总结：之前两次对菜豆花叶病毒相关DNA β卫星多样性的分析主要集中在来自印度次大陆和中国南部的分子上。他们根据分离出的寄主（锦葵科或非锦葵科植物）将卫星进行分组，然后根据地理来源和寄主形成亚组。本研究分析了东亚和东南亚地区DNA β卫星的多样性。这里的卫星按地理位置分组，比以前指出的要多样化得多。这可能反映了菜豆病毒/DNA β复合物在该区域的有限移动以及它们随后从一个共同祖先到各种宿主的多样化。
Summary.Two previous analyses of the diversity of begomovirus-associated DNA β satellites focused predominantly on molecules originating from the Indian sub-continent and southern China. They showed the satellites to group according to the hosts from which they were isolated, either malvaceous or non-malvaceous plants, and then to form sub-groups based upon geographic origin and host. In this study we analysed the diversity of DNA β satellites in east and south east Asia. Here the satellites group by geographic location and are considerably more diverse than previously indicated. This probably reflects the limited movement of begomovirus/DNA β complexes in this region and their subsequent diversification from a common ancestor to a variety of hosts.
