Abstract
The mol. wt. of the DNA from four nuclear polyhedrosis viruses isolated from Spodoptera littoralis, S. exempta, S. exigua and S. frugiperda were determined to be 84, 80, 68 and 74 X 10(6), respectively, by electron microscopy. The molecules were demonstrated to exist as double-stranded relaxed circular or supercoiled DNA, though linear forms of DNA were also observed.
摘要
通过电子显微镜测定，从埃及棉铃虫、草地贪夜蛾、甜菜夜蛾和玉米螟中分离出的四种核型多角体病毒的DNA分子量分别为84×10⁶、80×10⁶、68×10⁶和74×10⁶。这些分子被证明以双链松弛环状或超螺旋DNA的形式存在，不过也观察到了线性DNA形式。
