Development of new molecular markers for phylogeny and molecular identification of arbuscular mycorrhizal fungi (Glomeromycota)
Because of the high genetic variability of the nuclear-encoded ribosomal RNA genes within single spores of arbuscular mycorrhizal fungi (AMF, Glomeromycota), new alternative marker genes are needed to better resolve closely related taxa. Based on published nucleotide sequences of the mitochondrial large ribosomal subunit (mt-LSU), new fungal-specific primers were constructed and successfully us...
متن کاملBiodiversity of arbuscular mycorrhizal fungi in agroecosystems
Arbuscular mycorrhizal fungi [AMF] are soil fungi which form a mutualistic symbiosis with the roots of plants. A variety of benefits to the host have been ascribed to mycorrhizae, most often enhanced uptake of immobile nutrients from the soil, notably P. An understanding of the impacts of agronomic practices upon communities of these fungi would help to ensure an opportunity for the utilization...
متن کاملDNA barcoding of arbuscular mycorrhizal fungi.
SUMMARY *Currently, no official DNA barcode region is defined for the Fungi. The COX1 gene DNA barcode is difficult to apply. The internal transcribed spacer (ITS) region has been suggested as a primary barcode candidate, but for arbuscular mycorrhizal fungi (AMF; Glomeromycota) the region is exceptionably variable and does not resolve closely related species. *DNA barcoding analyses were perfo...
متن کاملAncestral lineages of arbuscular mycorrhizal fungi (Glomales).
Using new and existing 18S rRNA sequence data, we show that at least five species of glomalean fungi lie outside the previously defined families and diverged very early in the evolution of that group. These five fungi would have been missed by many previous ecological studies because their sequences are not well matched to available taxon-specific primers and they do not stain well with the sta...
متن کاملMeiotic genes in the arbuscular mycorrhizal fungi
The arbuscular mycorrhizal fungi (AMF) are important symbionts of land plants, which are known for their tremendous positive effects on terrestrial ecosystems, their peculiar cellular features, and their very old evolutionary history. To date, no sexual stage or apparatus have ever been observed in these organisms; a remarkable absence for a eukaryotic lineage. For this reason, AMF have long be...
