Multiple sigma factors are essential to induce the formation of endospores.

Question

Quizplus · Accepted Answer

Multiple sigma factors play different roles in regulating gene expression during the complex process of sporulation, which results in the formation of endospores in some bacterial species. For example, the early stages of sporulation rely on the sigma factor σF, while the later stages require σE and σG among others. Without these sigma factors, the proper genes would not be transcribed and the formation of endospores would be compromised.
