Molecular Characterization of the Coat Protein Genome of Alfalfa Mosaic Virus (AMV) Isolates from Alfalfa in Van Province

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 ...

host range and partial molecular characterization of alfalfa mosaic virus isolates in kerman province

alfalfa mosaic virus (almv) is one of the most conspicuous alfalfa viruses in the world. in order to identify the distribution, host range and molecular characterization of alfalfa mosaic virus in kerman province, 514 alfalfa samples showing mosaic, calico, mottle and malformation symptoms as well as 66 potato samples showing calico symptoms were collected from alfalfa and potato fields in kerm...

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

Amino acids of alfalfa mosaic virus coat protein that direct formation of unusually long virus particles.

In contrast to most alfalfa mosaic virus (AMV) strains (YSMV, S, M and 425), AMV strains VRU and 1 5/64 can form abnormally long virus particles, an ability which has been linked to the coat protein (CP). In order to study this phenomenon, the CP-encoding RNAs 3 of AMV strains VRU and 1 5/64 were cloned and fully sequenced. Comparative sequence analyses of AMV RNA 3 sequences derived from diffe...

Structural elements of the 3'-terminal coat protein binding site in alfalfa mosaic virus RNAs.

The 3'-terminal of the three genomic RNAs of alfalfa mosaic virus (AIMV) and ilarviruses contain a number of AUGC-motifs separated by hairpin structures. Binding of coat protein (CP) to such elements in the RNAs is required to initiate infection of these viruses. Determinants for CP binding in the 3'-terminal 39 nucleotides (nt) of AIMV RNA 3 were analyzed by band-shift assays. From the 5'- to ...
