Ideally suited to horticulturalists and plant virologists, this highly useful text offers a multidisciplinary view on one of the major diseases of tomato crops, the tomato yellow leaf curl disease. It deals with epidemiological aspects of the disease as well as integrated pest management in the field. Coverage discusses the efforts aimed at breeding tomato plants resistant to the virus by classical breeding, by marker-assisted breeding and by genetic engineering.

Das Lehrbuch behandelt die PflanzenAkologie in folgenden Teilgebieten: Molekulare A-kophysiologie (Stressphysiologie) AutAkologie (WArme-, Wasser-, Kohlenstoff- und NAhrelementhaushalt der Gesamtpflanze) A-kosystemkunde (A-kosystemtheorie und die Pflanze als Teil von A-kosystemen) SynAkologie (Populationsbiologie der Pflanzen und VegetationsAkologie) Globale Aspekte der PflanzenAkologie (StoffkreislAufe, internationale Abkommen und sozioAkonomische Wechselwirkungen) Die A-kophysiologie untersucht Pflanzen am natA1/4rlichen Standort, bei denen mehr oder weniger starker Stress auf den Organismus einwirkt. In der molekularen A-kophysiologie wird der Einfluss von abiotischem und biotischem Stress zell- und molekularbiologisch bis hin zu den Genen verfolgt. SchAden und Anpassungen werden in der molekularen Dimension betrachtet. Hier beginnt das VerstAndnis fA1/4r die Vielfalt, mit der Pflanzen auf die Lebensbedingungen auf der Erde reagieren. In der AutAkologie kommen auf der Ebene der Einzelpflanze Struktur und Architektur als MAglichkeiten der Anpassung hinzu, auf der Ebene der A-kosysteme gewinnt auch die biologische und abiotische Umgebung zusAtzlichen Einfluss. Dies leitet A1/4ber zur Populationsbiologie und VegetationsAkologie, die die rAumliche Verteilung von Arten, die zeitliche Dynamik der AktivitAt und die biologischen Interaktionen berA1/4cksichtigen. Damit erreicht die PflanzenAkologie die Ebene der globalen StoffkreislAufe, die vor allem in Hinblick auf die anthropogenen Eingriffe in die Natur und die sich abzeichnende Bewirtschaftung des Kohlenstoffkreislaufs dargestellt werden. Das Buch behandelt nicht nur natA1/4rliche Vegetationen, sondern auch Akologische Aspekte der Land- und Forstwirtschaft. Das Lehrbuch der PflanzenAkologie richtet sich vor allem an Biologiestudenten sowie Wissenschaftler der Botanik, der Geowissenschaften und der LandschaftsAkologie. Es ist auch gedacht als Grundlage fA1/4r alle, die mit Land- und Forstwirtschaft, Landnutzung und mit Eingriffen in die Landschaft zu tun haben.

Scientific Opinion On The Pest Categorisation Of Tomato Yellow Leaf Curl Virus And Related Viruses Causing Tomato Yellow Leaf Curl Disease In Europe

Abstract: The Panel on Plant Health performed for the European Union (EU) territory a pest categorisation of Tomato yellow leaf curl virus (TYLCV) and three related viruses, Tomato yellow leaf curl Sardinia virus (TYLCSV), Tomato yellow leaf curl Axarquia virus (TYLCAxV) and Tomato yellow leaf curl Malaga virus (TYLCMaV), which collectively cause the tomato yellow leaf curl disease (TYLCD) in Europe. The viruses are well‐defined species of the genus Begomovirus, are exclusively transmitted by members of the Bemisia tabaci species complex and have tomato, as well as a few other crops or weeds, as their hosts. TYLCV is listed on tomato plants for planting, other than seeds, in Annex IIAII of Directive 2000/29/EC. While establishment and local spread rely on the Bemisia vector, the viruses can also be disseminated over long distances by movement of infected plants for planting or by consignments of non‐host plants carrying viruliferous whiteflies. Establishment outdoors and spread are limited to regions with ecoclimatic conditions suitable for the establishment of vector populations in the open. Outbreaks can nevertheless occur in other regions under protected cultivation conditions. Because of the very high potential impact of TYLCD, tomato production in affected regions requires intensive crop management efforts to reduce impact. TYLCV appears to be present in almost all EU regions with suitable ecoclimatic conditions for its establishment in open fields, while the other three viruses do not appear to have reached their full establishment potential. All four viruses are absent from other regions of the EU but have the potential to cause temporary outbreaks there.

This book focuses primarily on diseases of field and greenhouse-grown vegetable crops that are caused by pathogens. Chapters dealing with the general principles of the causes, diagnosis and control of vegetable crop diseases are followed by crop-based chapters. Each entry includes a brief introduction to the disease, detailed description of symptoms, information on the pathogen and disease development, and suggestions on how to manage the problem. Top quality color photos illustrate the book throughout. The book contains technical information of interest to researchers, scientists, technicians and educators in plant pathology and agriculture, as well as practical, field-oriented information of use to farmers, field personnel and the agricultural industry.

This book describes interactions of plant viruses with hosts and transmission vectors in an agricultural context. Starting with an overview of virus biology, economics and management, chapters then address economically significant plant diseases of tropical and subtropical crops. For each disease, symptoms, distribution, economic impact, causative virus, taxonomy, host range, transmission, diagnostic methods and management strategies are discussed.
