The phylogenetic analyses suggested that the YLS of BPH with different virulence belonged to the subphylum Ascornycotina, the class Pyrenomycetes, and had the closest genetic relationship with Hypomyces chrysospermus.

• 结果显示,褐飞虱3种不同致害性种群体内的YLS同属子囊菌亚门(Ascomycotina)的核菌纲(Pyrenomycetes),并与此纲中的Hypomyceschrysospermus亲缘关系相对最近。
