A UV-sensitive derivative was obtained from Streptococcus sanguis Challis. The organism could be transformed with a number of small streptococcal plasmids at frequencies equal to, or 1 logarithm below, the transformation frequencies for the parent organism. However, transformation with chromosomal DNA was greatly impaired in the UV-sensitive derivative.
从血链球菌查利斯菌株中获得了一种对紫外线敏感的衍生物。该菌株能够被多种小的链球菌质粒转化,其转化频率与亲代菌株相同,或比亲代菌株低1个对数。然而,在紫外线敏感的衍生物中,用染色体DNA进行的转化受到极大损害。
