Incidence, complexity and diversity of simple sequence repeats across potexvirus genomes.

Alam CM1, Singh AK2, Sharfuddin C1, Ali S3.Author information 1Department of Botany, Patna University, Bihar 800005, India.2Department of Biomedical Sciences, SRCASW, University of Delhi, Vasundhara Enclave, New Delhi 110096, India.3Department of Biomedical Sciences, SRCASW, University of Delhi, Vasundhara Enclave, New Delhi 110096, India. Electronic address: safdar_mgl@live.in.AbstractAn in-silico analysis of simple sequence repeats (SSRs) in genomes of 32 species of potexviruses was performed wherein a total of 691 SSRs and 33 cSSRs were observed. Though SSRs were present in all the studied genomes their incident frequency ranged from 11 to 30 per genome. Further, 10 potexvirus genomes possessed no cSSRs when extracted at a dMAX of 10 and wherein present, the highest frequency was 3. SSR and cSSR incidence, relative density and relative abundance were non-significantly correlated with genome size and GC content suggesting an ongoing evolutionary and adaptive phase of the virus species. SSRs present primarily ranged from mono- to tri-nucleotide repeat motifs with a greatly skewed distribution across the coding and non-coding regions. Present work is an effort for the undergoing compilation and analysis of incidence, distribution and variation of the viral repeat sequences to understand their evolutionary and functional relevance.

P3N-PIPO of Clover yellow vein virus exacerbates symptoms in pea infected with White clover mosaic virus and is implicated in viral synergism.

Hisa Y1, Suzuki H1, Atsumi G2, Choi SH1, Nakahara KS3, Uyeda I1.Author information 1Pathogen-Plant Interactions Group, Plant Breeding Science, Research Faculty of Agriculture, Hokkaido University, Sapporo 060-8589, Japan.2Iwate Biotechnology Research Center, Kitakami 024-0003, Iwate, Japan.3Pathogen-Plant Interactions Group, Plant Breeding Science, Research Faculty of Agriculture, Hokkaido University, Sapporo 060-8589, Japan. Electronic address: knakahar@res.agr.hokudai.ac.jp.AbstractMixed infection of pea (Pisum sativum) with Clover yellow vein virus (ClYVV) and White clover mosaic virus (WClMV) led to more severe disease symptoms (a phenomenon called viral synergism). Similar to the mixed ClYVV/WClMV infection, a WClMV-based vector encoding P3N-PIPO of ClYVV exacerbated the disease symptoms. Infection with the WClMV vector encoding ClYVV HC-Pro (a suppressor of RNA silencing involved in potyviral synergisms), also resulted in more severe symptoms, although to a lesser extent than infection with the vector encoding P3N-PIPO. Viral genomic RNA accumulated soon after inoculation (at 2 and 4 days) at higher levels in leaves inoculated with WClMV encoding HC-Pro but at lower levels in leaves inoculated with WClMV encoding P3N-PIPO than in peas infected with WClMV encoding GFP. Our results suggest that ClYVV P3N-PIPO is involved in the synergism between ClYVV and WClMV during pea infection through an unknown mechanism different from suppression of RNA silencing.

Plant viral vectors for delivery by agrobacterium.

Gleba YY, Tusé D, Giritch A.Author information Nomad Bioscience GmbH, Weinbergweg 22, Halle (Saale), Germany, gleba@nomadbioscience.com.AbstractPlant viral vectors delivered by Agrobacterium are the basis of several manufacturing processes that are currently in use for producing a wide range of proteins for multiple applications, including vaccine antigens, antibodies, protein nanoparticles such as virus-like particles (VLPs), and other protein and protein-RNA scaffolds. Viral vectors delivered by agrobacterial T-DNA transfer (magnifection) have also become important tools in research. In recent years, essential advances have been made both in the development of second-generation vectors designed using the 'deconstructed virus' approach, as well as in the development of upstream manufacturing processes that are robust and fully scalable. The strategy relies on Agrobacterium as a vector to deliver DNA copies of one or more viral RNA/DNA replicons; the bacteria are delivered into leaves by vacuum infiltration, and the viral machinery takes over from the point of T-DNA transfer to the plant cell nucleus, driving massive RNA and protein production and, if required, cell-to-cell spread of the replicons. Among the most often used viral backbones are those of the RNA viruses Tobacco mosaic virus (TMV), Potato virus X (PVX) and Cowpea mosaic virus (CPMV), and the DNA geminivirus Bean yellow dwarf virus. Prototypes of industrial processes that provide for high yield, rapid scale up and fast manufacturing cycles have been designed, and several GMP-compliant and GMP-certified manufacturing facilities are in place. These efforts have been successful as evidenced by the fact that several antibodies and vaccine antigens produced by magnifection are currently in clinical development.
