Abstract

A new mutant of Bacillus subtilis defective in the outgrowth phase of spore germination has been isolated. When incubated at 46 C, the spores of the mutant gave rise to abnormally large swollen cells. Genetic crosses show that the mutant is different from the three previously described. The genetic analysis indicates two regions of the B. subtilis chromosome involved in the control of the spore outgrowth.

摘要

已分离出一种在芽孢萌发的生长阶段存在缺陷的枯草芽孢杆菌新突变体。当在46℃下培养时,该突变体的芽孢会形成异常大的肿胀细胞。遗传杂交表明该突变体与之前描述的三种不同。遗传分析表明枯草芽孢杆菌染色体的两个区域参与芽孢生长的控制。
