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...
Two new ectocarpic arbuscular mycorrhizal fungal species, Glomus drummondii and G. walkeri (Glomeromycota), found in maritime sand dunes of northern Poland and those adjacent to the Mediterranean Sea are described and illustrated. Mature spores of G. drummondii are pastel yellow to maize yellow, globose to subglobose, (58-)71(-85) micromdiam, or ovoid, 50-80x63-98 microm. Their wall consists of...
The mutualistic symbiosis involving Glomeromycota, a distinctive phylum of early diverging Fungi, is widely hypothesized to have promoted the evolution of land plants during the middle Paleozoic. These arbuscular mycorrhizal fungi (AMF) perform vital functions in the phosphorus cycle that are fundamental to sustainable crop plant productivity. The unusual biological features of AMF have long fa...
Abstract. Soil fungi play important roles in the functioning of ecosystems, but they are challenging to measure. Using a continental-scale dataset, we developed and evaluated new method estimate relative abundance dominant phyla diversity Australian soil. The relies on development spectrotransfer functions with state-of-the-art machine learning uses publicly available data soil environmental pr...
Soils sequester and release substantial atmospheric carbon, but the contribution of fungal communities to soil carbon balance under rising CO2 is not well understood. Soil properties likely mediate these fungal responses but are rarely explored in CO2 experiments. We studied soil fungal communities in a grassland ecosystem exposed to a preindustrial-to-future CO2 gradient (250 to 500 ppm) in a ...
Heritable endobacteria, which are transmitted from one host generation to the next, are subjected to evolutionary forces that are different from those experienced by free-living bacteria. In particular, they suffer consequences of Muller's ratchet, a mechanism that leads to extinction of small asexual populations due to fixation of slightly deleterious mutations combined with the random loss of...
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...
