Download or read book Studies on the Mechanisms of Plant Virus Infection in Two Leguminous Protoplast Systems I Bean Pod Mottle Virus Infection of Suspension Culture Derived Soybean Protoplast II Infection of Bean Leaf Protoplast with Bean Pod Mottle and Cowpea Mosaic Viruses written by M. S. Lesney and published by . This book was released on 1980 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protoplasts derived from soybean (Glycine max L. cv. 'Harosoy 63') liquid suspension cultures were inoculated with Bean Pod Mottle Virus (BPMW) in order to ascertain the effects of various inoculum amendments on the virus infection system with the ultimate goal of elucidating possible infection mechanisms. Among the parameters examined were the effects of virus concentration, protoplast concentration, buffer (pH and concentration), poly-ornithine (PLO), calcium or magnesium chloride, and temperature on percentage infection obtained. Virus concentration effects showed a sigmoidal increase in infection with concentration increase. Protoplast concentration showed an inverse relationship to infection. Potassium phosphate buffer showed a strong optimum for infection at pH 5.6. This was used as partial evidence for the involvement of histidine in the infection process. Effects of buffer concentration were pH dependent. PLO was not required for BPMV infection, but was found to be stimulatory. A synergistic effect on increasing virus infection was demonstrated between PLO and CaCl2 at low virus concentrations. CaCl2 proved more stimulatory to BPMV infec tion than did MgCl2. Pre-incubation experiments for both buffer and the divalent cations showed that pre- incubation with the virus was nessary for most of the stimulatory effect to be obtained, but that PLO-induced infection was actually somewhat improved wheh pre-incubation was not allowed: BPMV was relatively temperature independent in the presence of inoculum amendments (buffer, PLO, CaCl2), but temperature dependent in their absence; infection then was better at higher temperatures. Protoplasts were isolated from bean (Phaseolus vulgaris L. cv. 'Pencil Pod Wax ') leaves and infected with both BPMV and cowpea mosaic virus (CPMV) in order to compare infection for the two viruses in the two different systems. The same PLO/calcium synergy was evident as in the soybean system. The optimum pH in the bean system for BPMV was 5.6. The primary difference observed between the two ystems was the ability of pH 6.0 buffer to eliminate the PLO/calcium synergy when present in the bean system, but not in the soybean system for both viruses. The similarities seen between the leaf and suspension culture protoplasts were suggestive of the latter being equally 'natural' as a system, as well as one which is more reliable. The kind and number of the complexities seen in the two virus/protoplast systems were advanced as circumstantial evidence for the possibility of receptor mediated endocytosis as the mode of infection by plant viruses in protoplasts-especially when considering such a theory as an alternative to the membrane 'wouding' hypothesis.

Download or read book Seed borne plant virus diseases written by K. Subramanya Sastry and published by Springer Science & Business Media. This book was released on 2013-01-05 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seeds provide an efficient means in disseminating plant virus and viroid diseases. The success of modern agriculture depends on pathogen free seed with high yielding character and in turn disease management. There is a serious scientific concern about the transmission of plant viruses sexually through seed and asexually through plant propagules. The present book provides the latest information along with the total list of seed transmitted virus and viroid diseases at global level including, the yield losses, diagnostic techniques, mechanism of seed transmission, epidemiology and virus disease management aspects. Additional information is also provided on the transmission of plant virus and virus-like diseases through vegetative propagules. It is also well known that seed transmitted viruses are introduced into new countries and continents during large-scale traffic movements through infected germplasm and plant propogules. The latest diagnostic molecular techniques in different virus-host combinations along with disease management measures have been included. The book shall be a good reference source and also a text book to the research scientists, teachers, students of plant pathology, agriculture, horticulture, life sciences, green house managers, professional entrepreneurs, persons involved in quarantines and seed companies. This book has several important features of seed transmitted virus diseases and is a good informative source and thus deserves a place in almost all university libraries, seed companies and research organizations.

Download or read book Plant microbe Interactions 2 written by Gary Stacey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-Microbe Interactions, Volume 2 Volume 1 of this series has made its appearance and dealt forcefully with impor tant current topics in the field of plant-microbe interactions. We believe that the quality of those chapters was high and should serve as a focal point for the state of the art as well as an enduring reference. Volume 2 builds upon these accom plishments. Chapter 1 discusses the fascinating lipo-chitin signal molecules from Rhizo bium, aspects regarding their biosynthesis, and the basis for host specificity. These molecules are a cardinal example of how microorganisms influence plant development and stimulate speculation that they have identified a previously un known aspect of plant hormone activity. Chapter 2 continues the discussion of Rhizobium by considering the trafficking of carbon and nitrogen in nodules. Al though the ostensible advantage of nodules to plants is the fixation of atmos pheric nitrogen, the actual process involved in supplying reduced nitrogen to the plant host is complex.

This book was released on 2015-06-26 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The broad host range pathogenic bacterium Agrobacterium tumefaciens has been widely studied as a model system to understand horizontal gene flow, secretion of effector proteins into host cells, and plant-pathogen interactions. Agrobacterium-mediated plant transformation also is the major method for generating transgenic plants for research and biotechnology purposes. Agrobacterium species have the natural ability to conduct interkingdom genetic transfer from bacteria to eukaryotes, including most plant species, yeast, fungi, and even animal cells. In nature, A. tumefaciens causes crown gall disease resulting from expression in plants of auxin and cytokinin biosynthesis genes encoded by the transferred (T-) DNA. Gene transfer from A. tumefaciens to host cells requires virulence (vir) genes that reside on the resident tumor-inducing (Ti) plasmid. In addition to T-DNA, several Virulence (Vir) effector proteins are also translocated to host cells through a bacterial type IV secretion system. These proteins aid in T-DNA trafficking through the host cell cytoplasm, nuclear targeting, and T-DNA integration. Genes within native T-DNAs can be replaced by any gene of interest, making Agrobacterium species important tools for plant research and genetic engineering. In this research topic, we provided updated information on several important areas of Agrobacterium biology and its use for biotechnology purposes.
