Wheat powdery mildew,caused by the fungal pathogen Blumeria graminis f.sp.tritici (Bgt),is a destructive wheat disease worldwide.The key issue of the disease forecast is to timely and accurately estimate and quantify the latent infection levels in volunteer seedlings where the pathogen overwinters or oversummers to serve as sources of initial inoculum of epidemics.

A disease ofmango(Mangifera indica)observed in 2009～2010 in Hainan and Guangxi provinces (China) is characterized by small water-soaked spots on the leaves turning with age into angular, sunken, deep-
Maize rough dwarf (MRDD) , rice black-streaked dwarf (RBSDD) , rice stripe diseases (RSD) are serious viral diseases transmitted by small brown planthopper (SBPH) (Laodelphax striatellus).Once occurre
泡桐丛枝病是最早发现由植原体引起的病害之一，植原体是寄生于植物韧皮部筛管细胞缺乏细胞壁的原核微生物。构建泡桐cDNA文库，把含有泡桐cDNA文库的酵母菌AH109与含有诱饵载体pGBKT7P19的酵母菌Y187进行交配，把交配后的菌液直接涂布到SD/-Ade/-His/-Leu/-Trp四缺培养基上进行筛选。通过两轮四缺培养基筛选和a-X-半乳糖苷酶活性检测，从酵母双杂交的主板上共挑取8个阳性菌落
核盘菌是重要的世界性分布的植物病原真菌，寻找和筛选核盘菌病毒，可以为作物菌核病的生物防治提供有益病毒资源。从油菜罹病残体的菌核上分离获得了称为SN21-3-5的菌株。将菌株Ep-1PNA367和SN21-3-5分别接种离体的油菜叶片，菌株Ep-1PNA367于48hpi时病斑直径平均约为3.2cm/d;菌株SN21-3-5平均约为1.5cm/d。在SN21-3-5菌株中检测到2条dsRNA片段，大

病毒病害的发生严重影响了瓜类作物的产量和品质。在我国存在3种侵染瓜类的马铃薯卷叶病毒属病毒，分别是南瓜蚜传黄化病毒（CABYV）、甜瓜蚜传黄化病毒(MABYv)和丝瓜蚜传黄化病毒(SABYV)。本文就3种病毒的多重RT-PCR检测技术进行了研究，利用序列分析软件分析国外报道的和本实验室已经获得的CABYV、MABYV和SABYV序列，由于病毒难于提纯，因此用带有T7 RNA启动子的3种病毒的部分片
采用室内接种鉴定法从20份小麦近缘属种材料中筛选出对菲利普胞囊线虫具有较好抗性的簇毛麦,相对抗病指数RI达到0.99,属于高抗材料.对中国春-二倍体簇毛麦整套异附加系(Add1V～7V)进行室内接种菲利普胞囊线虫抗病性鉴定,发现Add6r抗性明显异于其他异附加系材料,达到高抗水平.进一步对含有6VS(第6条染色体短臂)的易位系材料进行抗菲利普胞囊线虫鉴定,结果显示均达到了高感水平.由此,本研究初步
