توسعه سطح کشت توت فرنگی (fragaria sp.) در سال های اخیر به دلیل درآمدزایی آن برای کشاورزان در کشور مورد توجه قرار گرفته است. با توجه به اهمیت کشت این محصول در استان های گیلان و مازندران و از طرفی اهمیت بیماری های ویروسی در کاهش کمی و کیفی این محصول، در این تحقیق وضعیت بیماری های ویروسی توت فرنگی در این دو استان مورد بررسی قرار گرفت. طی سال 1391 و 1392 در مجموع تعداد 422 نمونه تصادفی و 223 نمونه ...
Genetical and biochemical evidence indicates that herpes simplex virus (types and 2) specifies a unique kinase activity which is able to phosphorylate both thymidine and deoxycytidine. Pseudorabies virus specifies an enzyme which has only thymidine kinase activity and so does vaccinia virus, while equine abortion virus does not induce either activity. It is shown that the HSV specified deoxypyr...
In a companion paper (D. Ostertag, T. M. Hoblitzell-Ostertag, and J. Perrault, J. Virol. 81:492-502, 2007), we provided indirect evidence that cell-type-specific growth restriction of the vesicular stomatitis virus (VSV) polR mutants may be due to enhanced production of double-stranded RNA (dsRNA). We show here that polR growth in mouse L-929 cells was rescued by vaccinia virus coinfection and ...
Procedures are described for modification of the phospholipid polar head group and fatty acid composition of normal and Rous sarcoma virus-infected chicken embryo fibroblasts. Lipid modification was carried out by growth of cells in delipidated medium containing either polar head group analogues or specific fatty acids. Normal and infected cells displayed similar kinetics of lipid alteration, a...
The oligosaccharides of the membrane glycoproteins of Sindbis virus, vesicular stomatitis virus, and Rous sarcoma virus were compared on the basis of apparent size and sugar composition. It appears that each virus acquires a different set of oligosaccharides during growth in a single type of cell.
The XC rat cell line was found to support the replication of a strain of the Moloney murine sarcoma-leukemia virus. In growth curve experiments cytopathology was paralleled by the production of murine sarcoma virus and leukemia virus progeny having the biologic, antigenic, and biophysical properties of the infecting virus.
Infection of A431 cells with vaccinia virus, or exposure to a mitogenic polypeptide secreted by vaccinia virus-infected cells, induces tyrosine phosphorylation of epidermal growth factor receptors.
Passatempo virus was isolated during a zoonotic outbreak. Biologic features and molecular characterization of hemagglutinin, thymidine kinase, and vaccinia growth factor genes suggested a vaccinia virus infection, which strengthens the idea of the reemergence and circulation of vaccinia virus in Brazil. Molecular polymorphisms indicated that Passatempo virus is a different isolate.
