Abstract:

Tomato leaf curl virus (ToLCV) has appeared as a potential threat to the tomato production in the world. ToLCV, a member of the family Geminiviridae may contain either bipartite or monopartite genome. The genetic nature of a monopartite ToLCV isolate characterized from the tomato leaf curl diseased samples of Jamalpur district, Bangladesh (ToLCV-JB) has been reported. The products of rolling circle amplification (RCA) were digested, cloned and sequenced. Sequence analysis revealed the features of begomovirus genome organization in the ToLCV-JB isolate, containing six open reading frames. BLAST

Abstract:

Yellow vein mosaic or yellow leaf curl disease in tomato, okra and other pulses is transmitted by Bemisia tabaci (White fly), leading to loss of production and quality. Gene silencing is one of the powerful approaches to overcome viral based plant diseases. However it is of great challenge to design potential small interfering RNA (siRNA) molecules against genes responsible for the diseases. From the primary sequence information, using insilico approach, 15 siRNAs were designed for genes involved in pathogenicity like suppressor, movement and nuclear shuttle namely V2, C2 and C4 of monopartite

Abstract:

We report the asymmetric reconstruction of the single-stranded RNA (ssRNA) content in one of the three otherwise identical virions of a multipartite RNA virus, brome mosaic virus (BMV). We exploit a sample consisting exclusively of particles with the same RNA content—specifically, RNAs 3 and 4—assembled in planta by agrobacterium-mediated transient expression. We find that the interior of the particle is nearly empty, with most of the RNA genome situated at the capsid shell. However, this density is disordered in the sense that the RNA is not associated with any particular structure but rather

Tomato leaf curl disease (ToLCD) caused by Tomato leaf curl Karnataka virus (ToLCKV) is a serious threat to tomato production. It is a Begomovirus (Geminiviridae) with monopartite single stranded DNA and transmitted by whitefly.

Abstract:

The plant-infecting geminiviruses deliver their genome and viral proteins into the host cell nucleus. Members of the family Geminiviridae possess either a bipartite genome composed of two ∼2.6 kb DNAs or a monopartite genome of ∼3.0 kb DNA. The bipartite genome of Bean dwarf mosaic virus (BDMV) encodes several karyophilic proteins, among them the capsid protein (CP) and BV1 (nuclear shuttle protein). A CP is also encoded by the monopartite genome of Tomato yellow leaf curl virus (TYLCV). Here, an in vitro assay system was used for direct demonstration of nuclear import of BDMV BV1 and TYLCV CP

Background Begomoviruses are widely distributed and causing devastating diseases in many crops. According to the number of genomic components, a begomovirus is known as either monopartite or bipartite begomovirus. Both the monopartite and bipartite begomoviruses have the DNA-A component which encodes all essential proteins for virus functions, while the bipartite begomoviruses still contain the DNA-B component. The satellite molecules, known as betasatellites, alphasatellites or deltasatellites, sometimes exist in the begomoviruses. So, the genomic components of begomoviruses are complex and v

Efforts to identify a DNA B component were unsuccessful. These findings suggest that TbLCZWV is a new member of the monopartite group of begomoviruses. Phylogenetic analysi

Abstract:

In northwestern Argentina (NWA), pepper crops are threatened by the emergence of begomoviruses due to the spread of its vector, Bemisia tabaci (Gennadius). The genus Begomovirus includes pathogens that can have a monopartite or bipartite genome and are occasionally associated with sub-viral particles called satellites. This study characterized the diversity of begomovirus and alphasatellite species infecting pepper in NWA using a metagenomic approach. Using RCA-NGS (rolling circle amplification-next generation sequencing), 19 full-length begomovirus genomes (DNA-A and DNA-B) and one alphasatel

Abstract:

Little cherry disease (LChD) is a serious economic problem of sweet cherry production in western North America where apple mealybug is the principle vector. LChD is associated with a distinct species of double-stranded (ds) RNA. In this study, filamentous virus particles were purified from LChD-infected trees and shown to contain single-stranded RNA corresponding to the previously reported dsRNA isolated from infected trees. The virus particles were characterized and were similar to monopartite members of the genus Closterovirus. A portion of the genome was sequenced and found to be most close

Abstract:

Tomato leaf curl disease (ToLCD) is a significant constraint for tomato production in the Sultanate of Oman. The disease in the north of the country has previously been shown to be caused by the monopartite begomoviruses (family Geminiviridae) Tomato yellow leaf curl virus and Tomato leaf curl Oman virus. Many tomato plants infected with these two viruses were also found to harbor a symptom enhancing betasatellite. Here an analysis of a virus isolated from tomato exhibiting ToLCD symptoms originating from south and central Oman is reported. Three clones of a monopartite begomovirus were obtain

Abstract:

A new mycovirus was found in the Fusarium culmorum strain A104-1 originally sampled on wheat in Belgium. This novel virus, for which the name Fusarium culmorum virus 1 (FcV1) is suggested, is phylogenetically related to members of the previously proposed family ‘’Unirnaviridae’’. FcV1 has a monopartite dsRNA genome of 2898 bp that harbors two large non-overlapping ORFs. A typical -1 slippery motif is found at the end of ORF1, advocating that ORF2 is translated by programmed ribosomal frameshifting. While ORF2 exhibits a conserved replicase domain, ORF1 encodes for an undetermined protein. Inte

Abstract:

Numerous whitefly-transmitted viral diseases of tomato have emerged in countries around the Nile and Mediterranean Basins the last 20 years. These diseases are caused by monopartite geminiviruses (family Gemini viridae) belonging to the genus Begomovirus that probably resulted from numerous recombination events. The molecular biodiversity of these viruses was investigated to better appreciate the role and importance of recombination and to better clarify the phylogenetic relationships and classification of these viruses. The analysis partitioned the tomato-infecting begomoviruses from this reg

ABSTRACT Flaviviruses have a monopartite positive-stranded RNA genome, which serves as the sole mRNA for protein translation. Cap-dependent translation produces a polyprotein precursor that is co- and posttranslationally processed by proteases to yield the final protein products. In this study, using tick-borne encephalitis virus (TBEV), we constructed an artificial bicistronic flavivirus genome (TBEV-bc) in which the capsid protein and the nonstructural proteins were still encoded in the cap cistron but the coding region for the surface proteins prM and E was moved to a separate translation u

The investigation into molecular diversity is necessary to devise intervention techniques against these begomoviruses. Based on the outcome of diversity, preferred resistance strategy against a disease complex should be generic in nature, which provides an advantage of a broad range resistance against a var
