Abstract:
... The lichenicolous ‘heterobasidiomycetes’ belong in the Tremellomycetes (Agaricomycotina) and in the Pucciniomycotina. In this paper, we provide an introduction and review of these lichenicolous taxa, focusing on recent studies and novelties of their classification, phylogeny and evolution. Lichen-inhabiting fungi in the Pucciniomycotina are represented by only a small number of species included in ...

Abstract:
... The advent of high throughput sequencing technologies provides an opportunity to resolve phylogenetic relationships among closely related species. By incorporating hundreds to thousands of unlinked loci and single nucleotide polymorphisms (SNPs), phylogenomic analyses have a far greater potential to resolve species boundaries than approaches that rely on only a few markers. Scleractinian taxa have ...

Abstract:
... The family Macrobiotidae is one of the most speciose and diverse groups among tardigrades. Although there have been attempts to reconstruct the phylogeny of this family, the evolutionary relationships within Macrobiotidae are only superficially determined as available genetic data cover only a small fraction of this vast group. Here, we present the first extensive molecular phylogeny of the family ...

A 49-year-old immunocompetent man sustained a splinter from his wooden deck, which resulted in a chronic cutaneous lesion. Originally identified as Scedosporium species on microscopic examination, genome sequenc ...

Diagnosis of Kinetoplastid infections in domestic animals is difficult, since parasitemia is intermittent and signs are nonspecific; it is mainly based on parasitological smears or concentration techniques, which lack sensitivity and depend on operator` expertise. Dogs are relev ...

Abstract:
... Effective quantification of Calonectria ilicicola in naturally infested soils is critical for evaluating and validating control measures for managing red crown rot disease in soybean. Counting of microsclerotia has been used to quantify this pathogen, but the method is laborious and time-consuming to process large numbers of soil samples using wet sieving. To overcome these issues, we developed an ...

Abstract:
... Physospermopsis (Apiaceae) comprises about 10 species, but its taxonomy and phylogeny are disputed. The genus is mostly distributed in the Himalayas and Hengduan Mountains at high elevation. Earlier molecular studies involving six species of Physospermopsis indicated that this genus is not monophyletic and is nested in the East Asia Clade. Therefore, the aims of this study were to re-assess the ph ...
