Heterologous Expression of Potato Virus Y Coat Protein, Isolate Pot187
Background: The advent of recombinant DNA technology has facilitated heterologous expression of proteins from various sources in different host systems including Escherichia coli. If a plant virus coat protein is expressed in the bacterium it can be used as the antigen for antibody preparation. Such a recombinant antigen preparation can be particularly useful where equipment such as ultracentri...
متن کاملPhylogeography and Molecular Evolution of Potato virus Y
Potato virus Y (PVY) is an important plant pathogen, whose host range includes economically important crops such as potato, tobacco, tomato, and pepper. PVY presents three main strains (PVY(O), PVY(N) and PVY(C)) and several recombinant forms. PVY has a worldwide distribution, yet the mechanisms that promote and maintain its population structure and genetic diversity are still unclear. In this ...
متن کاملBiological, serological and molecular typing of potato virus Y (PVY) isolates from Tunisia.
In Tunisia, potato virus Y (PVY) currently presents a significant threat to potato production, reducing tuber yield and quality. Three hundred and eighty-five potato samples (six different cultivars) collected in autumn 2007 from nine regions in Tunisia were tested for PVY infection by DAS-ELISA. The virus was detected in all regions surveyed, with an average incidence of 80.26%. Subsequently, ...
متن کاملSequence characteristics of potato virus Y recombinants.
Potato virus Y (PVY) is one of the most economically important plant pathogens. The PVY genome has a high degree of genetic variability and is also subject to recombination. New recombinants have been reported in many countries since the 1980s, but the origin of these recombinant strains and the physical and evolutionary mechanisms driving their emergence are not clear at the moment. The replic...
متن کاملMolecular Characterization of Pasteurella multocida Isolated from Rabbit in Egypt
Objective: The study aimed to molecular characterization of Pasteurella multocida local strain using Enterobacterial Repetitive Intergenic Consensus (ERIC), 13 virulence genes and the outer membrane protein (OmpH) gene. Also, development of diagnostic markers by multiplex PCR from investigated genes. Methodology: The ERIC-PCR was used for the detection of the finger print of Pasteurella multoci...
