Download or read book Diseases and Pathogens of Eucalypts written by PJ Keane and published by CSIRO PUBLISHING. This book was released on 2000-10-25 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last fifty years, there has been an increasing recognition that eucalypts are vulnerable to a wide range of diseases. They have suffered destructive epidemics, particularly of dieback caused by the cinnamon fungus in native forests, of foliar diseases and cankers in plantations, and of dieback of remnant trees on agricultural and grazing land. This has stimulated intensive research into the causes and management of diseases of the eucalypts. This work represents a comprehensive review of our current knowledge of the health and diseases of eucalypts.

Download or read book Plant and Insect Mycoplasma Techniques written by M. J. Daniels and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Only 14 years have passed since the first publication appeared which implicated mycoplasmas as agents of plant disease. The diseases them selves have been known for much longer; indeed clover phyllody, a typical example, was described in the seventeenth century, well before any animal mycoplasma diseases had been documented. The early history of plant mycoplasmas is described in Chapter 2 and one obvious conclusion to be drawn from the frustrating experiences of the earlier workers is that the experimental methods at their disposal were simply inadequate for the task. Progress in science depends critically upon the development of new methods. Although important advances have been made in plant and insect mycoplasmology, notably in the discovery of spiroplasmas, many intractable problems remain. Most plant myco plasmas cannot yet be cultured in vitro, and their natural plant habitat, the phloem, is one of the most difficult plant tissues for the experi menter to handle, placing severe restrictions on the type of experiments which can be performed in vivo. It is clear that radically new methods may be required to solve these problems. A survey of the progress which has been made shows that application of techniques from a wide range of disciplines has been necessary. A successful individual or group of workers must possess the skills of a plant pathologist, a plantsman, a plant physiologist, a light-and electron microscopist, a bacteriologist, a biochemist, an immunologist, an ento mologist, a virologist and a molecular geneticist.
Download or read book Phytophthora Infestations in Forest Ecosystems written by Bruno Scanu and published by MDPI. This book was released on 2021-06-02 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oomycete genus Phytophthora represents one of the most notorious groups of tree pathogens in natural and semi-natural forest ecosystems. Since the discovery in the 1960s of the invasive P. cinnamomi, threatening some of the world’s richest plant communities in Australia, numerous Phytophthora diseases have been reported on forest trees worldwide, which were previously unknown to science. The most notable examples include the oak and beech declines triggered by different Phytophthora spp. in Europe and North America, the findings of sudden oak death and sudden larch death caused by P. ramorum in the Western USA and the U.K., respectively, and the association of P. austrocedri with mal del ciprés in Argentina and juniper decline in the U.K. All these epidemic events are driven by exotic invasive Phytophthora species, introduced through infested nursery plants from their native overseas environments. In recent years, many independent surveys have studied the diversity of Phytophthora species and the diseases they are causing across a diverse range of forests and other natural ecosystems. This Special Issue presents papers on Phytophthora surveys performed in different biogeographic regions and addresses the pathways, and ecological and economic impacts of these invasive forest pathogens.

Download or read book Pythium written by Mahendra Rai and published by CRC Press. This book was released on 2020-01-28 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pythium is one of the most important phytopathogens causing significant damage to agriculture, forest, and nurseries, etc. It is an unseen enemy of the root zone of various plants and hence considered as "hidden terror" for a number of plants. An accurate diagnosis and identification of Pythium causing various infections in plants is very important because it is often confused with several other fungi. Pythium infections are difficult to control once they have set in. Therefore, its effective and ecofriendly management is of paramount importance. In addition, there are many reports on Pythium causing infections in human beings and animals. The present book on Pythium focuses on various aspects which mainly include pathogenesis, technological developments in detection and diagnosis, and its management. Key Features Includes identification of Pythium spp. by traditional and molecular methods Deals with different diseases caused by Pythium spp Describes the role of Pythium in mammalian diseases Incorporates various management strategies Discusses emerging role of nanotechnological tools for the management of Pythium diseases

Available in PDF, EPUB and Kindle. Book excerpt: Diversity, Distribution, and Current Status is the first volume in a three-volume series dedicated to the analysis of this important group of plant pathogens across Asia with a particular focus on geographic distribution. This book offers updated data on the most prevalent phytoplasma diseases specific to each region. Phytoplasmas are emerging plant pathogens all around the world, causing significant economic losses to crops, as well as affecting international trade. The chapters in Volume 1 look closely at different countries and regions across Asia, providing data on country-wide distribution, phytoplasma groups, insect vectors and transmission. The Phytoplama Diseases in Asian Countries series will be an essential read for university students, researchers and agriculturalists interested in Plant Pathology. Volume 1 will be of particular interest to those needing the latest data on the distribution and transmission rates specific to the various regions of Asia. - Reviews the geographical distribution of different phytoplasma diseases across Asia - Organized by country, providing an in-depth analysis of the phytoplasma prevalent in different regions - Provides a wealth of data associated with each phytoplasma disease - Highlights the insect vectors transmitting the bacteria

This book was released on 2015-06-26 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The broad host range pathogenic bacterium Agrobacterium tumefaciens has been widely studied as a model system to understand horizontal gene flow, secretion of effector proteins into host cells, and plant-pathogen interactions. Agrobacterium-mediated plant transformation also is the major method for generating transgenic plants for research and biotechnology purposes. Agrobacterium species have the natural ability to conduct interkingdom genetic transfer from bacteria to eukaryotes, including most plant species, yeast, fungi, and even animal cells. In nature, A. tumefaciens causes crown gall disease resulting from expression in plants of auxin and cytokinin biosynthesis genes encoded by the transferred (T-) DNA. Gene transfer from A. tumefaciens to host cells requires virulence (vir) genes that reside on the resident tumor-inducing (Ti) plasmid. In addition to T-DNA, several Virulence (Vir) effector proteins are also translocated to host cells through a bacterial type IV secretion system. These proteins aid in T-DNA trafficking through the host cell cytoplasm, nuclear targeting, and T-DNA integration. Genes within native T-DNAs can be replaced by any gene of interest, making Agrobacterium species important tools for plant research and genetic engineering. In this research topic, we provided updated information on several important areas of Agrobacterium biology and its use for biotechnology purposes.
