology, 2007
Random mutagenesis using transposons with promoterless reporter genes has been widely used to examine differential gene expression patterns in bacteria. Using this approach, we have identified 26 genes of the endophytic nitrogen-fixing bacterium Herbaspirillum seropedicae regulated in response to ammonium content in the growth medium.

Regulation of nif genes expression in Azospirillum brasilense and Herbaspirillum seropedicae

1989
Several ethylenediamine (EDA)-resistant mutants of A. brasilense were isolated and found to depress nitrogenase in the presence of high NH 4 + concentrations. These mutants were defective in NH 4 + uptake and capable of excreting NH4 + in N-free semi-solid medium. A gene library of H. seropedicae strain HZ78 was constructed in cosmid pVK102.

Role of Herbaspirillum seropedicae Nifa Domains on the Expression of nif Genes

2000
H. seropedicae NifA is a transcriptional activator protein of nif genes. This protein comprises three domains: the C-terminal domain contains a helix-turn-helix motif that is responsible for binding to specific activator-binding sites (UAS) of nif gene promoters.
