Book excerpt: Excerpt from A Preliminary Report of a Nematode Observed on Citrus Roots and Its Possible Relation With the Mottled Appearance of Citrus Trees Mr. J. R. Hodges, Horticultural Inspector, of Covina, California, has found nematodes in'the soil scraped from the roots of trees with badly mottled leaves. He examined some of the diseased trees in his district and came to the conclusion that the nematodes injured the roots and were the cause of the disease. Twice previously nematodes have been reported in connection with citrus trees. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Citrus production is one of the world's largest agricultural industries. Surveys of the occurrence of nematodes attacking citrus show they are present in all citrus-growing countries of the world. The first report of and association between a nematode and citrus appeared in 1889 (673), but it was not until the discovery in 1912 of Tylenchulus semipenetrans Cobb, 1913, on the roots of citrus trees in California (965) that a nematode was found to cause a diseased condition of citrus later called slow decline.

Download or read book The Family Trichodoridae Stubby Root and Virus Vector Nematodes written by Wilfrida Decraemer and published by Springer Science & Business Media. This book was released on 1995-11-30 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The family Trichodoridae was established by Thorne in 1935 but it remained of limited taxonomie interest until 1951 when Christie and Perry associated Trichodorus christie (now Paratrichodorus minor) with a "stubby root disease" that affected certain crops in Florida, USA and interest further increased from 1960 when P. pachydermus was implicated as a vector of the economically important tobacco raule virus. Such discoveries gave an impetus to studies on many aspects of the biology of trichodorid nematodes with a consequent proliferation of new species described from different parts of the world. The number of species increased from twelve in 1957 to a present day total exceeding eighty. This rapid expansion in the number of species was accompanied by several reappraisals of the taxonomy and systematies of the family, the most notable changes being the creation of the genus Paratrichodorus by Siddiqi in 1974 and the recognition of the monodelphic genera Monotrichodorus and Allotrichodorus respectively by Andrassy in 1976 and Rodriguez-M, Sher and Siddiqi in 1978. Reliable and unambiguous identification of taxa is dependent on the known reliability of a range of characters, whieh remains of paramount importance in taxonomy even when biochemical and molecular methodology is available. In this book each of the species, including synonyms and species inquirenda, that comprise the family Trichodoridae is re-described from meticulous mieroscopie examination of type specimens, material from official nematode collections and populations in the field.

Download or read book The Craft and Science of Coffee written by Britta Folmer and published by Academic Press. This book was released on 2016-12-16 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Craft and Science of Coffee follows the coffee plant from its origins in East Africa to its current role as a global product that influences millions of lives though sustainable development, economics, and consumer desire. For most, coffee is a beloved beverage. However, for some it is also an object of scientifically study, and for others it is approached as a craft, both building on skills and experience. By combining the research and insights of the scientific community and expertise of the crafts people, this unique book brings readers into a sustained and inclusive conversation, one where academic and industrial thought leaders, coffee farmers, and baristas are quoted, each informing and enriching each other. This unusual approach guides the reader on a journey from coffee farmer to roaster, market analyst to barista, in a style that is both rigorous and experience based, universally relevant and personally engaging. From on-farming processes to consumer benefits, the reader is given a deeper appreciation and understanding of coffee's complexity and is invited to form their own educated opinions on the ever changing situation, including potential routes to further shape the coffee future in a responsible manner. Presents a novel synthesis of coffee research and real-world experience that aids understanding, appreciation, and potential action Includes contributions from a multitude of experts who address complex subjects with a conversational approach Provides expert discourse on the coffee calue chain, from agricultural and production practices, sustainability, post-harvest processing, and quality aspects to the economic analysis of the consumer value proposition Engages with the key challenges of future coffee production and potential solutions

Download or read book Agrobacterium From Biology to Biotechnology written by Tzvi Tzfira and published by Springer Science & Business Media. This book was released on 2007-12-25 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agrobacterium is a plant pathogen which causes the “crown-gall” disease, a neoplastic growth that results from the transfer of a well-defined DNA segment (“transferred DNA”, or “T-DNA”) from the bacterial Ti (tumor-inducing) plasmid to the host cell, its integration into the host genome, and the expression of oncogenes contained on the T-DNA. The molecular machinery, needed for T-DNA generation and transport into the host cell and encoded by a series of chromosomal (chv) and Ti-plasmid virulence (vir) genes, has been the subject of numerous studies over the past several decades. Today, Agrobacterium is the tool of choice for plant genetic engineering with an ever expanding host range that includes many commercially important crops, flowers, and tree species. Furthermore, its recent application for the genetic transformation of non-plant species, from yeast to cultivated mushrooms and even to human cells, promises this bacterium a unique place in the future of biotechnological applications. The book is a comprehensive volume describing Agrobacterium's biology, interactions with host species, and uses for genetic engineering.

Download or read book Nematode Vectors of Plant Viruses written by Charles E. Taylor and published by . This book was released on 1997 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viruses transmitted by nematodes are responsible for many economically important diseases of crops. Thus, when in the late 1950s, this mode of disease propagation was demonstrated by proof of the transmission of grapevine fanleaf disease by Xiphinema index, it marked the start of a significant and fruitful period of research. Since that time, however, numerous reviews have been published on different aspects of nematode transmission of plant viruses and the nematode transmitted viruses themselves. However, until now there has been a lack of any source which draws all of this research together. This book fills this need by providing a valuable overview of the last forty years of research into the transmission of viruses by nematodes, as well as setting the agenda for future investigations. This book is an important resource for all crop protectionists, nematologists, and plant virologists.
