Equilibrium sedimentation of turnip yellow mosaic virus.
Sedimentation equilibrium was achieved with turnip yellow mosaic virus at low speeds (600 rpm) in a magnetic ultracentrifuge. The experiments were carried out in the newly installed constant-speed rotor, equipped with automatic control and an electromagnetic drive. A particle mass of 5.55 x 10(6) daltons was calculated for the virus at vanishing concentrations, in essential agreement with the e...
متن کاملEvolutionary trajectory of turnip mosaic virus populations adapting to a new host.
Little is known about how some plant viruses establish successful cross-species transmission whilst others do not; the genetic basis for adaptation is largely unknown. This study investigated the genetic changes that occurred using the progeny of an infectious clone, p35Tunos, derived from the turnip mosaic virus (TuMV) UK 1 isolate, which has a Brassica host type, but rarely infects Raphanus s...
متن کاملMolecular evolution of Turnip mosaic virus: evidence of host adaptation, genetic recombination and geographical spread.
Turnip mosaic virus (TuMV), a species of the genus Potyvirus, occurs worldwide. Seventy-six isolates of TuMV were collected from around the world, mostly from Brassica and Raphanus crops, but also from several non-brassica species. Host tests grouped the isolates into one or other of two pathotypes; Brassica (B) and Brassica-Raphanus (BR). The nucleotide sequences of the first protein (P1) and ...
متن کاملContribution of Host Intracellular Transport Machineries to Intercellular Movement of Turnip Mosaic Virus
The contribution of different host cell transport systems in the intercellular movement of turnip mosaic virus (TuMV) was investigated. To discriminate between primary infections and secondary infections associated with the virus intercellular movement, a gene cassette expressing GFP-HDEL was inserted adjacent to a TuMV infectious cassette expressing 6K₂:mCherry, both within the T-DNA borders o...
متن کاملMutational bias of Turnip Yellow Mosaic Virus in the context of host anti-viral gene silencing.
Plant Dicer-like (DCL) enzymes exhibit a GC-preference during anti-viral post-transcriptional gene silencing (PTGS), delivering an evolutionary selection pressure resulting in plant viruses with GC-poor genomes. However, some viruses, e.g. Turnip Yellow Mosaic Virus (TYMV, genus Tymovirus) have GC-rich genomes, raising the question as to whether or not DCL derived selection pressure affects the...
