Pre-mRNA splicing is an important gene expression regulation mechanism in eukaryotic cells.The PRP4 gene encode the only protein kinase involved in pre-mRNA plicing.In the fission yeast and mammals, it is an essential gene but the budding yeast lacks a distince Prp4 ortholog which has limited number of small introns.

从红树林中分离出的一株芽孢杆菌HD34,在平板对峙实验中,对香蕉枯萎病4号生理小种产生很强的拮抗作用。通过形态学鉴定、生理生化实验及16S rDNA的分子生物学等方法,对产拮抗物质的HD34菌株进行了分类学鉴定,最终确定菌株HD34为解淀粉芽孢杆菌,并将其命名为解淀粉芽孢杆菌HD34(Bacillus amyloliquefaciens HD34)。对HD34发酵液通过高温80℃水浴20min,蛋
豌豆细菌性疫病菌(Pseudomonas syringae pv.pisi,PSPI)和菜豆晕疫病菌(Pseudomonas syringae pv.phaseolicola,PSPHA)均属于我国进境植物检疫性有害生物,主要通过种子携带进行远距离传播,为害豆科作物并可造成重大的经济损失.目前预防控制上述两种病害最有效方法是进行种子检疫并种植无携带病菌的种子.本研究根据gyrB基因序列分别设计了P
针对赣南脐橙有典型黄龙病病果未见典型斑驳叶片的情况,选择引物A2/J5和引物Las606/LSS分别运用PCR方法检测柑橘黄龙病,表明黄龙病菌在病树体内分布无规律,比较了柑橘黄龙病菌的5对检测引物的灵敏度,Las606/LSS有较高的灵敏度和稳定性。
白粉病是橡胶树主要的叶部病害之一，对我国橡胶种植产业的危害严重.尽管在橡胶生产上白粉病得以控制，但由于对白粉菌侵染后生理响应机制和橡胶树抗病机制缺乏研究，白粉病防治仍以化学防治为主，导致一方面白粉菌对药剂很快产生抗药性而造成防治失效，另一方面缺乏高抗白粉菌橡胶树品系，这是目前白粉病防治存在的主要问题.Mlo基因是白粉病广谱抗性基因，调控多种植物的白粉病抗性，其抗性已在大麦、拟南芥等多种单子叶和双子
木霉属(Trichoderma spp.)真菌是一类重要的植物有益真菌,对许多种植物病原真菌有防治效果,并且可以促进植物生长.一些木霉种类如哈茨木霉(T.harzianum)和绿色木霉(T.viride)等已用于在植物病害中.我们自土壤中分离到拟康宁木霉(T.koningiopsis)菌株T-51,对其防治番茄灰霉病及促进番茄生长的效果进行了研究.
根据近年来水稻稻瘟病发生情况及其化学防治研究现状,本文对6种药剂防治水稻稻瘟病进行了田间药效试验.试验结果表明,250g/L嘧菌酯SC与125g/L氟环唑SC混用防治效果最优,对叶瘟和穗瘟的防效均达80％以上；250g/L嘧菌酯SC和125g/L氟环唑SC单剂对叶瘟和穗瘟的防效均在75％以上；30％苯醚甲环唑SC对叶瘟和穗瘟的仿效分别为77.47％和72.93％；40％稻瘟灵WP和20％三环唑WP
