甜菜坏死黄脉病毒不同分离物外壳蛋白的研究

Studies on Differentiation of Coat Protein of BNYVV Isolates from Xinjiang

应用SDS PAGE和PCR SSCP分析技术,对新疆不同地区的BNYVV分离物进行分析,结果表明:12个分离物蛋白质外壳的蛋白亚基分子量均为20kD;来自库尔勒的K4和K5分离物编码外壳蛋白质的基因不同于其他地区和本地区的分离物,二者彼此间也不相同。

12 Beet necrotic yellow vein virus (BNYVV) isolates from different beet production regions were analyzed by SDSpolyarch gel electron and PCRSSCP.The results showed that the molecular of coat protein subunit of all isolates were 20 kD,the gene of coat protein from Kurle isolates K4 and K5 were different from other isolates. There were some differences between K4 and K5.
