摘要
为明确甜菜生尾孢Cercospora beticola中真菌病毒的多样性,2020年自新疆维吾尔自治区、内蒙古自治区、黑龙江省和北京市采集感染褐斑病甜菜病叶,鉴定获得78株甜菜生尾孢菌株,运用高通量的宏转录组测序技术检测甜菜生尾孢所携带的真菌病毒种类;将分离到的甜菜生尾孢按照菌落生长表型分为4组,进行宏转录组测序,将得到的序列经过拼接、聚类和基因功能注释,筛选出真菌病毒相关同源序列。序列分析结果显示,4组样品共比对到6个真菌病毒科,包括双分体病毒科Partitiviridae、双核糖核酸病毒科Birnaviridae、低毒病毒科Hypoviridae、裸露RNA病毒科Narnaviridae、泛欧尔密病毒科Botourmiaviridae和转座病毒科Metaviridae,以及未分科的负义单链RNA病毒。研究结果丰富了甜菜生尾孢真菌病毒资源库。
To explore the diversity of mycoviruses associated with the plant pathogenic fungus Cercospora beticola,78 single-spore isolates of C.beticola collected from several fields in Xinjiang Uygur Autonomous Region,Inner Mongolia Autonomous Region,Heilongjiang Province and Beijing City in 2020 were used for metatranscriptome sequencing analysis.Isolates were divided into four groups based on different colony phenotype and sequenced with high-throughput sequencing.Raw data were transcribed,clustered and functionally annotated.A total number of six virus families and a few unclassified(-)ssRNA viruses were identified according to the bioinformatics analysis.The identified fungi-associated viruses belong to Partitiviridae,Birnaviridae,Hypoviridae,Narnaviridae,Botourmiaviridae and Metaviridae.This study enriched the mycoviruses resource of C.beticola.
