Download or read book Ceratocystis and Ophiostoma written by Michael J. Wingfield and published by . This book was released on 1993 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book is based on a symposium held in Bad Windsheim, Germany, in Aug. 1990. The 30 chapters are grouped into 5 sections. Part I concerns morphological taxonomy of the ophiostomatoid fungi, including their anamorphs. In Part II, nonmorphological taxonomic approaches are considered, including genetic, biochemical, developmental and molecular characters. In Part III, the pathological aspects are introduced, beginning with considerations of saprobic growth and progressing through tree diseases to human diseases. Part IV includes reviews of a variety of insect vector systems and host responses to both the insects and the fungi. A few chapters, including information on methods for handling ophiostomatoid fungi, a key for their identification and a list of described species, were not presented at the symposium."--pub. desc.
Book Synopsis Ceratocystis and Ophiostoma Species Infecting Wounds on Hardwood Trees, with Particular Reference to South Africa by : Gilbert Kamgan Nkuekam
Download or read book Ceratocystis and Ophiostoma Species Infecting Wounds on Hardwood Trees, with Particular Reference to South Africa written by Gilbert Kamgan Nkuekam and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis concerns the study of selected Ceratocystis species and Ophiostoma species infecting wounds on broad-leaved trees, particularly those occurring in Africa. However, two chapters also deal with these fungi from Australia, Norway, Sweden and Austria. The dissertation is comprised of a literature review, followed by four research chapters, addressing the occurrence of Ceratocystis spp. and Ophiostoma spp. in Africa, Australia and Norway. The first chapter of the dissertation is a review of Ceratocystis spp. and Ophiostoma spp. with particular reference to Africa, hardwood tree species and wound infections. The review highlights the importance of wood and trees, especially on the African continent, and discusses the threat of deforestation. This is despite efforts by many African countries to establish forests of non-native tree species to address the demand for wood and wood products on the continent. Reforestation is associated with increased risks of the introduction of pests and pathogens, including species of Ceratocystis and Ophiostoma. The taxonomic history of these two fungal genera is summarized, and the review further focuses on the economically important species in these genera, particularly those infecting hardwood tree species on the African continent. The lack of information regarding Ceratocystis spp. and Ophiostoma spp. on hardwood trees in Africa is thus highlighted. Furthermore, the review summarised the dispersal mechanisms of these pathogens, highlighting dispersal too and infection of wounds. Ceratocystis pirilliformis was described in 2003 and it is the only species in the Ceratocystis fimbriata species complex that has pear-shaped ascomatal bases. This fungus was first described from Australia where Eucalyptus spp. are endemic. It was later reported from South Africa on Eucalyptus grandis trees. Chapter two of this dissertation attempts to address questions regarding the geographic distribution, impact and origin of C. pirilliformis in South Africa. This was in line with the fact that it has been suggested that the fungus is likely native to Australia. To address this question, surveys were conducted in many Eucalyptus planting areas in South Africa and the genetic diversity of the fungus in the country was investigated using microsatellite markers previously developed for C. fimbriata. C. pirilliformis was found in three Eucalyptus-growing areas of South Africa, which has considerably increased the known geographic range of the fungus in South Africa. The gene diversity as well as the genotypic diversity for the fungus was found to be very low in the country and the population is apparently clonal. Results thus support the view that C. pirilliformis was accidentally introduced into South Africa. In chapter three of this dissertation, O. quercus is reported for the first time from wounds on non-native Acacia mearnsii in Uganda. In addition a new Pesotum sp., P. australi prov. nom. is described from wounds on native A. mearnsii in Australia. This fungus resembles other Pesotum anamorphs of Ophiostoma in many ways, especially species of the O. piceae complex. However, it can be distinguished from these species by many morphological traits and also based on phylogenetic inference. The closest phylogenetic neighbor of P. australi prov. nom. is O. quercus. The fact that it was isolated from A. mearnsii in Australia indicates that it is probably a native fungus in that area. In chapter four, two Ceratocystis spp. and one Ophiostoma sp. are described as new to science, from wounds on native broad-leaved tree in South Africa. Three other Ophiostomaspp. are also reported in this study. Until recently, very little research has been done with regard to Ceratocystis spp. and Ophiostoma spp. occurring on native tree species in Africa. However, results presented in this chapter strongly suggest that these fungi are common on native trees in Africa and many other species, including potential pathogens await discovery. Chapter five of the dissertation reports, for the first time, Ophiostoma catonianum, O. pluriannulatum and O. quercus from native broad-leaved trees in Norway. It also reports O. catonianum for the first time from Austria and O. quercus for the first time from Sweden. In the past, very little research has been undertaken to explore the diversity of these fungi on hardwood trees in the Nordic countries or other parts of Europe, where most research has been focused on Ceratocystis spp. and Ophiostoma spp. associated with conifer-infesting bark beetles. This chapter represents a preliminary study with important discoveries. It indicates that these fungi are common on wounds on hardwood trees in Europe and emphasizes the importance of expanding these studies in the Nordic countries, to include more hosts and geographic areas. Such studies will almost certainly reveal more species and possibly new species of Ceratocystis and Ophiostoma.

Download or read book The Elms written by C.P. Dunn and published by Springer Science & Business Media. This book was released on 2000-01-31 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elms occur, both naturally and cultivated, throughout much of the temperate world. Because of their high tolerance to extreme growing conditions and their widespread distribution, elms have been widely planted in cities, towns and rural areas throughout North America and northern Europe. As such, their current demise due to several pandemics of Dutch elm disease has spurred a huge body of research on breeding for disease resistance, conservation and systematics. The Elms: Breeding, Conservation and Disease Management provides the current state of knowledge in these areas and is an important reference work for pathologists, breeders, taxonomists, and arborists.

Download or read book Cacao Diseases written by Bryan A. Bailey and published by Springer. This book was released on 2016-02-22 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the current state of knowledge concerning cacao pathogens and methods for their management. Topics discussed include the history, biology and genetic diversity of Moniliophthora species (which cause witches’ broom and frosty pod rot) and Phytophthora species (which cause black pod rot) that cause diseases resulting in major losses to cacao production. Emerging pathogens such as Cacao swollen shoot virus and Ceratobasidium theobromae (which causes vascular streak dieback) are also discussed in detail, along with many pathogens of significant local concern. Most of these pathogens represent major risks to global cacao production should they expand into new areas, breaking out of their current limited distributions. By considering cacao diseases as a group, similarities in the available tools and techniques used in their management become apparent, as do their limitations. Gaps in our current knowledge of cacao pathogens and the management of the diseases they cause are detailed, and suggestions for future research directions are provided. This insight allows readers to consider cacao disease threats from a more comprehensive, global perspective and paves the way for an improved synergy of efforts between the various research programs, agencies, and industries, both private and public, with vested interests in cacao production, and cacao farmers.
