  This manuscript presents important findings on how structural color can be manipulated through a specific single-gene mutation in a motile bacterium. Compelling data provide a promising model to identify genes and molecular mechanisms supporting this widespread optical phenomenon. This work will be of interest to biophysicists and microbiologists working on structural colors and Flavobacterium.

  This valuable study provides insights into the structure and function of bacterial contractile injection systems that are present in the cytoplasm of many Streptomyces strains. A convincing high-resolution model of the structure of extended forms of the cytoplasmic contractile injection system assembly from Streptomyces coelicolor is presented, with some investigation of the membrane protein CisA in attachment of the extended assembly to the inner face of the cytoplasmic membrane and the firing of the system. The work expands the current understanding of these diverse bacterial nanomachines.

  This study presents valuable findings about daily rhythm changes of the Drosophila melanogaster adult gut metabolome, which is shown to be dependent on the circadian clock genotype, dietary regime and composition, and gut microbiota. The phenomena observed are supported by convincing experimental evidence. The general descriptive approach limits the power of the proposed conclusions. The work will be of interest to a broad range of physiology specialists

  The findings in this manuscript are fundamental because they identify an entry receptor MYL3 that belongs to the myosin family as a possible target that could inhibit a virus that has a high impact on aquaculture. The evidence is convincing as it contains strong in vitro and in vivo data that support their conclusions; however, studies on the presence of MYL3 in NNV target tissues will further strengthen their claims

  The manuscript explores how bacterial evolution in the presence of lytic phages modulates b-lactams resistance and virulence properties in methicillin-resistant Staphylococcus aureus (MRSA). This important work improves our knowledge of how mutation in genes required for phage infection confers sensitivity to b-lactams and alter virulence properties. Altogether, the findings are convincing.
