压砂甜瓜白粉病病原菌18S rDNA序列分析
Analysis of 18S rDNA Sequence of Melon Powdery Mildew from Lands Overlaid with Sands in Ningxia
摘要
Abstract
[Objective] The aim was to analyze the 18S rDNA sequence of melon powdery mildew from lands overlaid with sands. [Method] Thepathogen of melon powdery mildew was isolated from infected plants of "Yujinxiang" ,a major melon variety eultivated in lands overlaid with sandsof droughty midregion in Ningxia. Genome DNA was extracted from its conidia using Chelex-100 method. 18S rDNA sequence was amplified byPCR,which was analyzed by Blast after sequencing,and the phylogenetic tree was constructed. [ Result] 18S rDNA sequence analysis showed thatthe pathogen of melon powdery mildew belonged to Podosphaera. [Conclusion] The study provided reference for biocontrol and disease-resistancebreeding against melon powdery mildew.关键词
