Antiviral activity of natural and recombinant human leukocyte interferons in tobacco protoplasts.

abstract：:Published ultraviolet (uv) inactivation data and in vitro transcription studies have suggested that vesicular stomatitis virus (VSV) leader RNA was solely responsible for the inhibition of host cell RNA synthesis by this virus. Since no protein product is encoded in leader RNA, this conclusion implied that no protein ...
