X-ray fiber diffraction data were obtained and helical pitch and symmetry were determined for seven members of the family Potyviridae, including representatives from the genera Potyvirus, Rymovirus, and Tritimovirus. The diffraction patterns are similar, as expected. There are, however, significant variations in the symmetries, as previously found among the flexible potexviruses, but not among the rigid tobamoviruses. Wheat streak mosaic virus, the only member of the genus Tritimovirus examined, displayed the largest deviations in diffraction data and helical parameters from the other viruses in the group.
