In 1992 a Concerted Action Programme (CAP) was initiated by Peter Sijmons with the purpose of intensifying collaborations between 16 European laboratories working on plant-parasitic nematodes. The four-year programme entitled `Resistance mechanisms against plant-parasitic nematodes' focused on molecular aspects of the interaction between sedentary nematodes and plants on the model system Arabidopsis and on novel resistance strategies. Funding was provided mainly for exchange visits between collaborating laboratories and for the organization of annual meetings. During the last annual meeting which was held in May 1996 in Toledo, Spain, Carmen Fenoll initiated the production of this volume. The book presents a series of up-to-date reviews, each written by one of the participating laboratories, which include the scientific progress achieved in the frame of this CAP but are by no means limited in scope to this work.
Humans face the challenge of producing enough food to meet the demands imposed by economic, biological and agricultural factors: rising population; rising income; and an expectation of higher quality food and a more diverse diet; decreasing amount of land available for food production; lowering environmental impact of agricultural practices and preserving biodiversity. Biotechnology is one of the most exciting and dynamic industries of our day. It offers us the possibility of reducing our dependence on intensive farming. Plant biotechnology is central to the search for effective, environmentally safe and economically sound alternatives to the use of chemical pesticides and the exhaustion of ...
Plant-parasitic nematodes (PPNs) devastate many crop plants, causing billions of dollars in agricultural losses each year. Effective management methods to combat PPNs are synthetic nematicides, but most are non-specific and notoriously toxic and threaten the soil ecosystem, groundwater and human health. The plant by-products, such as oilseed cakes, are sources of bioactive compounds with nematicidal potential. Oilseed cakes are an excellent organic fertilizer, and their bioactive compounds are now gaining importance as they are safe for the environment. This book provides the most comprehensive and up-to-date review of research on the use of oilseed cakes against PPNs. The complete knowledge...
Transfer cells are anatomically specialized cells optimized to support high levels of nutrient transport in plants. These cells trans-differentiate from existing cell types by developing extensive and localized wall ingrowth labyrinths to amplify plasma membrane surface area which in turn supports high densities of membrane transporters. Unsurprisingly, therefore, transfer cells are found at key anatomical sites for nutrient acquisition, distribution and exchange. Transfer cells are involved in delivery of nutrients between generations and in the development of reproductive organs and also facilitate the exchange of nutrients that characterize symbiotic associations. Transfer cells occur acr...
This book summarizes our current knowledge on belowground defence strategies in plants by world-class scientists actively working in the area. The volume includes chapters covering belowground defence to main soil pathogens such as Fusarium, Rhizoctonia, Verticillium, Phytophthora, Pythium and Plasmodiophora, as well as to migratory and sedentary plant parasitic nematodes. In addition, the role of root exudates in belowground plant defence will be highlighted, as well as the crucial roles of pathogen effectors in overcoming root defences. Finally, accumulating evidence on how plants can differentiate beneficial soil microbes from the pathogenic ones will be covered as well. Better understanding of belowground defences can lead to the development of environmentally friendly plant protection strategies effective against soil-borne pathogens which cause substantial damage on many crop plants all over the world. The book will be a useful reference for plant pathologists, agronomists, plant molecular biologists as well as students working on these and related areas.
Plant parasitic nematodes are a main pest to crops. For ex am pie, the root-knot nematodes belonging to the genus Meloidogyne are worldwide in their distribution and attack almost every type of crop, causing considerable losses of yield and affecting quality of produce. The cyst nematodes within the genera Globodera and Heterodera constitute a major group of plant pathogens in many countries throughout the world, suppressing yields of potato, sugar beet, soybean and cereals. Several nematodes such as longidorids and trichodorids are implicated in the transmission of numerous plant viruses. Many others cause constraints to agricultural production either locally or on large areas. However, des...
