Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Trichoderma species from China

浙江大学学报. 农业与生命科学版, 2004
Seventeen species of Trichoderma, isolated from soil or tree bark from China are identified based on morphological and physiological characters, and from their phylogenetic position inferred from parsimony analyses of nucleotide sequences of the internal

Phylogenetic position of Meteoromyrtus (Myrtaceae)

Telopea, 2016
We investigated the phylogenetic affinities of the rare and threatened Indian species Meteoromyrtus wynadensis (Bedd.) Gamble. Sequences from the ITS and ETS regions of nrDNA and the trnK/matK and psbA–trnH regions of the plastid genome were compiled in a 45 taxon dataset augmented by sequences from Genbank.

How phagocytic cells kill bacteria: Lessons from a professional killer

FEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

The complete mitochondrial genome of Electrona carlsbergi (Myctophiformes, Myctophidae) with phylogenetic consideration

Mitochondrial DNA. Part B. Resources, 2018
The complete mitochondrial genome of Electrona carlsbergi was obtained, which was 18,282 bp in size and including 13 protein-coding genes, 2 ribosomal RNAs, 23 transfer RNAs and 1 control region. The overall nucleotide composition is 27.92% for A, 24.66%

Phylogenetic position of Pseudohypocrea (Hypocreales)

Mycoscience, 2017
Abstract Based on morphological characteristics, a hypocrea-like collection from Hunan Province was found to be identical with Pseudohypocrea hongkongensis, which was originally reported only from Hong Kong, China. A living culture of the fungus was obtained from fresh ascomata, and its asexual morph is described for the first time.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Characterization of two complete chloroplast genomes of Lindera megaphylla (Lauraceae)

Mitochondrial DNA. Part B. Resources, 2019
Lindera megaphylla (Lauraceae) is an ecologically important and dominant evergreen broad-leaf tree species in the warm-temperate and subtropical zone of China. In this study, we sequenced and assembled two complete genomes of L. megaphylla (LM01 and LM02)

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...
