Release of viral transgenic plants to the environment: prospects and problems

摘要

Recent advances in the understanding of the molecular mechanisms of how viruses function and how they interact with plants have led to the development of non-conventional approaches to protection of plants against viruses. Many of these approaches, giving what is sometimes termed pathogen-derived protection, involve the introduction of viral or virus-based sequences into the plant's genome. Expression of these sequences then interferes with one or more of the viral functions, thus giving some protection against the virus.
