The C-terminal region of the movement protein of Cowpea mosaic virus is involved in binding to the large but not to the small coat protein.

Study on Genetic Diversity of Terminal Fragment Sequence of Isolated Persian Tobacco Mosaic Virus

Tobacco mosaic virus (TMV) is one of the devastating plant viruses in the world that infects more than 200 plant species. Movement protein plays a supportive role in the movement of other plant viruses, and viral coat protein is highly expressed in infected plants and affects replication and movements of TMV. In order to investigate genetic variation in the terminal fragment sequence in Iranian...

Characterization of Coat Protein Gene of Cucumber Mosaic Virus Isolates in Iran

Background: Cucumber mosaic virus (CMV) from the Bromoviridae family, is one of the most widespread plant viruses in the world. Objectives: In the present study tomato fields in Guilan, Isfahan, Khorasan Razavi, Khuzestan and Tehran provinces were surveyed to determine the presence of CMV subgroups during 2011-2012. Materials and Methods: Out of 305 symptomatic leaf samples ...

Partial Epitope Mapping of Alfalfa mosaic Virus and the Effect of Coat Protein Gene Mutation on Aphid Transmission

The Effect of High Temperature Treatment on Wheat Streak Mosaic Virus Resistance and Certain Resistance-Related Chemicals in Bread Wheat

Background and Aims: To evaluate the effect of temperature on wheat streak mosaic virus (WSMV) resistance phenotype, through total protein, phenol, and peroxidase activity in bread wheat, a factorial experiment was conducted using Adl-Cross (resistant) and Marvdasht (susceptible) cultivars. Materials and Methods: Results showed that incubation at 32C changed the gene expression for resistance ...

Molecular detection of proteolytic activity of human parechovirus 2A protein by gene expression

  Parechoviruses form one of the nine genera in the picornaviridae family, and include two human pathogens: Human parechovirus type1 and 2 (Hpev1 and Hpev2). The genome of picornaviruses encodes a single polyprotein, which undergoes a cleavage cascade performed by virus encoded proteases to give the final virus proteins. The primary cleavage occurs by 2A protein and this step is critical for vi...
