　　苹果煤污病(sooty blotch and flyspeck)症状有多种类型,其中蝇粪型主要由接瓶霉属(Zygophiala)真菌引起.目前国外报道的接瓶霉属真菌共5 个种.本研究对我国苹果主产区及其它各地表现蝇粪症状的寄主进行广泛采集,共采集样品500 余份,分离获得66 株接瓶霉,通过形态学及多基因(ITS,TEF,TUB,ACT)分子生物学鉴定,共鉴定出10 种接甁霉属真菌,其中8 种为新种,6 种可以在苹果果实上.Z.wisconsinensis和 Z.emperorae 为优势种.致病性测定显示Z.longispora(分离于香蕉果实)可以侵染苹果.表明其为苹果潜在的侵染来源.

菌丝际土壤有机磷周转的微生物调控机制

AM 真菌与细菌都是微生物中的重要功能组群，在土壤磷循环中发挥着至关重要的作用，而且两者之间的相互作用也有利于土壤磷的周转和植物磷养分的吸收，但其互作机理及其对土壤磷周转与利用的生态功能的研究还很薄弱。
