The Bacillus anthracis spore is the causative agent of the disease anthrax. The outermost structure of the B. anthracis spore, the exosporium, is a shell composed of approximately 20 proteins. The function of the exosporium remains poorly understood and is an area of active investigation. In this study, we analyzed the previously identified but uncharacterized exosporium protein ExsK. We found ...

Six lists of names from working groups set up under Art. 14.13 are approved, consisting of three names of families, 43 names of genera and five names of species, to be treated as conserved against the listed synonymous or homonymous names. Lists were compiled by working groups approved by the International Commission on the Taxonomy of Fungi and the Nomenclature Committee for Fungi: on Cordycep...

Cheirosporium gen. nov. is characterised by the production of sporodochial conidiomata, semi-macronematous to macronematous conidiophores that possess several distinct sterile branches, and cheiroid, smooth-walled conidia with rhexolytic secession. The 28S rDNA and ITS rDNA operon of this taxon were amplified and sequenced. A BLAST search revealed low homology between Cheirosporium triseriale a...

Abstract Our studies on lignicolous aquatic fungi in Thailand, Sweden, and the UK resulted collection of three new Halobyssothecium species ( H . bambusicola , phragmitis versicolor ) assigned to Lentitheciaceae (Pleosporales, Dothideomycetes). Multi-loci phylogenetic analyses combined large subunit, small internal transcribed spacers ribosomal DNA, translation elongation factor 1-alpha sequenc...

In members of the Bacillus cereus group the outermost layer of the spore is the exosporium, which interacts with hosts and the environment. Efforts have been made to identify proteins of the exosporium but only a few have so far been characterised and their role in determining spore architecture and spore function is still poorly understood. We have characterised the exosporium protein, YwdL. Δ...

Marine fungi represent a group of organisms extremely important from an ecological and biotechnological point of view, but often still neglected. In this work, an in-depth analysis on the systematic and the phylogenetic position of 21 sterile mycelia, isolated from Posidonia oceanica, was performed. The molecular (ITS and LSU sequences) analysis showed that several of them are putative new spec...
