Electron microscopy of thin sections of carnation (Dianthus caryophyllus L.) leaves, infected with carnation yellow fleck virus (CYFV), revealed CYFV particles in epidermis, ground parenchyma, and phloem and in mature xylem elements. Sections of CYFV aggregates revealed three distinctive characteristic patterns: (1) cross sections of hexagonal arrays with a center-to-center distance of 109 Å; (2) sections of nearly parallel virus particles; and (3) regions in which no orderly arrangement was evident. Tilting experiments showed that the different appearance of the sections was due only to their orientation and that the characteristic patterns are entirely interchangeable. The results of such tilting experiments lead us to suggest that in vivo the virus aggregates in a hexagonal array.
