中国水稻矮化类病毒病的研究进展

Progress in Study of Dwarf-like Disease of Oryza sativa L.in China

摘要: 水稻矮化类病毒病是我国水稻常见的病毒病之一,近年来,在我国十几个省市都有普遍发生,且有逐年上升的趋势。就水稻矮化类病毒病发病概况、分类、发病症状、传播途径及发病机理等方面进行了概述,简要介绍了水稻矮化类病毒基因组研究的情况,并较为详细地介绍了水稻矮化类病毒病抗病材料的筛选、抗性基因定位及克隆等方面的研究进展。系统地分析了当前水稻矮化类病毒病研究中存在的问题,并就今后如何进一步深入开展水稻矮化类病毒病的研究进行了展望。

Abstract: Rice dwarf-like disease is one of the common viral diseases of rice.In recent years,rice dwarf-like disease occurs frequently in several provinces in China with a rising trend.This paper reviews the rice dwarf-like disease’s situation,classification,symptoms,transmission route and pathogenesis,followed by its genome study.In addition,the screening of resistant material,the resistant gene mapping and cloning,as well as the existing problems are discussed.Future expectation on the related research and new areas for studies on the rice dwarf-like disease are also included.
