新疆地域广阔,各地气候条件差异大。西瓜、甜瓜在新疆种植面积较广,其病毒病的发生和危害较重。西瓜花叶病毒2号(Watermelon mosaic vi-rus2,WMV-2)是致病的主要毒源之一。前人对WMV-2的研究仅限于病原鉴定以及它对瓜类氨基酸的影响,而对它的遗传变异未做研究。为了深入研究新疆不同地域WMV-2致病性的差异,有必要弄清楚新疆的WMV-2有无遗传变异的发生。PCR-SSCP是一种基于PCR的单链构象多态性
Xinjiang has a vast territory and varies greatly in climatic conditions. Watermelon, melon in Xinjiang planting a wider area, the occurrence of the virus and the damage is more serious. Watermelon mosaic vi-rus2 (WMV-2) is one of the main pathogenic pathogens. Previous studies of WMV-2 were limited to the identification of pathogen and its effect on melons amino acids, but no study on its genetic variation. In order to further study the difference of pathogenicity of WMV-2 in different regions of Xinjiang, it is necessary to find out whether there is genetic variation of WMV-2 in Xinjiang. PCR-SSCP is a PCR-based single-strand conformation polymorphism
