DNA Synthesis in Tobacco Mosaic Virus-Infected Nicotiana tabacum Protoplasts and Regeneration of Persistently Infected Calli

摘要

>Tobacco mosaic virus infection of Nicotiana tabacum mesophyll protoplasts did not affect the pattern of chloroplast or total cellular DNA synthesis for at least 120 h when compared with that of mock-infected cells. Calli derived from infected protoplasts often showed large amounts of tobacco mosaic virus RNA and coat protein.
