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...

Potato spindle tuber viroid (PSTVd) is a harmful quarantine disease with wide geographic distribution. To date, experimentally proved resistance or tolerance of potato cultivars to PSTVd has not been reported. The aim this study was evaluate responses four strains 39 modern different origin. Four origin, the intermediate VP35, VP87, and two sever FP10-13 NicTr-3, deposited in GenBank, were used...

Abstract Over the past decades, two new strains of potato virus Y (PVY N-Wi (Wilga) and PVY NTN ) have been most widely distributed worldwide in crops ( Solanum tuberosum L.). Effective resistance genes comprehensive against all known are available some commercial cultivars. However, not cultivars challenged by to confirm effectiveness resistances available. This study was set identify resistan...

Modern methods of pest control have tended to rely on a single method, whether it be a pesticide or a gene coding for resistance embedded using modern biotechnology tools in the crop itself. An important advantage of integrated pest management (IPM) over reliance on a single tool is that the repeated application of the single method rapidly leads to pest resistance to the tool. Using a variety ...
