Abstract

SUMMARY: Electron micrographs of potato virus , show tenuous rod-shaped particles of variable length but constant width of about 10 m. Lightly shadowed rods lying along the direction of shadowing show a regular cross banding at intervals of about 10 m. Attempts to purify the virus cause the particles to aggregate and become entwined to form extensive rope- and net-like structures. This aggregation may be responsible for the loss of solubility that often accompanies purification, though similar structures are visible in micrographs of both soluble and insoluble preparations of the purified virus. Hydrolysis by chymotrypsin yields products too small to be resolvable, and the material remaining after most of a preparation has been hydrolysed appears similar to that in unincubated preparations.
