Abstract

Progeny yields and the synthesis of nucleic acids have been investigated in two strains of Bacillus subtilis mixedly infected with two unrelated phages, SP82 and beta22. When B. subtilis strain 168 was the host, the first phage added dominated the infection; when B. subtilis strain SB11 was the host, beta22 produced progeny even when added to cells 5 min after infection with SP82. Dominance in these mixed infections could be correlated with qualitative and quantitative differences in the synthesis of phage-specific RNAs.

摘要

在枯草芽孢杆菌的两个菌株中,用两种不相关的噬菌体SP82和β22进行混合感染,研究了子代产量和核酸合成情况。当枯草芽孢杆菌168菌株作为宿主时,先加入的噬菌体主导感染过程;当枯草芽孢杆菌SB11菌株作为宿主时,即使在感染SP82 5分钟后再将β22加入细胞中,β22仍能产生子代。这些混合感染中的主导作用可能与噬菌体特异性RNA合成的定性和定量差异相关。
