稻瘟病菌真菌病毒的研究进展

Research Progress on Mycoviruses of Magnaporthe oryzae

稻瘟病是由稻巨座壳菌(Magnaporthe oryzae,俗称稻瘟病菌)引起的一种世界性的重要水稻病害,也是影响水稻产量和品质的重要因素。真菌病毒是指侵染真菌或卵菌并能够在其体内进行增殖的病毒,广泛存在于真菌和卵菌的主要类群中,某些低毒真菌病毒可作为植物真菌病害生物防治的资源。笔者描述了稻瘟病菌中已报道的真菌病毒的形态、基因组结构及其对寄主真菌的影响,并对稻瘟病菌真菌病毒的研究进行了展望,旨在对稻瘟病菌真菌病毒有一个较全面的了解和认识,为稻瘟病菌真菌病毒的利用和深入研究提供参考。

Rice blast is an important worldwide important rice disease caused by Magnaporthe oryzae(commonly known as rice blast fungus),and it is also an important factor affecting rice yield and quality.Mycovirus is a virus that infects fungi and oomycetes and can replicate in them,which is widespread in the major taxa of fungi and oomycetes.Some hypovirulent mycoviruses can be used as resources for the biological control of plant fungal diseases.The mycoviruses reported in M.oryzae,including their morphological,genome organization and their effects on host fungi,were reviewed,and the research on the mycoviruses of M.oryzae was prospected so as to have a more comprehensive understanding of mycoviruses in M.oryzae,and to provide reference for the utilization and study of mycoviruses in M.oryzae in the future.
