Parasitic Plants
Parasitic plants are of great economic importance and cause huge crop losses worldwide. They present unique biological aspects and control problems. This title provides full coverage relating to the biology, diversity and control of parasitic flowering plants and will be of great use to plant scientists, agricultural and environmental scientists.
Parasitic Plants
There are always some exceptions found in the nature. For example, there are a group of plants called ‘parasitic plants’ which are unable to perform photosynthesis, a characteristic function of majority members of the plant kingdom. These parasitic plants depend on other living plants for their food and nutritional requirements. Parasitic plants that depend totally on other plants for their food and nutritional requirements are known as total parasites or holoparasites or obligately parasitic plants. Parasitic plants that depend partially on other plants for their food and nutritional requirements are called partial parasites or hemiparasites.

Parasitic flowering plants
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...
Parasitic Plants in African Agriculture
Parasitic Plants in African Agriculture brings together for the first time in a single volume, the ecology, biology, damage, and control of all groups of African parasitic plants including both the relatively few parasites introduced to the continent as well as those native parasites that have spread from within Africa. The book covers the well-known witchweeds and broomrapes but also groups and species that have received less attention including mistletoes, dodders, rice vampire weed, and other species posing threats. This book will be a valuable reference for students, researchers, extension workers, development officers, national agriculture researchers, plant pathologists, food security specialists, weed scientists, agronomists and botanists.
Parasitic Orobanchaceae
This book was written in response to significant recent advances in understanding the mechanisms of parasitism in the Orobanchaceae, and breakthroughs in the control of the parasitic weeds Striga and Orobanche. It consists of 26 contributions by internationally recognized leading scientists. The main book chapters are grouped into two parts: · Part I – The Orobanchaceae and Their Parasitic Mechanisms · Part II – The Weedy Orobanchaceae and Their Control The first part provides cutting-edge information on all key aspects of plant parasitism, such as the structure, development and function of the haustorium; nutrient transfer and the physiology of the parasite-host association; host reac...
Parasitic Plants as Vectors for Pathogens
Parasitic plants obtain their nutrition from their hosts. In addition to this direct damage, they cause indirect damage to their hosts by transmitting various plant pathogens. There are some 4,500 species of parasitic plants known; out of them, nearly 60% are root parasites and the rest of them parasitise on the shoot parts. Orobanchaceae and Convolvulaceae are the two mostly studied families of parasitic plants; and the parasitic plants are the chief mode for transmission of the phytoplasmas. The parasitic plants have various modes of obtaining nutrition; however, the information about the mechanism(s) involved in the pathogen transmission by the parasitic plants is limited. The latest biotechnolgical advances, such as metagenomics and high througput sequencing, carry immense promise in understanding the host-parasitic plant-pathogen association in deeper details; and initiatives have indeed been taken. Nevertheless, compared to the other pests hindering crop productivity, parasitic plants have not yet been able to gain the needed attention of the plant scientists. In this chapter, we review and present some of the latest advances in the area of these important plant pests.
Advances in Parasitic Weeds Research
Parasitic weeds are severe constraint to agriculture and major crop production, and the efficacy of available means to control them is minimal. Control strategies have centred around agronomic practices, resistant varieties and the use of herbicides. Novel integrated control programmes should be sympathetic to agricultural extensification while exerting minimal harmful effects on the environment. This eBook covers recent advances in biology, physiology of parasitism, genetics, population dynamics, resistance, host-parasite relationships, regulation of seed germination, etc., in order to offer an outstanding windows to these enigmatic plants, and contribute to their practical management.
Plant Defense
Plants are sources of nourishment for thousands of fungi, bacteria, invertebrates, vertebrates, and other plants. Plants possess a truly remarkable diversity of mechanisms to fend off attackers and recent research has shown just how complex and sophisticated these defense mechanisms can be. Plant Defense provides comprehensive coverage of the range of different organisms that plants need to fend off, describes how plants coordinate their defenses against multiple attacks, explains the evolution of defense in plants, and how plant defences are exploited in crop protection strategies. Plant Defense: Covers plants’ defenses against pathogens, pests, and parasitic plants: together in one book ...
