Symbiotic efficiency of Rhizobium leguminosarum sv. trifolii strains originating from the subpolar and temperate climate regions

open access: yesScientific Reports
Red clover (Trifolium pratense L.) is a forage legume cultivated worldwide. This plant is capable of establishing a nitrogen-fixing symbiosis with Rhizobium leguminosarum symbiovar trifolii strains.

Presentation_1_Evaluation of Primers Targeting the Diazotroph Functional Gene and Development of NifMAP – A Bioinformatics Pipeline for Analyzing nifH Amplicon Data.PDF

open access: yes, 2018
Diazotrophic microorganisms introduce biologically available nitrogen (N) to the global N cycle through the activity of the nitrogenase enzyme. The genetically conserved dinitrogenase reductase (nifH) gene is phylogenetically distributed across four ...

Nucleotide sequence of the nifH gene coding for nitrogen reductase in the acetic acid bacterium Acetobacter diazotrophicus

open access: yes, 1998
The nifH gene sequence of the nitrogen-fixing bacterium Acetobacter diazotrophicus was determined with the use of the polymerase chain reaction and universal degenerate oligonucleotide primers. The gene shows highest pair-wise similarity to the nifH gene

Non-cyanobacterial nifH phylotypes in the North Pacific Subtropical Gyre detected by flow-cytometry cell sorting

open access: yes, 2013
In contrast to cyanobacteria, the significance of bacteria and archaea in oceanic N2 fixation remains unknown, apart from the knowledge that their nitrogenase (nifH) genes are diverse, present in all oceans and at least occasionally expressed.

Plant growth-promoting genes from metagenomic DNA of rice rhizosphere show marked diversity

open access: yesDiscover Plants
This study assessed the distribution and diversity of important plant growth-promoting genes from the metagenomic DNA of rice rhizosphere soil. The multiplex polymerase chain reaction (mPCR) was employed for the simultaneous amplification of three genes ...

Global biogeography of N2-fixing microbes: nifH amplicon database and analytics workflow

open access: yes
This figshare entry has the nifH ASV database described in Morando, Magasin et al. 2024 (in review). In this work we compiled published data for marine nitrogenase (nifH) amplicons that were sequenced on Illumina platforms and ran the datasets through ...

PHÂN LẬP VÀ NHẬN DIỆN MỘT SỐ CHỦNG VI KHUẨN CỐ ĐỊNH NITƠ TRÊN CÂY BẮP

open access: yesTạp chí Khoa học Đại học Cần Thơ, 2010
Từ các bộ phận của cây bắp (rễ, thân, lá), chúng tôi đã phân lập được 78 chủng vi khuẩn có khả năng cố định nitơ từ N2 của không khí. Các chủng vi khuẩn phân lập được có các đặc tính giống như mô tả của các tác giả trước đây.
