Rice black-streaked dwarf disease, caused by Rice black-streaked dwarf virus (RBSDV) transmitted by the small brown planthopper (SBPH, Laodephax striatellus Fallén), is a serious threat to rice production.In our study, an RBSDV-resistant variety Tetep from Vietnam was screened by the field test and verified by the artificial inoculation test.The result of SBPH and RBSDV resistance evaluation revealed rice black-streaked dwarf disease resistance of Tetep derived from resistance to RBSDV rather than SBPH.Inheritance analysis and QTL mapping were carried out using F2populations derived from the cross between Huaidao No.5 and Tetep.

香蕉束顶病毒(banana bunchy top virus,BBTV)是引起香蕉病毒病的主要病害之一,属矮缩病毒科(Nanaviridae)香蕉束顶病毒属(Babuvirus)成员.其基因组由至少6个环状ssDNA组份组成,分别标记为1、2、3、4、5、6,每一组份大小均为1.0～1.1kb.DNA1、DNA2、DNA3、DNA4、DNA5、DNA6分别编码不同功能的病毒蛋白,分别是复制蛋白酶(
杆状DNA病毒(Badnavirus)属于花椰菜花叶病毒科(Caulimoviridae),病毒核酸为环状双链DNA(double-stranded DNA,dsDNA).该类病毒可侵染香蕉、甘蔗、柑橘、芋头、可可树、薯蓣等多种热带、亚热带经济作物,引起黄化、褪绿斑驳、叶缘卷曲、脉明、脉坏死、肿瘤、叶斑等症状.杆状DNA病毒属成员主要由带毒寄主植物的无性繁殖材料传播,自然界中多数种由昆虫介体粉蚧以
兰花是花卉产业最重要的观赏植物之一,近年来,随着兰花产业的迅速发展,兰花国际国内贸易和种质交流都十分频繁,一旦感染病毒,兰花的观赏价值和经济价值将受严重影响.建兰花叶病毒(cymbidium mosaic virus,CymMV)和齿兰环斑病毒(odontoglossum ringspot virus,ORSV)是为害兰花的两种主要病毒,建立这两种病毒高效检测方法对兰花生产有重要意义.本研究建立了
本研究从受感染的草莓植株中提取了草莓镶脉病毒(SVBV)粒子并对其进行了电镜观察.首先，用CTAB法从草莓叶片中提取总核酸，设计SVBV外壳蛋白基因特异性引物，利用PCR方法对杭州地区的草莓镶脉病毒感染情况进行检测.检测结果表明，在杭州地区大田种植的草莓中存在SVBV感染现象.从4株受感染草莓植株中分离克隆了SVBV的CP基因片段并测序；序列比较分析发现它们与已报道的美国SVBV分离物的CP基因(
