Induction of Resistance to Potato Virus Y (PVY) Using Hairpin Construct of Coat Protein
Potato virus Y (PVY) is one of the most damaging viruses of potato plants which infecting most cultivars and causing significant yield and economical losses. The application of the concept of pathogen derived resistance opened new horizons for the development of virus-resistant plants. This research was carried out to study RNA silencing to engineered potato plants that are resistant to potato ...
متن کاملThermal Denaturation Equilibria of Tmv Coat Proteins
Thermal denaturation of RNA free coat proteins of tobacco mosaic virus (TMV) was studied for wildtype TMV (vulgare) and the temperature-sensitive mutant, Ni 118. The ability to form soluble aggregates as well as the optical properties (ORD, UV-difference spectra), and the sedimen tation behavior were used as criteria for the native state. At pH 7.5 , 7 = 0 .0 2 denaturation is reversible for b...
متن کاملTobacco mosaic virus (TMV) and potato virus X (PVX) coat proteins confer heterologous interference to PVX and TMV infection, respectively.
Replication of Potato virus X (PVX) was reduced in transgenic protoplasts that accumulated wild-type coat protein (CPWT) of Tobacco mosaic virus (TMV) or a mutant CP, CP(T42W), that produced highly ordered states of aggregation, including pseudovirions. This reaction is referred to as heterologous CP-mediated resistance. However, protoplasts expressing a CP mutant that abolished aggregation and...
متن کاملConstruction and Quality Analysis of Transgenic Rehmannia glutinosa Containing TMV and CMV Coat Protein.
Plant viruses, especially tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV) are serious threats to Rehmannia glutinosa which is a "top grade" herb in China. In the present study, TMV- and CMV-resistant Rehmannia glutinosa Libosch. plants were constructed by transforming the protein (CP) genes of TMV and CMV into Rehmannia glutinosa via a modified procedure of Agrobacterium tumefaciens-...
متن کاملExpression of alfalfa mosaic virus coat protein in tobacco mosaic virus (TMV) deficient in the production of its native coat protein supports long-distance movement of a chimeric TMV.
Alfalfa mosaic virus (AlMV) coat protein is involved in systemic infection of host plants, and a specific mutation in this gene prevents the virus from moving into the upper uninoculated leaves. The coat protein also is required for different viral functions during early and late infection. To study the role of the coat protein in long-distance movement of AlMV independent of other vital functi...
