AN ASSIGNMENTONPHYSIOLOGICAL EFFECTS OF VIRUS INFECTEDPLANTSSUMITTED BY:ROUF AHMADL-2011-BS-249-MSUBMITTED TO:Prof. Dr. S.S. KANGDeptt. All viruses that spread within their host tissues (systemically) can be transmitted by grafting branches or buds from diseased plants on healthy plants. metabolism of the host plant. Asked by Wiki User. The study of the chemistry of virus-infected cells cannot yet claim a molecu- lar interpretation for the genesis of the viral cytopathic effect. Several genes in the biosynthetic pathways for scopolamine, nicotine, and berberine have been cloned, making the metabolic engineering of these alkaloids possible. Presentation Summary : NITROGEN METABOLISM animals plants fungi Nitrogen is essential for all organisms (in amino acids and nucleic acids). 0 0 1. Asked by Wiki User. The CU highlights the need and the relevance of integrating metabolic events within the plant and its environment. Understand the roles of the NAD +/NADH and FAD/FADH 2 coenzymes in the transfer of electrons. It is easy to validate this statement—one just needs to recall that nucleotides are the building blocks of DNA and RNA, and that many molecules that are central for metabolism, for example ATP, NADH, Co-A, and UDP-Glc, are nucleotides or contain nucleotide moieties. In this paper, we discuss (1) activity of chlorophyllase, (2) ferrous and ferric iron changes, (3) inorganic and organic phosphorus, and (4) respiration in pigeon pea sterility mosaic infected pigeon pea plants and cassava mosaic infected cassava plants. Plant cutting and grafting are common modes by which plant viruses may be transmitted. NITROGEN METABOLISM animals plants fungi Nitrogen is essential for all organisms PPT.

Wilbur Ackermann Department of Epidemiology and Virus Laboratory, School of Public Heallh, University of Michigan, Ann Arbor, Mich. Plant metabolism produces volatile cues that are used to detect a food source for herbivores 58 (Figure 6).In response to such challenges, plants have evolved chemical defense systems for protection against herbivory that are comprehensively reviewed elsewhere. Unique plant biochemical features and how they relate dynamically to plant performance will be considered, i.e. Plant disease - Plant disease - Transmission: With the exception of tobacco mosaic virus, relatively few viruses or viroids are spread extensively in the field by contact between diseased and healthy leaves. Little information is available on the sequence of physiological changes from virus inoculation to full development of disease symptoms. 2.  Too small to be seen with a light microscope 3. Plant Resistance to Viruses Mediated by Translation Initiation Factors from Olivier Le Gall, Miguel A. Aranda and Carole Caranta writing in Recent Advances in Plant Virology Host resistance to viruses can show dominant or recessive inheritance. When healthy and infected plants were compared a reduction in the contents of chlorophylls, soluble proteins and nitrogen was evident in infected leaves.

There are two major physiological effects of virus infection in plants which may be summarized as follows: Respiratory activities are markedly increased very early during the course of the infection which corresponds to the period of arrival of virus particles from points of infection. In fungi SPD is the most important PA, which involved in all the functions such as the regulation of cell proliferation and differentiation, vegetative growth, spore germination, sporulation or dimorphic transition, probably in all fungi [2-4.
