Cover Story: Single-stranded RNA bacteriophages (ssRNA phages) infect a variety of Gram-negative bacteria. Combining computational modeling and single-particle cryo-electron microscopy, Chang et. al. built the complete structure of an ssRNA phage, Qβ. From the structure, they revealed RNA/RNA and RNA/protein interactions based on which to propose a pathway for virion assembly. Interestingly, different forms of the Qβ virus-like particles (VLPs) were purified from an infection event, revealing that there are non-canonical pathways of viral assembly in nature, and the length of the encapsidated RNA may affect the formation of these VLPs. These results provide structural insights into virion assembly in ssRNA phages. View this paper
