The spores formed by Bacillus subtilis remain in a quiescent state for extended periods due to their dormancy and resistance features. Dormancy is linked to a very low level of core water content and a phase-bright state of spores. The present report, focusing on proteins MalS and PdhD (pyruvate dehydrogenase subunit D) and complementary to our companion report published in this issue, aims to shed light on a major dilemma in the field, i.e., whether protein synthesis, in particular that of MalS, takes place in phase-bright spores. Clustered MalS-GFP in dormant spores diffuses throughout the spore as germination proceeds. However, fluorescence intensity measurements, supported by Western blot analysis and SILAC proteomics, confirm that there is no new MalS protein synthesis in bright-phase dormant spores.
