烟粉虱基因组和转录组研究及展望

The progress of genome and transcriptome analysis of Bemisia tabaci and its future perspectives

烟粉虱Bemisia tabaci(Gennadius)是世界性的重要害虫,为物种复合体,其中少数隐种近30年来入侵世界各国,并暴发成灾。在我国,最近几年MED隐种已经逐渐替代了之前入侵的MEAM1隐种,成为我国农田生态系统中的主要致害隐种。基因组和转录组研究的不断深入极大地推动了烟粉虱入侵机制、隐种替代机制、种系发生、不同隐种或地理种群鉴定、抗药性机制、烟粉虱与共生菌互作等领域的研究。本文简要综述了烟粉虱基因组和转录组测序的研究进展,介绍了转录组数据在种的分化和鉴定、共生菌的互作及抗药性研究领域的应用。

The tobacco whitefly,Bemisia tabaci（ Gennadius）,is a worldwide distributed agricultural pest,which is considered as a complex species. Some cryptic species have invaded many countries in the last three decades,causing huge economic and yield loss in agriculture. Mediterranean cryptic species（ MED） entered into China and has replaced middle East-Asia minor 1 cryptic species（ MEAM1）.Genome and transcriptome analysis would greatly facilitate the researches on invasion mechanism,species complex,identification of cryptic species or geographical population,insecticide resistance mechanism,interaction between host and endosymbiont. Here,the progress of genome and transcriptome researches of B. tabaci were briefly summarized. The applications and future perspectives of omics studies in the whitefly field were also presented.
