甘蔗線條花葉病毒RT-LAMP檢測方法的建立及應用(英文)
發(fā)布時間:2021-11-03 21:15
【目的】建立甘蔗線條花葉病毒(Sugarcane streak mosaic virus,SCSMV)的RT-LAMP檢測方法,為SCSMV的檢測提供技術支持。【方法】根據(jù)甘蔗線條花葉病毒外殼蛋白基因的保守序列設計特異引物,優(yōu)化RT-LAMP的反應條件,對比分析RT-LAMP的檢測靈敏度和特異性;并在RT-LAMP反應產(chǎn)物中加入SYBR GREEN I進行可視化檢測,方便快速判定結果。【結果】成功建立了一種用于檢測SCSMV的RT-LAMP方法,可在60 ~ 63 ℃下60 min完成對SCSMV的檢測,且具有較高的靈敏度,比傳統(tǒng)RT-PCR高100 倍,最低檢測RNA濃度為167.9×10-5 ng。此外,該方法具有較高的特異性,可特異檢測SCSMV!窘Y論】建立了一種靈敏、簡便、快速的SCSMV RT-LAMP檢測方法并用于田間甘蔗樣品的檢測。
