Download or read book Advances in Molecular Systematics of Clavicipitaceous Fungi Sordariomycetes written by Ryan M. Kepler and published by . This book was released on 2010 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historical concepts of Clavicipitaceae have included a broad range of species that display diverse morphologies, ecological modes and host associations. When subjected to multigene phylogenetic investigation of evolutionary history, the family was found to be polyphyletic, largely driven by diversity in the genus Cordyceps, previously containing over 400 taxa. The majority of Cordyceps sensu lato now resides in the families Cordycipitaceae, for which the genus Cordyceps has been retained owing to the placement of the type C. militaris, and the genera Ophiocordyceps and Elaphocordyceps in Ophiocordycipitaceae. The genus Metacordyceps was defined for species of Cordyceps remaining in Clavicipitaceae sensu stricto and contains relatively few species owing to convergent morphologies. Clavicipitaceae remains considerably diverse and its members attack hosts across three kingdoms of life, including insects and rotifers, plants and other fungi. There remains a significant number of Cordyceps species for which molecular or morphological data are insufficient, and are therefore considered incertae sedis with regards to family until new material is available for examination. This work expands the sampling of taxa in Clavicipitaceae sensu lato for inclusion in phylogenetic reconstruction, with particular emphasis on residual species of Cordyceps. The resulting phylogenies were then used to refine concepts morphological features that define boundaries between taxa and explore the evolution of host association, morphology and ecology with ancestral character-state reconstruction. Taxon sampling was increased by extensive field collections and collaborations with other researchers. The diversity present in newly acquired specimens represents all three pathogen groups. The inclusion of these taxa in a five-gene dataset (nrSSU, nrLSU, TEF, RPB1, RPB2) advances understanding of systematic relationships within Clavicipitaceae. Molecular data supports the movement of seven species from Cordyceps sensu lato to Metacordyceps, doubling the number of species known for the genus. The addition of new species reveals significant structure within the genus and allows for a reevaluation and strengthening of morphological concepts attributed to the genus. A clade of species sister to Clavicipitaceae was identified as Veterocordyceps gen. nov. This finding provides clarity to the results of previous workers who considered species in the genus as members of Ophiocordyceps based on morphological data and a more limited molecular dataset. Cordyceps fratricida, a pathogen of ergot, and the rice pathogen Ustilaginoidea virens were placed phylogenetically within Clavicipitaceae. The genus Tyrranocordyceps gen. nov. was established for fungal pathogens that attack closely related species of ergot. Tyrranocordyceps represents a sexual state for a clade of fungal pathogens known only from asexual states. Ustilaginoidea virens was found to occupy a separate lineage of plant pathogens, representing a third clade of clavicipitaceous fungi deriving their nutrition from a plant source. Ancestral character-state reconstruction reveals plant pathogens/endophytes have arisen multiple times during the history of the family and T. fratricida evolved from a plant pathogenic ancestor. The switch to a plant based nutritional mode appears to be facilitated by an ancestral host association with scale insects (Hemiptera: Sternorrhycha:Coccoidea). These insects are sessile in their adult stage and insert their mouthparts directly into living plant tissues, a characteristic that might mediate the acquisition of plant nutrients by their fungal pathogens and eventually result in bypassing the insect host all together. Finally, ancestral character-state reconstructions were performed on a phylogeny representing teleomorphic taxa from throughout Hypocreales for the characters of stipe (absence or presence) and habitat (terrestrial or arboreal). Hypocreales was found to have evolved from a terrestrial, astipitate ancestor. Stipitate morphologies were derived multiple times over the evolution of the order. This observation accounts for the phylogenetic signal in the stipe characters of color and texture. The characters of stipe and habitat were found to be highly correlated. Species occurring in arboreal habitats tend to be astipitate. This was inferred to be the retention of the ancestral state for early diverging members of Cordycipitaceae. However, all other astipitate, arboreal species were inferred to have lost the stipe after moving from a terrestrial habitat. This is likely an evolutionary response to release from evolutionary pressures to elevate reproductive tissues above a substrate.
Download or read book Biology of Microfungi written by De-Wei Li and published by Springer. This book was released on 2016-03-18 with total page 651 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference book includes 24 chapters written by a group of experts in the different fields of microfungi and cover a broad range of topics on microfungi. It provides the most updated information on the latest development in systematics and taxonomy of microfungi, new techniques which were developed in the last ten years and their application in microfungal research. After the International Code of Nomenclature for algae, fungi, and plants (Melbourne Code) was adopted by the Eighteenth International Botanical Congress Melbourne, Australia, July 2011, it has had a profound impact on mycology and its research. Fungal nomenclature changes and its significance to fungal taxonomy and naming of microfungi in the future is discussed in detail. Since dual names system for fungi developing both sexual and asexual states, and fungi developing only asexual state is no longer available, the first five chapters will clarify some confusion and provides perspective views on the direction for future research. The next nine chapters cover microfungi and their ecological roles or functions in the different habitats (air, indoor, aquatic, marine, plants, soils, etc). The remaining 13 chapters cover the relationship of microfungi and humans (good and bad) and usage or application microfungi in different industries, such as food, agriculture, forestry, green technology, pharmaceutics, and medicine, as well as in our daily life. The book bridges the gap between basic mycological research and applied mycology and provide readers a unique set of information and knowledge of microfungi generated from multiple angles in different fields of mycology.

