SUMMARY
An electron microscopic study was made on sweet potato (Ipomoea batatas L.) leaf tissues infected by sweet potato mosaic virus (SPMV), an elongated (15nm x 850nm) virus, considered as a member of the potato virus Y (PVY) group. This last assumption was further stressed by the consistent presence of lamellar inclusions, with varied configuration depending on the plane of the section, in the infected cells. Such inclusions have been considered as typical for infection by viruses of the PVY group.
Besides these lamellae, elongated particles, probably representing SPMV in situ were occasionally found, forming loose aggregates, or closely apposed to the tonoplast. In a few instances, masses of a dense material, resolved as a bundle of fine fibrils, interspersed with an amorphous substance, were seen in th cytoplasm.
