Disease relevance of Herbaspirillum

• The dominant cultures acquired from the CAS groundwater were from the Herbaspirillum/Oxalobacter clade [1].
• 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 [2].
• A 4-chlorophenol-degrading bacterial strain, formerly designated as a strain of Comamonas testosteroni, was reclassified as a member of the genus Herbaspirillum based on its phenotypic and chemotaxonomic characteristics, as well as phylogenetic analysis using 16S rDNA sequences [3].
• The deduced amino acid sequence derived from the sequence of a fragment of DNA from the free-living diazotroph Herbaspirillum seropedicae was aligned to the homologous protein sequences encoded by the nifA genes from Azorhizobium caulinodans, Rhizobium leguminosarum, Rhizobium meliloti and Klebsiella pneumoniae [4].

High impact information on Herbaspirillum

• The activity of a truncated form of Herbaspirillum seropedicae NifA in different genetic backgrounds showed that its regulatory domain is involved in nitrogen control but not in O2 sensitivity or Fe dependence [5].
• Both diazotrophic Herbaspirillum species could be differentiated with meso-erythritol and N-acetylglucosamine [6].
• L-arabinose metabolism in Herbaspirillum seropedicae [7].
• Ammonium inhibition of nitrogenase activity in Herbaspirillum seropedicae [2].
• The pathway for L-arabinose metabolism in Herbaspirillum seropedicae was shown to involve nonphosphorylated intermediates and to produce alpha-ketoglutarate [7].

Chemical compound and disease context of Herbaspirillum

• Herbaspirillum chlorophenolicum sp. nov., a 4-chlorophenol-degrading bacterium [3].
• On the basis of utilization of adipate (-), N-acetyl-D-glucosamine (+), meso-erythritol (-), L-rhamnose (-) and meso-inositol (-) Herbaspirillum frisingense sp. nov. can be distinguished from other known Herbaspirillum spp [8].
• Herbaspirillum seropedicae strains mutated in the nifX or orf1 genes showed 90% or 50% reduction in nitrogenase activity under low levels of iron or molybdenum respectively [9].
• Significance of Herbaspirillum seropedicae inoculation and/or straw amendment on growth and dinitrogen fixation of wheat using 15N-dilution method [10].
• Tetrachlorophenol degradation by the Herbaspirillum sp. K1 was enhanced by yeast extract, malate, glutamate, pyruvate, peptone and casitone [11].

Gene context of Herbaspirillum

• Cloning of a recA-like gene from the diazotroph Herbaspirillum seropedicae strain Z78 [12].
• Sequence and structural organization of a nif A-like gene and part of a nifB-like gene of Herbaspirillum seropedicae strain Z78 [4].
• The transcriptional activator NtrC controls the expression and activity of glutamine synthetase in Herbaspirillum seropedicae [13].
• Adsorption of Protein GlnB of Herbaspirillum seropedicae on Si(111) Investigated by AFM and XPS [14].
