Book Synopsis Plant Host Parasite Relationship by : Sarika Garg
Download or read book Plant Host Parasite Relationship written by Sarika Garg and published by Delve Publishing. This book was released on 2017-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The host and the parasite are the two different biological organisms involved in host parasite interactions. The parasite or pathogen is a benefited organism which is dependent on the host for its existence. The host and the parasite live in close proximity and the latter enjoys at the expense of the first. The parasite is like an intruder for the host which it wants to eliminate by various responsive reactions and resistance. In response, parasite generates several features such as polyembryony, production of special enzymes, increased fecundity, self-habitat, etc. This close association is referred to as host parasite interactions. Different types of parasites have been recognized on different basis. In terms of host specificity, parasites may be mono-specific or poly-specific. Mono-specific parasite restricts to a single host whereas poly-specific might associate with different genetically related hosts. Eventually, a mutual relation between the host and the parasite develops which allows them to survive together. The fatal parasites, however, try to kill the hosts. But killing the hosts will lead to the death of parasites itself. Host characteristics might be affected by intimate association with the parasite. These may include damage of tissue, necrosis, hyperplasia, neoplasia, malnourishment, etc. There are several parasitic plants and fungi which attack the plants. Parasitic plant extracts its resources from the vascular system of another living plant (host) using a specialized transfer organ called haustorium. Some examples of parasitic plants include Mistletoes, Yellow Rattle (Rhinanthus), Red Bartsia (Odontites) and Eyebrights (Euphrasia). These are hemi-parasitic members and have their own green leaves. Plants like Toothworts (Lathraea) and Broomrapes (Orobanche) are the examples of holo-parasitic plants which have no photosynthetic green leaves of their own. The Dodders (Cuscuta) are another common group of parasites. This book discusses the plant host parasite relationship and is a gathering of few research papers on interactions of parasitic plants/fungi with the host plants. The first three chapters throw light on the overview of host parasite interactions in plants. Chapter 4 describes the genetic transfer facilitation among plants by the association between the host and the parasite. The next chapter focuses on the interaction of Cuscuta reflexa with tomato plant. The molecular events during the parasitic plant host interaction are described in chapter 6. The next chapter covers the applicability of Limiting Resource Model (LRM) for understanding the effects of drought on tolerance to holoparasite Cuscuta gronovii. Chapter 8 discusses the compatibility or incompatibility of hosts by screening the response of four plant species of Solanaceae family to the parasitism of Cuscuta campestris Yuncker. Horizontal gene transfer between the host and the parasite nuclear genomes; and the consequences of Orobanche crenata infection severity in different legume crops viz. faba bean, field pea and grass pea have been discussed in chapters 9 and 10, respectively. Chapter 11 evaluates the effect of amino acids as herbicides for field control of Orobanche minor parasitism in red clover. The relationships of the parasitic plant Phelipanche ramosa (L.) and different hosts; and the microbiome of the parasitic weed Phelipanche aegyptiaca and tomato is described in the following two chapters, respectively. The last chapter discusses how water influences the effects of stem hemiparasites on hosts.

Book Synopsis Integrating New Technologies for Striga Control by : Gebisa Ejeta
Download or read book Integrating New Technologies for Striga Control written by Gebisa Ejeta and published by World Scientific. This book was released on 2007 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Witchweeds (Striga species) decimate agriculture in much of Africa and parts of Asia, attacking the major cereal grains and legumes, and halving the already very low yields of subsistence farmers. Several years of research have provided promising technologies, based on the fundamental biology of the parasite?host associations, for dealing with this scourge. However, there is an apparent realization that these technologies will fail because highly successful weeds such as Striga evolve resistance to all types of controls unless proven methods are integrated with each other for a more sustainable solution.Integration is often an anathema to basic scientists who typically deal with single variables and solutions. However, key leaders in the development of the new knowledge-based control strategies, already in the field and under development, recently joined forces to develop strategies and projects in order to integrate the technologies in a symposium in Ethiopia in November 2006. The encouraging results are described in this peer-reviewed book, authored by leaders in the field who have been supplying the basic biology, genetics, biochemistry, and molecular information that have offered insights and generated technologies in how to deal with Striga.

