Acaulospora aspera, a new fungal species in the Glomeromycetes from rhizosphere soils of the inka nut (Plukenetia volubilis L.) in Peru by Corazon Guivin, Mike Anderson, Cerna Mendoza, Agustín, Guerrero Abad, Juan Carlos, Vallejos Tapullima, Adela, Carballar Hernández, Santos, Alves da Silva, Gladstone, Oehl, Fritz

“…The surface of the structural spore wall layer is crowded with small depressions, 0.4-0.7 μm in diameter, up to 0.8 μm deep, and only 1.1-1.8 apart, giving the spore surface a rough, washboardlike appearance, especially when the outermost, evanescent wall layer has disappeared. Phylogenetically, the new species is close to A. spinosissima, A. excavata and to other morphologically more similar species such as A. spinosa and A. tuberculata, which form spiny or tuberculate projections on the outermost, semi-persistent spore wall layer, or A. herrerae, A. kentinensis, A. scrobiculata and A. minuta, which on the structural spore wall layer all have more pronunced pits than A. aspera. …”

Molecular characterization of a phytoplasma of the ash yellows group occurring in strawberry (Fragaria x ananassa Duch.) plants in Argentina by Fernandez, Franco Daniel, Conci, Vilma Cecilia, Kirschbaum, Daniel Santiago, Conci, Luis Rogelio

“…The putative RFLP profile was indistinguishable from the Argentinean alfalfa witches’ broom (ArAWB) phytoplasma. The phylogenetic analysis of nearly full-length 16S rDNA sequence and 16S-23S spacer region yielded a consensus tree wherein ASP clustered into the ash yellows group (16Sr VII) with high confidence values (95), generating a separated branch (100 bootstrap value) together with ArAWB (16Sr VII-C). …”

“…Although all tested DNA samples from the collected ticks resulted negative to the detection of Piroplasmida and Rickettsia spp., 16 samples (16.5%, including all hosts) were positive in the 16S rDNA gene PCR that detects bacteria from the Anaplasmataceae family. Phylogenetic analysis of seven obtained partial sequences resulted in the identification of three bacteria: two Ehrlichia spp. …”
