Diazotrophic Diversity and Distribution in the Tropical and Subtropical Atlantic Ocean
The data suggest a community shift from filamentous cyanob bacteria in surface waters to unicellular cyanobacteria and/or heterotrophic bacteria in deeper waters. Expand
Genetic diversity of the arbuscular mycorrhizal fungus Glomus intraradices as determined by mitochondrial large subunit rRNA gene sequences is considerably higher than previously expected.
Glomus intraradices is a widespread arbuscular mycorrhizal fungus (AMF), which has been found in an extremely broad range of habitats, indicating a high tolerance for environmental factors and aExpand
Phylogeny of the glomeromycota (arbuscular mycorrhizal fungi): recent developments and new gene markers.
Nuclear-encoded rDNA and rpb1 protein gene sequences are used to reassess the phylogeny of the Glomeromycota and discuss possible implications. Expand
Mitochondrial large ribosomal subunit sequences are homogeneous within isolates of Glomus (arbuscular mycorrhizal fungi, Glomeromycota).
The findings indicate that the intra-individual sequence heterogeneity of the Glomeromycota may be a peculiar feature of the nuclear genes, and mtLSU and its introns have the potential to be highly sensitive genetic markers for these fungi in the future. Expand
A novel clade of sporocarp-forming species of glomeromycotan fungi in the Diversisporales lineage
Small subunit ribosomal rDNA and internal transcribed spacer data from specimens of glomeromycotan sporocarps from tropical areas that were assigned to three morphospecies are obtained to facilitate identification of these fungi using rDNA sequences within colonized roots or the environment. Expand
Root expression of nitrogen metabolism genes reflects soil nitrogen cycling in an organic agroecosystem
Root expression of genes such as GS1 could complement soil inorganic N pools and measurements of soil microbial activity to serve as integrative indicators of rapid plant-soil N cycling. Expand
Phylogeny of the Glomeromycota (arbuscular mycorrhizal fungi): recent developments and new gene markers
The fungal symbionts of arbuscular mycorrhiza form a monophyletic group in the true Fungi, the phylum Glomeromycota. Fewer than 200 described species currently are included in this group. The onlyExpand
Development of new molecular markers for phylogeny and molecular identification of arbuscular mycorrhizal fungi (Glomeromycota)
RPB1 sequences of representatives of the remaining families are needed for for a comprehensive phylogeny of glomeromycotan fungi, as all members of the Glomeromycota contained an intron at the same location in their RPB1 gene, which seems to be ideal for molecular species identification using restriction analysis in community studies of the AMF.
