枯草芽孢杆菌的螺旋生长：一种新的细胞生长模型。

Proc Natl Acad Sci U S A. 1976 May;73(5):1740-4. doi: 10.1073/pnas.73.5.1740.

A multiple mutant of Bacillus subtilis that grows in an unusual double-helix morphology was studied. Construction of models led to the assumption that cell surface elongation must proceed in a helical path in this mutant. The observation that all newly formed double-helix clones propagated, after spore outgrowth in fluid culture, consisted of closed-circular structures suggested that double-helix structures are tension-registered forms.

对一种以异常双螺旋形态生长的枯草芽孢杆菌多重突变体进行了研究。模型构建得出这样的假设：在这种突变体中，细胞表面的伸长必定沿螺旋路径进行。在液体培养中孢子萌发后，所有新形成的双螺旋克隆体都能繁殖，且均由闭环结构组成，这一观察结果表明双螺旋结构是张力记录形式。
