A series of isogenic transformable strains of Bacillus subtilis carrying the uvr-19 or rec-43 mutation or both were constructed. Both mutations made competent cells defective in repairing UV-irradiated cellular or transforming DNA, and their effects were additive in a doubly deficient strain, suggesting that two repair processes, requiring uvr-19+ and rec-43+ gene products, are independently functional in competent cells of B. subtilis.
构建了一系列携带uvr - 19或rec - 43突变或两者都携带的枯草芽孢杆菌同基因可转化菌株。这两种突变均使感受态细胞在修复紫外线照射的细胞DNA或转化DNA方面存在缺陷,并且它们在双倍缺陷菌株中的作用是累加的,这表明需要uvr - 19 +和rec - 43 +基因产物的两个修复过程在枯草芽孢杆菌的感受态细胞中是独立发挥功能的。
