Evolutionary relationships and systematics of the alphaviruses.
Partial E1 envelope glycoprotein gene sequences and complete structural polyprotein sequences were used to compare divergence and construct phylogenetic trees for the genus Alphavirus. Tree topologies indicated that the mosquito-borne alphaviruses could have arisen in either the Old or the New World, with at least two transoceanic introductions to account for their current distribution. The tim...
متن کاملSystematics and evolution of ticks with a list of valid genus and species names.
In recent years there has been much progress in our understanding of the phylogeny and evolution of ticks, in particular the hard ticks (Ixodidae). Indeed, a consensus about the phylogeny of the hard ticks has emerged which is quite different to the working hypothesis of 10 years ago. So that the classification reflects our knowledge of ticks, several changes to the nomenclature of ticks are im...
متن کاملRelationships between Tobacco Mosaic Virus and the Non-virus Proteins
1. The non-virus proteins, A4, B3, and B6, characteristically found in tobacco leaf infected with TMV exhibit specific immunochemical cross-reactions with serum prepared against the virus. The close immunochemical relations which occur among these proteins do not extend to any normal tobacco leaf proteins. 2. The rate of appearance of the non-virus proteins in newly infected cultured leaf tissu...
متن کاملHost-virus relationships in virus-induced tumors and transformed cells.
Dr. Rauscher has presented results of the work of Henle and Henle (16) with the EB2 cells derived from Burkitt lymphoma, stating that interferon is produced by these cells. This may sug gest that a viral agent is carried by these cells, and obviously this is a promising lead in attempting to establish an etiologic factor. Several points seem pertinent concerning inteiferon production, and these...
متن کاملMolecular systematics of Eumolpinae and the relationships with Spilopyrinae (Coleoptera, Chrysomelidae).
The 3400 species of Eumolpinae constitute one of the largest subfamilies of leaf beetles (Chrysomelidae). Their systematics is still largely based on late 19th century monographs and remains highly unsatisfactory. Only recently, some plesiomorphic lineages have been split out as separate subfamilies, including the southern hemisphere Spilopyrinae and the ambiguously placed Synetinae. Here we pr...
