Tubule-forming capacity of the movement proteins of alfalfa mosaic virus and brome mosaic virus.

Systemic transport of Alfalfa mosaic virus can be mediated by the movement proteins of several viruses assigned to five genera of the 30K family.

We previously showed that the movement protein (MP) gene of Alfalfa mosaic virus (AMV) is functionally exchangeable for the cell-to-cell transport of the corresponding genes of Tobacco mosaic virus (TMV), Brome mosaic virus, Prunus necrotic ringspot virus, Cucumber mosaic virus and Cowpea mosaic virus. We have analysed the capacity of the heterologous MPs to systemically transport the correspon...

بررسی ویروس موزاییک یونجه در مناطق شمالی و مرکزی استان خراسان

The study of dispersion of alfalfa mosaic virus (ALMV) infection based on DAS-ELISA indicated that the fields of Alfalfa, potatoes and tomatoes from Chenaran, Ghochan, Shirvan, Mashhad, Neishaboor and Torbat Heydarieh were infected with the virus. The Statistical analysis indicated that the amount of infection did not differ in the surveyed regions and total mean of infection was 53 percent. Th...

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

The nucleotide sequence of RNA-1 of raspberry bushy dwarf virus.

Raspberry bushy dwarf virus (RBDV) has isometric, 33 nm diameter particles and a bipartite RNA genome. Sequencing of the larger component (RNA-1) showed that it consists of 5449 nucleotides and contains one large open reading frame encoding a putative translation product with a calculated M(r) of 190,000. Comparisons of this polypeptide with non-structural proteins of other plant viruses reveal...
