Improved PCR primers for the detection and identification of arbuscular mycorrhizal fungi.
A set of PCR primers that should amplify all subgroups of arbuscular mycorrhizal fungi (AMF, Glomeromycota), but exclude sequences from other organisms, was designed to facilitate rapid detection andExpand

Phylogenies of atpD and recA support the small subunit rRNA-based classification of rhizobia.
The current classification of the rhizobia (root-nodule symbionts) assigns them to six genera. It is strongly influenced by the small subunit (16S, SSU) rRNA molecular phylogeny, but such single-geneExpand

The genome of Rhizobium leguminosarum has recognizable core and accessory components
BackgroundRhizobium leguminosarum is an α-proteobacterial N2-fixing symbiont of legumes that has been the subject of more than a thousand publications. Genes for the symbiotic interaction with plantsExpand

Introducing the bacterial 'chromid': not a chromosome, not a plasmid.
In addition to the main chromosome, approximately one in ten bacterial genomes have a 'second chromosome' or 'megaplasmid'. Here, we propose that these represent a single class of elements that haveExpand

The role of ecological theory in microbial ecology
Microbial ecology is currently undergoing a revolution, with repercussions spreading throughout microbiology, ecology and ecosystem science. The rapid accumulation of molecular data is uncoveringExpand

Legume-nodulating betaproteobacteria: diversity, host range, and future prospects.
Rhizobia form specialized nodules on the roots of legumes (family Fabaceae) and fix nitrogen in exchange for carbon from the host plant. Although the majority of legumes form symbioses with membersExpand

Burkholderia species are ancient symbionts of legumes.
Burkholderia has only recently been recognized as a potential nitrogen-fixing symbiont of legumes, but we find that the origins of symbiosis in Burkholderia are much deeper than previously suspected.Expand

Genome of an arbuscular mycorrhizal fungus provides insight into the oldest plant symbiosis
Significance The arbuscular mycorrhizal symbiosis between fungi of the Glomeromycota phylum and plants involves more than two-thirds of all known plant species, including important crop species. ThisExpand

Co‐existing grass species have distinctive arbuscular mycorrhizal communities
Arbuscular mycorrhizal (AM) fungi are biotrophic symbionts colonizing the majority of land plants, and are of major importance in plant nutrient supply. Their diversity is suggested to be anExpand

The transcriptome of the arbuscular mycorrhizal fungus Glomus intraradices (DAOM 197198) reveals functional tradeoffs in an obligate symbiont.
• The arbuscular mycorrhizal symbiosis is arguably the most ecologically important eukaryotic symbiosis, yet it is poorly understood at the molecular level. To provide novel insights into theExpand
