“…Las esporas se fijaron permanentemente en una solución de PVLG (glicoglicerina de alcohol polivenilico). Con 400 x aumento en el microscopio de trasmision de luz se observaron las esporas y se clasificaron morfologicamente a nivel de género y especie, siguiendo la clasificación propuesta por Oehl et al (2011).…”

El presente estudio tuvo como objetivo conocer la abundancia y diversidad de Hongos de Micorriza Arbuscular (HMA) asociados con cacao Theobroma cacao L. en tres diferentes agroecosistemas (AGR), ubicados en el distrito de Irazola, provincia de Padre Abad, región Ucayali, en la Amazonía peruana. Los AGR incluyeron: 1) Cacao en monocultivo (AGR-1), 2) Cacao asociado con Inga edulis – guaba (AGR-2), y 3) cacao con cobertura de kudzu (Pueraria phaseoloides) (AGR-3). Se realizaron cuatro evaluaciones del número de esporas de HMA durante el período de julio a octubre del 2013. La abundancia fue mayor en el AGR-3, con 1 100 a 780 esporas por 100 gr de suelo, seguido por los AGR-2 y AGR-1; sin embargo, se encontró mayor diversidad en el AGR-2 identificándose 29 especies, seguido por los AGR-1 y AGR-3. Las especies de HMA identificadas pertenecían a los géneros Acaulospora, Ambispora, Archeospora, Cetraspora, Clareideoglomus, Diversispora, Fuscutata, Glomus, Kuklospora, Pacispora, Paraglomus y Sclerocystis. Se concluye que el número de esporas esta relacionado con la densidad de la cobertura, mientras la diversidad de especies HMA parece estar asociada con la diversidad de especies de plantas, siempre ycuando ninguna especie vegetal domine la cobertura.

“…and the Glomeromycotina (Schüßler and Walker 2010). In Glomus spp., all layers of the subtending hyphal wall and the spore wall form concurrently and the subtending hyphal wall layer continuous with the structural laminate spore wall layer arises far below the spore base and, thereby, the subtending hypha is persistent and its wall is colored similarly to the laminate spore wall layer (Oehl et al 2011b;Błaszkowski 2012). In contrast, the subtending hyphal wall of all Diversispora spp., also those with dark-colored spores, is hyaline to pale-colored and continuous only with a spore wall layer or layers overlying the main structural laminate spore wall layer, or the components of the subtending hyphal wall are continuous with all these spore wall layers (Oehl et al 2011b).…”

However, the laminate spore wall layer probably arises de novo sequentially after the full differentiation of the spore wall layer(s), which cover them, and starts developing either at the level of the lower surface of the spore wall layer directly adhering to its upper surface or slightly below the spore base (Oehl et al 2011b).…”

A new genus, Desertispora, and a new species, Diversispora sabulosa, in the family Diversisporaceae (order Diversisporales, subphylum Glomeromycotina)

Phylogenetic analyses of sequences of the SSU-ITS-LSU nrDNA segment and the RPB1 gene showed that the arbuscular mycorrhizal fungus originally described as Diversispora omaniana does not belong to the genus Diversispora, but represents a separate clade at the rank of genus in the family Diversisporaceae of the order Diversisporales. The closest natural relatives of the fungus proved to be species of the genera Corymbiglomus and Redeckera. Consequently, the new genus was named Desertispora, and Di. omaniana was renamed De. omaniana comb. nov. In addition, the morphological and histochemical features of spores and mycorrhizal structures of a new Diversispora sp., Di. sabulosa, were described and the closest relatives of the species were determined based on phylogenetic analyses of sequences of the two loci mentioned above. The new fungus was grown in single-species cultures established from spores extracted from a trap culture inoculated with a mixture of the rhizosphere soil and root fragments of Ammophila arenaria that had colonized maritime sand dunes of the Curonian Spit located in the north of Lithuania. Diversispora sabulosa was never found before in many different sites of the world which were sampled during the last 34 years by the last author of the paper. Also, the lack of molecular sequences in public databases of identity ≥ 97% to sequences of Di. sabulosa suggests that the fungus is rare on the Earth.

“…However, S. viscosum spores are hyaline to pale straw (http://invam.caf.wvu.edu/). Redecker et al (2013) concluded that the morphological features used to erect Septoglomus (Oehl et al 2011) are symplesiomorphies that can not define monophyletic groups.…”

Septoglomus jasnowskae and Septoglomus turnauae, two new species of arbuscular mycorrhizal fungi (Glomeromycota)

et al. 2014

Phylogenetic analyses of SSU-ITS-LSU nrDNA sequences and morphological studies of spores and mycorrhizae confirmed our supposition of finding two new species of arbuscular mycorrhizal fungi of the genus Septoglomus in the phylum Glomeromycota. Morphologically, the first species, named S. jasnowskae, is distinguished by its pale yellow to brownish yellow, small spores with a 2-layered spore wall, of which the colourless outer layer 1 stains dark in Melzer's reagent and layer 2 is laminate. The spores usually arise in loose clusters. The structures most distinguishing S. turnauae are its two coloured laminate layers in the 4-layered spore wall. In the field S. jasnowskae was associated with roots of Ammophila arenaria and an unrecognized plant species colonizing maritime dunes of the Mediterranean Sea near Thessalonica (Greece) and Calella (Spain), respectively, and S. turnauae formed mycorrhiza with a Cistus sp. (Cistaceae) growing in the soil of a mine located in Sulcis-Iglesiente, SW-Sardinia, Italy. In single-species cultures with Plantago lanceolata as host plant, the mycorrhiza of S. jasnowskae consisted of arbuscules, hyphae and vesicles, and that of S. turnauae comprised arbuscules and hyphae only.
