Genome analysis of the necrotrophic fungal pathogens Sclerotinia sclerotiorum and Botrytis cinerea

Sclerotinia sclerotiorum and Botrytis cinerea are closely related necrotrophic plant pathogenic fungi notable for their wide host ranges and environmental persistence. These attributes have made these species models for understanding the complexity of necrotrophic, broad host-range pathogenicity. Despite their similarities, the two species differ in mating behaviour and the ability to produce asexual spores. We have sequenced the genomes of one strain of S. sclerotiorum and two strains of B. cinerea. The comparative analysis of these genomes relative to one another and to other sequenced fungal genomes is provided here. Their 38–39 Mb genomes include 11,860–14,270 predicted genes, which share 83% amino acid identity on average between the two species. We have mapped the S. sclerotiorum assembly to 16 chromosomes and found large-scale co-linearity with the B. cinerea genomes. Seven percent of the S. sclerotiorum genome comprises transposable elements compared t

Historical ‘signposts’ and other temporal indicators in the Czech lexicon

This article posits that the Czechs employ a great many historical markers, previously applied to other events of national importance, which help to shape collective memory and right the ‘wrongs’ of the past. It is argued that these temporal indicators share a number of clearly defined characteristics, and that their use is too systematic and calculated to be merely a function of the constraints of the lexicon. The first part of the study considers in detail questions of semantics (especially the distinction between denotation and connotation), the lexicographical sources available to the researcher, and the lexical ‘signpost’ in context, while the second part focuses on practical examples of lexical re-appropriation since 1918, with particular reference to dictionaries and the Czech National Corpus.University of Wolverhampto

We have mapped the S. sclerotiorum assembly to 16 chromosomes and found large-scale co-linearity with the B. cinerea genomes. Seven percent of the S. sclerotiorum genome comprises transposable elements compared to <1% of B. cinerea. The arsenal of genes associated with necrotrophic processes is similar between the species, including genes involved in plant cell wall degradation and oxalic acid production. Analysis of secondary metabolism gene clusters revealed an expansion in number and diversity of B. cinerea–specific secondary metabolites relative to S. sclerotiorum. The potential diversity in secondary metabolism might be involved in adaptation to specific ecological niches. Comparative genome analysis revealed the basis of differing sexual mating compatibility systems between S. sclerotiorum and B. cinerea. The organization of the mating-type loci differs, and their structures provide evidence for the evolution of heterothallism from homothallism. These data shed light on the evolutionary and mechanistic bases of the genetically complex traits of necrotrophic pathogenicity and sexual mating. This resource should facilitate the functional studies designed to better understand what makes these fungi such successful and persistent pathogens of agronomic crops

Impact of advanced autonomous non-medical practitioners in emergency care: protocol for a scoping study.

INTRODUCTION Emergency care services are looking for new models of care delivery to deal with changing patient demographics and increased pressures. It has been suggested that advanced non-medical practitioners might be valuable for delivering such new models of care. However, it is not clear what the impact of the deployment of advanced non-medical practitioners in emergency care is. This scoping study addresses the following research question: What is known from the literature about the different types of impact of the deployment of advanced (autonomous) non-medical practitioners in emergency care? METHODS AND ANALYSIS A scoping study will be undertaken to examine and map the impact of the deployment of advanced non-medical practitioners in emergency care. The scoping study follows the methodology proposed by Arksey and O'Malley. Searches will be carried out on databases of peer-reviewed literature and other sources to systematically identify and characterise the literature. Papers will be screened using a 2-stage process to identify the most relevant literature. Papers will be screened by title and abstract, followed by full-text review. Data abstraction and synthesis will be performed using a narrative thematic analysis. ETHICS AND DISSEMINATION We will communicate the findings to Health Education England, NHS Improvement and the Royal College of Emergency Medicine through existing links provided by members of the project team. We anticipate that the findings will also be of interest to other similar organisations internationally. By identifying gaps in the research literature, we anticipate that the study will generate recommendations for informing future high-quality research studies about the impact of advanced non-medical practitioners in emergency care as well as in other settings. The research findings will be submitted for publication to relevant peer-reviewed journals as well as professional magazines. The scoping study uses only previously published material, and does not require ethical review
