RNA silencing plays important roles in defense against invading virus in plants.Virus-derived small interfering RNAs (vsiRNAs) can inactivate the viral genome and may target host mRNAs.Rice black-streaked dwarf virus (RBSDV) is transmitted to plant species by the small brown planthopper (SBPH), which severely affects rice and maize production in East Asia in recent years.VsiRNAs produced from their insect vectors are well described but those from their hosts are less characterized.Through deep sequencing, we examined vsiRNAs from infected leaves and shoots of RBSDV-infected two rice genotypes—japonica and indica.To our data, vsiRNAs identified in both genotypes were distributed along the whole genome of RBSDV.More vsiRNAs were derived from the positive strands and mostly were 21 ~ 22nt long.

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(
