Abstract

Summary

Attempts were made to determine more precisely the structure and properties of a closterovirus, beet yellows virus (BYV), and a luteovirus, beet mild yellowing virus (BMYV), by scanning transmission electron microscopy, optical diffraction of electron images and acrylamide gel electrophoresis. It was shown that BYV has a mol. wt. of 76.5 × 10, including an RNA of 4.15 × 10. The pitch of the helix is 3.7 nm and there would be 8.5 protein subunits per turn. BMYV particles have a diameter of 26 nm and a total mol. wt. of 6.5(±0.45) × 10. The mol. wt. of the protein subunit is about 24000 and that of the RNA 2 × 10.
