Microorganisms 2021 Apr 27;9(5). Epub 2021 Apr 27.

Laboratorio de Microbiología Molecular y Biotecnología Ambiental, Departamento de Química & Centro de Biotecnología Daniel Alkalay-Lowitt, Universidad Técnica Federico Santa María, Avenida España 1680, Valparaíso 2390123, Chile.

Sulfate reducing prokaryotes (SRP) are a phylogenetically and physiologically diverse group of microorganisms that use sulfate as an electron acceptor. SRP have long been recognized as key players of the carbon and sulfur cycles, and more recently, they have been identified to play a relevant role as part of syntrophic and symbiotic relations and the human microbiome. Despite their environmental relevance, there is a poor understanding about the prevalence of prophages and CRISPR arrays and how their distribution and dynamic affect the ecological role of SRP.

New lineages of photobionts in Bolivian lichens expand our knowledge on habitat preferences and distribution of Asterochloris algae.

Sci Rep 2021 Apr 22;11(1):8701. Epub 2021 Apr 22.

Department of Plant Taxonomy and Nature Conservation, Faculty of Biology, University of Gdańsk, Wita Stwosza 59, 80308, Gdańsk, Poland.

We studied the biodiversity of Asterochloris photobionts found in Bolivian lichens to better understand their global spatial distribution and adaptation strategies in the context of a worldwide phylogeny of the genus. Based on nuclear ITS rDNA, the chloroplast rbcL gene and the actin type I gene we reconstructed a phylogenetic tree that recovered nine new Asterochloris lineages, while 32 Bolivian photobiont samples were assigned to 12 previously recognized Asterochloris lineages. We also show that some previously discovered Asterochloris photobiont species and lineages may occur in a broader spectrum of climatic conditions, and mycobiont species and photobionts may show different preferences along an altitude gradient.

First mitogenome of subfamily Langiinae (Lepidoptera: Sphingidae) with its phylogenetic implications.

Gene 2021 Apr 18;789:145667. Epub 2021 Apr 18.

Collaborative Innovation Center of Recovery and Reconstruction of Degraded Ecosystem in Wanjiang Basin Co-founded by Anhui Province and Ministry of Education, School of Ecology and Environment, Anhui Normal University, Wuhu, Anhui 241000, China. Electronic address:

To date, a relatively complete classification of Sphingidae (Lepidoptera) has been generated, but the phylogeny of the family remains need to be fully resolved. Some phylogenetic relationships within Sphingidae still remains uncertain, especially the taxonomic status of the subfamily Langiinae and its sole included genus and species, Langia zenzeroides. To begin to address this problem, we generated nine new complete mitochondrial genomes, including that of Langia, and together with that of Theretra oldenlandiae from our previous study and 25 other Sphingidae mitogenomes downloaded from GenBank, analyzed the phylogenetic relationships of Sphingidae and investigated the mitogenomic differences among members of the Langiinae, Sphinginae, Smerinthinae and Macroglossinae.

Electronic address:

Analysis of ancient environmental DNA (eDNA) has revolutionized our ability to describe biological communities in space and time, by allowing for parallel sequencing of DNA from all trophic levels. However, because environmental samples contain sparse and fragmented data from multiple individuals, and often contain closely related species, the field of ancient eDNA has so far been limited to organellar genomes in its contribution to population and phylogenetic studies. This is in contrast to data from fossils where full-genome studies are routine, despite these being rare and their destruction for sequencing undesirable. Read More
