Galinsoga mosaic virus

Electron micrograph of a thin section of an infected leaf cell of P. vulgaris showing the characteristic multivesicular bodies and vesicles associated with the chloroplast membrane (arrows). Insert shows vesicles at the outer membrane of a multivesicular body. Sections were prepared from tissues fixed with aldehyde and treated with ribonuclease to remove ribosomal RNA, a process which leaves the virus particles unaffected (Hatta & Francki, 1981). Bars represent 200 nm.
