Molecular genetics of vaccinia virus: demonstration of marker rescue.
Two genomic variants of vaccinia virus isolated from serially propagated stocks were used to demonstrate marker rescue. The smaller (S variant) virus contains a 6.3 megadalton (MDal) deletion of unique DNA sequences present in the 123-MDal larger (L variant) virus. The deletion was mapped at 6.85 MDal from the left terminus of the genome, just outside of the inverted terminal repetition. Rescue...
متن کاملMarker rescue of temperature-sensitive mutations of vaccinia virus WR: correlation of genetic and physical maps.
The physical map locations of 62 temperature-sensitive mutations of vaccinia virus WR have been determined by marker rescue experiments, using cloned HindIII fragments of wild-type DNA. Since vaccinia virus DNA is not infectious, marker rescue was performed by infecting monolayers of cells at the nonpermissive temperature with a low multiplicity of the mutant to be rescued and transfecting with...
متن کاملMolecular Genetics and Epidemiology of Vitiligo
Background: Vitiligo is an acquired, idiopathic, and common depigmentation disorder of the skin that affects people of all ages and both sexes equally in the worldwide. Although etiology of the disease is unknown, there are theories such as environment and genetic factors. Methods: In this article, we collected and summarized the appropriate manuscripts regarding the epidemiology and gene...
متن کاملPneumoviruses: Molecular Genetics and Reverse Genetics
Pneumoviruses are responsible for significant respiratory disease in their hosts and represent a major problemfor human and animal health. Pneumoviruses are members of the family Paramyxoviridae, subfamilyPneumovirinae and the virus particles consist of a negative-sense, nonsegmented RNA genome within a helical nucleocapsid structure enveloped in a lipid membrane derived from the ho...
متن کاملMapping of the vaccinia virus DNA polymerase gene by marker rescue and cell-free translation of selected RNA.
The previous demonstration that a phosphonoacetate (PAA)-resistant (PAAr) vaccinia virus mutant synthesized an altered DNA polymerase provided the key to mapping this gene. Marker rescue was performed in cells infected with wild-type PAA-sensitive (PAAs) vaccinia by transfecting with calcium phosphate-precipitated DNA from a PAAr mutant virus. Formation of PAAr recombinants was measured by plaq...
