Wheat stripe rust is one of the most destructive diseases of wheat worldwide.It causes huge yield losses every year in China and many other countries.Puccinia striiformis f.sp.tritici (Pst),the causal fungus of wheat stripe rust, was previously reported to be infected by Fusarium nivale, Typhula idahoensis, and Verticillium lecanii.Here, we report a novel hyperparasite on Pst.This hyperparasitic fungus was identified as Cladosporium cladosporioides (Fresen.) GA de Vries based on the morphological characteristics determined under both an optical and an electron microscope, together with three genes (ACT, EF1-α, and ITS) sequencing analysis of the fungal strain.The hyperparasite was capable to reduce the viability of urediospores, and therefore could potentially be used for biological control of wheat stripe rust.

由灰葡萄孢(Botrytis cinerea)引起的灰霉病是一种世界性分布的重要植物病害，灰葡萄孢的寄主范围极其广泛，能侵染400多种植物，造成严重的经济损失。灰葡萄孢对寄主的致病作用是一个极其复杂的过程，多种致病因子参与其中，例如，细胞壁降解酶、毒素、抵抗寄主防卫反应的酶类及小分子物质。灰霉病的防治是农业生产上的难题之一，从分子水平上探究灰葡萄孢的致病机制可为灰霉病的防治奠定一定的基础。本研究主

病毒混合侵染现象在受真菌病毒感染的真菌中普遍存在,核盘菌中感染ssRNA病毒的菌株均是被病毒复合侵染.前期筛选获得核盘菌异常菌株PX14,该菌株产生黄色色素但不产菌核,其致病力呈现弱毒特性.提取dsRNA发现菌株PX14中至少含有7条dsRNA条带(按片段大小分别命名为dsRNA-A,B,As,C,D,E,F).采用常规克隆dsRNA的策略,获得了dsRNA-A的cDNA部分序列及dsRNA-B、
稻曲病菌[Ustilaginoidea virens (Cooke) Tak]引发的稻曲病是近年来在世界范围内广泛发生的水稻穗部真菌性病害,不仅降低稻谷产量,而且产生对人畜有害的稻曲毒素,稻曲毒素A (ustiloxin A)是其中主要的毒素成分.为了评估稻曲毒素A对稻米及饲料的污染程度,本实验以硝酸纤维素膜为载体,通过对Dot-ELISA法的包被条件、包被抗体浓度、点样量等反应条件进行优化,建立
本研究克隆稻曲病菌(Ustilaginoidea virens)分生孢子高产突变菌株A2588的T-DNA插入突变基因，解析该基因在稻曲病菌分生孢子形成中的功能，为进一步揭示稻曲病菌的分生孢子形成机制提供理论基础。研究通过测定A2588的产分生孢子能力、孢子萌发率、菌丝直线生长能力和热敏感性等生物学特性，利用hiTAIL-PCR、RACE和半定量PCR等方法克隆TDNA插入突变基因，并结合生物信息
