    植物源抗烟草花叶病毒天然产物研究进展

    Advance in Natural Products from Plants with Anti-TMV Activity

    • 摘要: 烟草普通花叶病毒病(TMV)是严重影响烟叶产量和质量的一种病害。综述了植物源活性天然产物抗烟草花叶病毒的研究、应用现状及作用机理。抗烟草花叶病毒的植物源天然产物主要包括大分子和小分子两大类,它们抗植物病毒的机理主要包括抑制病毒侵染、干扰和抑制病毒增殖、诱导植物抗病性反应等。讨论了植物源天然产物抗植物病毒开发和利用研究中面临的困境与挑战。

       

      Abstract: Tobacco mosaic virus (TMV) is a kind of plant disease, which severely affect the yield and quality of flue-cured tobacco. In this paper, the recent anti-TMV research, application and mechanism of the bioactive natural compounds from plants were reviewed. Natural compounds from high plants with anti-TMV activity mainly include macro-molecular and micro-molecular substances. Antiviral function of these bioactive compounds has multiple aspects, including defending against viral infection, inhibitory and interference activity of virus multiplication and inducing resistance activity of plant. Finally, the difficulties and challenges in development and utilization of natural products from plants with resistance to plant virus were discussed.
