Assessing the quality of comparative genomics data and results with the cogeqc R/Bioconductor package

Methods in Ecology and Evolution, Volume 14, Issue 12, Page 2942-2952, December 2023., 2023
Abstract Comparative genomics has become an indispensable part of modern biology due to the advancements in high‐throughput sequencing technologies and the accumulation of genomic data in public databases. However, the quality of genomic data and the choice of parameters used in software tools used for comparative genomics can greatly impact the ...

Rhizopine biosensors for plant‐dependent control of bacterial gene expression

Environmental Microbiology, Volume 25, Issue 2, Page 383-396, February 2023., 2023
Abstract Engineering signalling between plants and microbes could be exploited to establish host‐specificity between plant‐growth‐promoting bacteria and target crops in the environment. We previously engineered rhizopine‐signalling circuitry facilitating exclusive signalling between rhizopine‐producing (RhiP) plants and model bacterial strains.

Revealing oxidative pentose metabolism in new Pseudomonas putida isolates

Environmental Microbiology, Volume 25, Issue 2, Page 493-504, February 2023., 2023
Abstract The Pseudomonas putida group in the Gammaproteobacteria has been intensively studied for bioremediation and plant growth promotion. Members of this group have recently emerged as promising hosts to convert intermediates derived from plant biomass to biofuels and biochemicals. However, most strains of P.

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.

Doses de nitrogênio e inoculação de Herbaspirillum seropedicae na cultura do milho em condições de solo fértil

Acta Agronómica, 2016
A fixação biológica de nitrogênio (FBN) pode ser uma abordagem tecnológica útil para aumentar a produ-ção de Gramíneas visto que alguns microrganismos, dentre os quais o gênero Herbaspirillum apresentam potencial para a FBN e produção de substâncias ...

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.

Promoção de enraizamento de microtoletes de cana-de-açúcar pelo uso conjunto de substâncias húmicas e bactérias diazotróficas endofíticas Rooting of micro seed pieces by combined use of humic substances and endophytic diazotrophic bacteria in sugar cane

Revista Brasileira de Ciência do Solo, 2008
Além do fornecimento direto de nutrientes por meio da mineralização da matéria orgânica ou pela fixação biológica de N2, as substâncias húmicas e as bactérias diazotróficas endofíticas podem afetar diretamente o metabolismo vegetal, modificando o padrão ...