Book Synopsis Parasitic flowering plants by : Henning Heide-Jørgensen
Download or read book Parasitic flowering plants written by Henning Heide-Jørgensen and published by BRILL. This book was released on 2008-07-31 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic flowering plants are strikingly impressive and beautiful and hold many surprises of both general and scientific interest. Parasites also have great influence on the quality of human life when attacking crop plants. Some parasites have since early times appealed to our imagination and have been part of religious or folkloristic events and used as gifts to royalties. This beautifully illustrated book covers all parasitic families and most of the genera. It also discusses the establishment of the parasite, the structure and function of the nutrient absorption organ (haustorium), and how the parasites are pollinated and dispersed as well as their ecology, hosts, and evolution. The book is written in a mostly non-technical language and is provided with a glossary and explanatory boxes. For additional information about this book, including some sample photographs, as well as a list of corrections that have been incorporated in the 2011 reprint, please visit the author's web site. Parasitic Flowering Plants was nominated by The Council on Botanical and Horticultural Libraries for the 2010 Annual Award for a Significant Work in Botanical or Horticular Literature, in the category ‘Technical Interest’.

Book Synopsis The Rasputin Effect: When Commensals and Symbionts Become Parasitic by : Christon J. Hurst
Download or read book The Rasputin Effect: When Commensals and Symbionts Become Parasitic written by Christon J. Hurst and published by Springer. This book was released on 2016-07-05 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host’s capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host’s protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.
Book Synopsis Physiological Plant Pathology by : R. Heitefuß
Download or read book Physiological Plant Pathology written by R. Heitefuß and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant pathology embraces all aspects of biological and scientific activity which are concerned with understanding the complex phenomena of diseases in plants. Physiological plant pathology represents those specialities within plant pathology which focus on the physiological and biochemical activities of pathogens and on the response of host plant tissues. Today there is an increasing recognition on the part of the scientific agri cultural community that only through a deeper and more fundamental under standing of all the interacting components of the agricultural biota can we expect to improve our capabilities of feeding an expanding world population. It is in this context that physiological plant pathology has assumed new significance within the broader field of plant pathology. No longer are studies on the biochemistry and physiology of pathogens and pathogenesis merely isolated academic exercises; rather, a substantial coherent body of knowledge is accumulating upon which our understanding of the process of disease developmen t and host resistance is being founded. It is from these foundations of knowledge that ultimately new insights into the control of plant diseases may be expected to grow. It seems appropriate, therefore, that at regular intervals those involved in the various subspecialities encompassing the broadest aspects of physiological plant pathology reassess the contributions within the particular specialities in the light of new knowledge and technologies for the purpose of articulating new and productive directions for the future.

Book Synopsis Ecology and Physiology of Parasites by : A. Murray Fallis
Download or read book Ecology and Physiology of Parasites written by A. Murray Fallis and published by University of Toronto Press. This book was released on 1971-12-15 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing wisdom and ingenuity are required if we are to master our environment and cope with the myriad of organisms that affect our existence. Not the least of these organisms are the parasites and pathogens which can be found in all animals. The ecological implications of parasitism are obvious, and the interrelationships among different organisms within the same host are fascinating, but more knowledge and understanding are needed. The symposium are held to stimulate discussion of the significance of ecological problems presented by parasites and to develop means of attacking some of these problems. The diversity of parasitism from protozoa to anthropods was emphasized and the speakers and topics were selected to interest those in various biological disciplines and professions. Organized by the Department of Parasitology in the School of Hygiene of the University of Toronto, and held at Toronto in February 1970, the symposium was an unqualified success. The enthusiastic interest, indicated by the attendance of over three hundred people from seven countries, and numerous requests for copies of the proceedings led to the publication in this volume of the twelve papers presented at the symposium. The opening remarks of the leader of the discussion which follow each paper have been included and a complete bibliography is provided for each topic. The contributors are leading specialists in their fields; their papers present the results of the most recent research and assemble and review the scattered literature on each topic. The text is illustrated throughout with diagrams and photographs. Parasitism and associated phenomena are excellent examples of problems requiring the interdisciplinary approach taken by the symposium. The results of such an approach are useful in a wide variety of disciplines: microbiology, invertebrate zoology, entomology, and tropical medicine, as well as parasitology.
