Different components of the two BMV strains-RNA are isolated by meansof two phases phenol method in the presence of bentonite and SDS. Theresults of polyacrylamide gel electrophoresis of BMV-RNAs further confirmthat BMV-G has a new component RNA3a.

• 对用两相酚法提取的雀麦花叶病毒E株系和G株系的RNAs进行了聚丙烯酰胺凝胶电泳,其结果进一步证明RNA3a是BMVG株系中的一个新RNA组份。
