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 کاملGenetic control of broad-spectrum resistance to turnip mosaic virus in Brassica rapa (Chinese cabbage).
The Brassica rapa line RLR22 was resistant to eight diverse turnip mosaic virus (TuMV) isolates. A B. rapa genetic map based on 213 marker loci segregating in 120 first back-cross (B(1)) individuals was established and aligned with the B. rapa genome reference map using some of the RFLP probes. B(1) individuals were self-pollinated to produce B(1)S(1) families. The existence of two loci control...
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...

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...
