Discovery of Backusella paraconstricta sp. nov. (Mucorales, Mucoromycota) in an upland forest in northeastern Brazil with an identification key for Backusella from the Americas
During a survey of mucoralean fungi in soil from an upland forest area located in Pernambuco, Brazil, a strain of Backusella (URM 8637) was isolated. Based on morphological, physiological, and molecular data [internal transcribed spacer (ITS) and large subunit (LSU) ribosomal DNA regions], it was recognized that this Backusella differed from all other species in the genus. Morphologically, the new species is characterized as forming varied-shaped columellae, including elongated, basally constricted, unisporate (rare) and multisporate sporangiola, and ellipsoidal sporangiospores. The maximum temperature growth of URM 8637 on malt extract agar and potato dextrose agar was 36 °C. In the phylogram, it was closely related to B. constricta. Based on the evidence from the analyzed datasets, a new species of Backusella is proposed. An updated identification key for Backusella from the Americas is provided.
期刊介绍：
Experimental, theoretical and applied papers on all aspects of plant (including algae) and fungi biology are welcome. The submitted manuscript or its essential content must not have been published previously or be under consideration for publication elsewhere. Contributions should be substantial, written in high-quality English and show general interest. We expect that the submitted manuscript presents a great novelty in Botany, and this should attract a wide audience. Considering this, case studies are only considered if the narrative and implications are provided to be of general interest. Thus, manuscripts that report aspects of local interest are discouraged unless the implications of the findings are wide-reaching. Manuscripts with agronomic subjects are expected to contain a substantial amount of basic plant biology. Please see below some details for specific area.
