A century of tobamovirus evolution in an Australian population of Nicotiana glauca.
The evolution over the past century of two tobamoviruses infecting populations of the immigrant plant Nicotiana glauca in New South Wales (NSW), Australia, has been studied. This plant species probably entered Australia in the 1870s. Isolates of the viruses were obtained from N. glauca specimens deposited in the NSW Herbarium between 1899 and 1972, and others were obtained from living plants in...
متن کاملCarboxylate interactions involved in the disassembly of tobacco mosaic tobamovirus.
Structural studies of tobacco mosaic tobamovirus (TMV) have identified two coat protein (CP) intersubunit carboxyl-carboxylate interactions and one CP carboxylate-RNA phosphate interaction whose electrostatic repulsion is believed to drive virion disassembly. In this study, the involvement of each interaction in the disassembly process was examined. Site-directed mutagenesis was used to replace...
متن کاملStudy on Genetic Diversity of Terminal Fragment Sequence of Isolated Persian Tobacco Mosaic Virus
Tobacco mosaic virus (TMV) is one of the devastating plant viruses in the world that infects more than 200 plant species. Movement protein plays a supportive role in the movement of other plant viruses, and viral coat protein is highly expressed in infected plants and affects replication and movements of TMV. In order to investigate genetic variation in the terminal fragment sequence in Iranian...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Similarities between the secondary structure of satellite tobacco mosaic virus and tobamovirus RNAs.
The secondary structure of satellite tobacco mosaic virus (STMV) RNA was predicted using computer simulations of RNA folding. The analogies of structural elements in the 3' end untranslated regions (3'-UTR) of tobamoviral RNAs were analysed. In addition to the tRNA-like structure and pseudoknot stalk, which are found in all known RNAs of tobamoviruses and STMV, another region of stable consecut...
