Evidence for two possible glnB-type genes in Herbaspirillum seropedicae [PDF]

Journal of Bacteriology, 1997
Two glnB-like genes have been isolated from Herbaspirillum seropedicae by complementation of the Klebsiella pneumoniae glnB502 mutant for growth on nitrate. One of these glnB-like genes has been sequenced and shows strong identity with GlnB proteins derived from other organisms. A Tn5-20 mutation of this glnB was Nif negative.

Endophytic Herbaspirillum seropedicae expresses nif genes in gramineous plants [PDF]

FEMS Microbiology Ecology, 2003
Abstract The interactions between maize, sorghum, wheat and rice plants and Herbaspirillum seropedicae were examined microscopically following inoculation with the H. seropedicae LR15 strain, a Nif(+) (Pnif::gusA) mutant obtained by the insertion of a gusA-kanamycin cassette into the nifH gene of the H. seropedicae wild-type strain.

The genome of the endophytic bacterium H. frisingense GSF30T identifies diverse strategies in the Herbaspirillum genus to interact with plants

Frontiers in Microbiology, 2013
The diazotrophic, bacterial endophyte Herbaspirillum frisingense GSF30T has been identified in biomass grasses grown in temperate climate, including the highly nitrogen-efficient grass Miscanthus.

Comparative molecular analysis of Herbaspirillum strains by RAPD, RFLP, and 16S rDNA sequencing

Genetics and Molecular Biology, 2003
Herbaspirillum spp. are endophytic diazotrophic bacteria associated with important agricultural crops. In this work, we analyzed six strains of H. seropedicae (Z78, M2, ZA69, ZA95, Z152, and Z67) and one strain of H.

A transthyretin-related protein is functionally expressed in Herbaspirillum seropedicae

Biochemical and Biophysical Research Communications, 2009
Transthyretin-related proteins (TRPs) constitute a family of proteins structurally related to transthyretin (TTR) and are found in a large range of bacterial, fungal, plant, invertebrate, and vertebrate species. However, it was recently recognized that both prokaryotic and eukaryotic members of this family are not functionally related to transthyretins.

An unusual case of Herbaspirillum huttiense bacteraemia in a haemodialysis patient. [PDF]

Nephrology (Carlton)
Abstract Herbaspirillum spp. is a common environmental bacterium usually found in soil, plant roots, and water. It is rarely associated with infection in immunocompromised patients, and rarely reported infections in immunocompetent patients. We report the first case of a Herbaspirillum huttiense bacteraemia in a non‐neutropenic home haemodialysis ...

Isolation and Characterization of Herbaspirillum seropedicae Z78 Lipopolysaccharide

Izvestiya of Saratov University. Chemistry. Biology. Ecology, 2011
Lipopolysaccharide (LPS) preperations were isolated from the outer membrane of the bacterium Herbaspirillum seropedicae Z78 by using various methods. SDS electrophoresis revealed that the samples were heterogeneous in nature and that R-form molecules were predominant.
