“…Future studies should explore the structure–function correlation of AMF and their colonization or application of selection pressure by the host plant species. Such information could help to design the inoculums of AMF as per the host plant species which could help in improving crop yield and ensuring ecosystem sustainability ( Al-Khaliel, 2010a , Al-Yahya’ei et al, 2017 , Sene et al, 2012a , Sene et al, 2012b ). Sustainability of the desert ecosystem is necessary because the deserts are home to some economically viable plants.…”

New Glomeromycotan Taxa, Dominikia glomerocarpica sp. nov. and Epigeocarpum crypticum gen. nov. et sp. nov. From Brazil, and Silvaspora gen. nov. From New Caledonia

“…Currently, of the many markers that have been used in phylogenetic studies of the Glomeromycota (Błaszkowski et al, 2018a(Błaszkowski et al, ,b, 2019aJobim et al, 2019;Magurno et al, 2019), those comprising the partial small subunit (18S), internal transcribed spacer (ITS1-5.8S-ITS2 = ITS), and partial large subunit (28S) nuc rDNA segment (= 18S-ITS-28S), as well as the largest subunit of RNA polymerase II (rpb1) gene, have the highest resolution power and characterize the highest proportion of described species within the Glomeromycota (Krüger et al, 2012;Stockinger et al, 2014;Al-Yahya'ei et al, 2017). The first marker allowed to separate, for example, Rhizoglomus dunense from Rhizoglomus clarum, whose morphologies are almost identical, but sequence divergence is very high (13.3%;Al-Yahya'ei et al, 2017). The sequence resolution of the rpb1 gene is higher and indicating that R. irregulare likely contains at least one cryptic species (Stockinger et al, 2014) and strongly confirming the uniqueness of R. dunense with a dissimilarity of 8.1% from R. clarum.…”

“…Later, new species of Dominikia and Kamienskia were described, whose spores were either (i) similar in color and size (Dominikia lithuanica, Dominikia litorea, Kamienskia divaricata), (ii) darker-colored (Dominikia aurea, Dominikia bernensis, Dominikia compressa, Dominikia duoreactiva, Dominikia emiratia), (iii) larger (D. compressa, D. duoreactiva, D. emiratia), and (iv) formed mainly singly (Dominikia difficilevidera) (Oehl et al, 2014(Oehl et al, , 2015Błaszkowski et al, 2015bBłaszkowski et al, , 2016Błaszkowski et al, , 2018cAl-Yahya'ei et al, 2017) compared to the spores of the species listed above.…”
