Abstract Peltigera globulata Miadl. & Magain, a new species in the P. ponojensis/monticola complex of section , is formally described. This clade was previously given interim designation sp. 17. It found sun-exposed and xeric habitats at high altitudes Peru Ecuador. can be easily recognized by its irregularly globulated margins covered mostly thick, white pruina, somewhat resembling soredia...

Although horizontal gene transfer is well documented in microbial genomes, no case has been reported in higher plants. We discovered horizontal transfer of the mitochondrial nad1 intron 2 and adjacent exons b and c from an asterid to Gnetum (Gnetales, gymnosperms). Gnetum has two copies of intron 2, a group II intron, that differ in their exons, nucleotide composition, domain lengths, and struc...

The yeast Candida glabrata is an opportunistic human fungal pathogen whose incidence has increased in the last two decades. Despite its name, this yeast is only distantly related to the model fungal pathogen C. albicans, and more closely related to Saccharomyces cerevisiae and other yeasts that underwent an ancient whole-genome duplication. Understanding what specific traits make C. glabrata a ...

Yarrowia lipolytica is a genetically tractable yeast species that has become an attractive model for analyses of lipid metabolism, due to its oleaginous nature. We investigated the regulation and evolution of lipid metabolism in non-Saccharomycetaceae yeasts, by carrying out a comparative physiological analysis of eight species recently assigned to the Yarrowia clade: Candida alimentaria, Y. de...

BACKGROUND Phytoplankton cultures are widely used in aquaculture for a variety of applications, especially as feed for fish larvae. Phytoplankton cultures are usually grown in outdoor tanks using natural seawater and contain probiotic or potentially pathogenic bacteria. Some Roseobacter clade isolates suppress growth of the fish pathogen Vibrio anguillarum. However, most published information c...

SNMPs are membrane proteins observed to associate with chemosensory neurons in insects; in Drosophila melanogaster, SNMP1 has been shown to be essential for the detection of the pheromone cis-vaccenyl acetate (CVA). SNMPs are one of three insect gene clades related to the human fatty acid transporter CD36. We previously characterized the CD36 gene family in 4 insect Orders that effectively cove...

We hypothesized that species of the Candida glabrata clade and species with phenotypic traits that overlap those of C. glabrata would produce white colonies on CHROMagar Candida medium. Of 154 isolates (seven species) tested, C. bracarensis, C. nivariensis, C. norvegensis, C. glabrata, and C. inconspicua produced white colonies; the Pichia fermentans group and C. krusei did not. Many of these s...

Leishmaniasis is a debilitating infectious disease that has a variety of clinical forms. In China, visceral leishmaniasis (VL) is the most common symptom, and L. donovani and/or L. infantum are the likely pathogens. In this study, multilocus sequence typing (MLST) of five enzyme-coding genes (fh, g6pdh, icd, mpi, pgd) and two conserved genes (hsp70, lack) was used to investigate the phylogeneti...

BACKGROUND Resistance-associated variants have been related to treatment failure of hepatitis C virus (HCV) therapy with direct-acting antiviral drugs. The aim of our study was to analyze the prevalence of clinically relevant resistance-associated variants within NS3 in patients infected with HCV genotype 1a (GT1a) in Spain. METHODS We performed a cross-sectional study on 2568 patients from 1...
