Abstract
Using analytical and preparative methods, we demonstrated the presence of megaplasmids with molecular weight larger than 450 x 10(6) in the two plant-associated bacteria Rhizobium meliloti and Pseudomonas solanacearum. Such giant plasmids were found in 8 of 9 P. solanacearum strains tested and in all of the 18 R. meliloti strains tested.
摘要
通过分析和制备方法，我们证明了在两种与植物相关的细菌——苜蓿根瘤菌和青枯雷尔氏菌中存在分子量大于450×10⁶ 的大质粒。在所测试的9株青枯雷尔氏菌菌株中有8株以及在所测试的18株苜蓿根瘤菌菌株中均发现了这种巨型质粒。
