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.

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.

Control of Herbaspirillum seropedicae NifA Activity by Ammonium Ions and Oxygen [PDF]

Journal of Bacteriology, 1999
ABSTRACT 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 O 2 sensitivity or Fe dependence.

Bacterial fitness for plant colonization is influenced by plant growth substrate

New Phytologist, Volume 248, Issue 6, Page 3168-3190, December 2025.
Summary Despite advances in our understanding of bacterial plant colonization, the extent to which growth substrate influences the molecular mechanisms enabling bacteria to efficiently colonize plants remains poorly understood. To address this, we used randomly barcoded transposon mutagenesis sequencing (RB‐TnSeq) in Paraburkholderia graminis OAS925 ...

Differential Protein Expression Analysis of Sugarcane in Response to Multi‐Strain Plant Growth Promoting Bacterial Inoculants and Nutrition—Molybdenum

Food and Energy Security, Volume 14, Issue 6, November/December 2025.
ABSTRACT Plant growth‐promoting bacteria (PGPB) enhance crop yields by altering the physiological responses of plants. A deeper understanding of the molecular mechanisms involved in interactions among bacterial strains and nutrients may clarify the inconsistent effects of molybdenum (Mo) and the key regulators associated with multi‐trait PGPB on the ...

Inter‐domain cross‐talk controls the NifA protein activity of Herbaspirillum seropedicae [PDF]

FEBS Letters, 2001
Herbaspirillum seropedicae is an endophytic diazotroph, which colonizes sugar cane, wheat, rice and maize. The activity of NifA, a transcriptional activator of nif genes in H. seropedicae, is controlled by ammonium ions through a mechanism involving its N‐terminal domain.

PlantRNA_sniffer : a SVM-based workflow to predict long intergenic non-coding RNAs in plants [PDF]

, 2017
Non-coding RNAs (ncRNAs) constitute an important set of transcripts produced in the cells of organisms. Among them, there is a large amount of a particular class of long ncRNAs that are difficult to predict, the so-called long intergenic ncRNAs ...