Download or read book Ecophysiology of Spiders written by Wolfgang Nentwig and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently another book on insect physiology was published. It was restricted to a few focal points as are many of these new insect physiology books, but there was considerable depth in its specialized point of view. We were dis cussing the structure of this book and of insect physiology books, in general, when Prof. Remmert asked me " . . . and what about books on spider physio logy?" Silence. Then I started to explain "oh yes, there is a congress pro ceedings volume on this topic and there is a group with excellent publica tions on another topic . . . ", but I felt that this answer was weak. One can no longer buy the proceedings volume in a bookshop and to read a series of publications on a given topic one must search in a library for a dozen journals. Why is there not a single book on spider physiology comparable with the many books on insect physiology? Are spiders a scientific ivory tower, far from public interest and commercial importance? I do not think so, although spiders are one of the many "forgotten" animal groups which always grew in the shadow of the insects. There are research groups working on spider physiology, there are fascinating phenomena in this animal group and there are plenty of exciting results. Spiders may have been always underresearch ed, but research is progressing. In the last few years, new books have been published, e. g.
Download or read book The Ecology of Fungal Entomopathogens written by Helen E. Roy and published by Springer Science & Business Media. This book was released on 2010-02-04 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of the ecology of fungal entomopathogens has vastly increased since the early 1800’s, but remains challenging. The often complex interactions between pathogen and host are being unravelled through eloquent research and the importance of the often subtle interactions, in determining the success or failure of biological control, cannot be underplayed. The realm of ecology is vast and deciphering insect-fungal pathogen interactions within an ecological context will take us on voyages beyond our imagination. This book brings together the work of renowned scientists to provide a synthesis of recent research on the ecology of fungal entomopathogens exploring host-pathogen dynamics from the context of biological control and beyond. Dr. Helen Roy leads zoological research in the Biological Records Centre at the NERC Centre for Ecology & Hydrology, UK. The focus of her research is insect community interactions with particular emphasis on the effects of environmental change. She has been working on the ecological interactions between fungal entomopathogens and their hosts for 15 years; this continues to be a source of fascination. She has been an associate editor of BioControl since 2006. Dr. Dave Chandler is an insect pathologist at the University of Warwick, UK. He has studied entomopathogenic fungi for just over 20 years. He has particular interests in entomopathogenic fungi as biocontrol agents of horticultural crops, fungal physiology and ecology, and the pathogens of honeybees. Dr. Mark Goettel is an insect pathologist at the Lethbridge Research Centre of Agriculture & Agri-Food Canada, specializing in the development of fungal entomopathogens as microbial control agents of insects. In addition to this research, he has been extensively involved in the review and revision of the regulations for registration of microbial control agents and has addressed regulatory and safety issues at the international level. He is currently President of the Society for Invertebrate Pathology and has been Editor-in-Chief of Biocontrol Science & Technology since 2000. Dr. Judith K. Pell heads the Insect Pathology Group in the Department for Plant and Invertebrate Ecology at Rothamsted Research, UK. She leads research on the ecology of fungal entomopathogens, to elucidate their role in population regulation and community structure and to inform biological control strategies. Specifically: intraguild interactions; the relationships between guild diversity, habitat diversity and ecosystem function; pathogen-induced host behavioural change. Dr. Eric Wajnberg is a population biologist specialising in behavioural ecology, statistical modelling and population genetics. He is also an expert in biological control, with more than 20 years experience of working with insect parasitoids. He has been the Editor in Chief of BioControl since 2006. Dr. Fernando E. Vega is an entomologist with the United States Department of Agriculture, Agricultural Research Service, in Beltsville, Maryland, USA. He conducts research on biological methods to control the coffee berry borer, the most important insect pest of coffee throughout the world.

Download or read book The Insect Ovary written by Jürgen Büning and published by Springer Science & Business Media. This book was released on 1994-07-31 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will give an overview of insect ovaries, showing the diversities and the common traits in egg growth processes. The idea to write this book developed while looking at the flood of information which appeared in the early 1980s on early pattern formation in Drosophila embryos. At this time a significant breakthrough was made in studies of this little fly, combining molecular biological methods with classical and molecular genetics. The answers to questions about early pattern formation raised new questions about the architecture of ovaries and the growth of eggs within these ovaries. However, by concentrating only on Drosophila it is not possible to form an adequate picture of what is going on in insect ovaries, since the enormous diversity found among insects is not considered sufficiently. Almost forgotten, but the first to study the architecture of ovaries, was Alexander Brandt writing in 1878 in aber das Ei und seine Bildungsstaette (On the egg and its organ of development). More than 100 years later, a series of ten books or more would be required to survey all the serious informa tion we have today on insect oogenesis. Thus, this book is a personal selection and personal view on the theme, and the authors must be excused by all those scientists whose papers could not be included. The book briefly describes the ectodemes, i. e.
