中国水稻条纹叶枯病研究进展

Research advances in rice stripe disease in China

水稻条纹叶枯病是水稻重要的病毒病害,对水稻生产造成了极大损失。该病是由灰飞虱(LaodelphaxStriatellus Fallén)传播水稻条纹病毒(Rice stripe virus,RSV)引起的。该文综述了近年来国内外有关水稻条纹病毒的基因组结构、功能、复制、表达调控、分子变异、病毒与介体互作、抗病育种、预测预报和防治等方面的最新研究进展,并进行了讨论和展望。

Rice stripe disease is a significant virus disease in rice plants,which was reported to have caused severe yield losses in recent years.The pathogen,rice stripe virus（RSV）,is known to be transmitted mainly by the small brown planthopper（Laodelphax striatellus Fallén,SBPH）.In this paper,the genome organization,function,replication,gene expression and regulation,molecular variability,interactions between virus and vector,resistance breeding of RSV,as well as forecast and control of the disease were reviewed.Meanwhile,researches on RSV was prospected.
