• Strips of epidermal tissue bearing hair cells were removed from tomato stems. The lower surface exposed by the stripping was inoculated with tobacco mosaic virus and the progress of infection of the hair cells was followed microscopically and by extraction of infectivity. Shortly before infectivity could be extracted from the hair cells, the nuclei were observed to have migrated towards the transverse wall of the basal hair cell nearest the epidermis, apparently the site at which infection of the cell commences. After infection was apparent, the staining characteristics of the nuclei, before and after RNase and DNase treatment, suggested an accumulation of RNA. A granular body, different from X-bodies maintained a close association with the nucleus of TMV infected hair cells, and was found to be rich in RNA, suggesting that viral RNA of the nucleus may have been entering the cytoplasm via the granular body. A possible mechanism of X-body formation arising from the granular body is suggested.
