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 کاملReplication and encapsidation of recombinant Turnip yellow mosaic virus RNA.
Turnip yellow mosaic virus (TYMV) is a positive strand RNA virus that infects mainly Cruciferae plants. In this study, the TYMV genome was modified by inserting an extra subgenomic RNA promoter and a multiple cloning site. This modified TYMV was introduced into Nicotiana benthamiana using a Agrobacterium-mediated T-DNA transfer system (agroinfiltration). When a gene encoding beta-glucuronidase ...
متن کاملSpermidine, an intrinsic component of turnip yellow mosaic virus.
The major polyamine of turnip yellow mosaic virus has been identified as spermidine by gas chromatography and mass spectrometry of the trifluoroacetamido derivative. Very small amounts of putrescine and cadaverine, but not norspermidine, have been detected in the virus. The spermidine contents of numerous virus preparations were in the range 200-700 molecules per virion and were considerably in...
متن کاملIdentification and Molecular Characterization of the Chloroplast Targeting Domain of Turnip yellow mosaic virus Replication Proteins
Turnip yellow mosaic virus (TYMV) is a positive-strand RNA virus infecting plants. The TYMV 140K replication protein is a key organizer of viral replication complex (VRC) assembly, being responsible for recruitment of the viral polymerase and for targeting the VRCs to the chloroplast envelope where viral replication takes place. However, the structural requirements determining the subcellular l...
متن کاملSerological Interrelationships in the Turnip Yellow Mosaic Virus Group .--I
The serological interrelationships between eleven viruses in the turnip yellow mosaic virus group (tymoviruses) were studied with 2% antisera from 48 rabbits. Antisera from different rabbits and from different bleedings of the same rabbit showed considerable differences in their homologous and heterologous reactivities. A classification based on average serological differentiation indices is pr...
