Secondary structures of narcissus mosaic virus coat protein

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 ...

Nucleotide sequence of narcissus mosaic virus RNA.

The nucleotide sequence of the genomic RNA of narcissus mosaic virus (NMV) was deduced from a set of cDNA clones and by direct sequencing of RNA. The genome, with a length of 6955 nucleotides [excluding the 3'poly(A) tail], contains six open reading frames (ORFs) with the capacity to code for polypeptides of more than 10K, with Mr values of 186284, 25845, 13998, 11059, 26097 and 10519. The firs...

Nuclear targeting of the cauliflower mosaic virus coat protein.

The entry of the viral genomic DNA of cauliflower mosaic virus into the nucleus is a critical step of viral infection. We have shown by transient expression in plant protoplasts that the viral coat protein (CP), which is processed from the product of open reading frame IV, contains an N-terminal nuclear localization signal (NLS). The NLS is exposed on the surface of the virion and is thus avail...

Characterization of Alternanthera mosaic virus and its Coat Protein

A new isolate of Alternantheramosaic virus (AltMV-MU) was purified from Portulaca grandiflora plants. It has been shown that the AltMV-MU coat protein (CP) can be efficiently reassembled in vitro under different conditions into helical RNA-free virus-like particles (VLPs) antigenically related to native virus. The AltMV-MU and VLPs were examined by atomic force and transmission electron micros...
