Multimodal Molecular Imaging Reveals a Novel Membrane Component in Sporangia of the Rare Actinomycete .

The bacterium belongs to the genus , a prolific source of useful natural products. This microbe forms globular structures called sporangia, which contain many dormant spores. Recent studies using transmission electron microscopy have shown that the sporangium membrane has an unprecedented three-layer structure, but its molecular components remain unclear.
