Microscopic elucidation of abundant endophytic bacteria colonizing the cell wall–plasma membrane peri-space in the shoot-tip tissue of banana

Plants are known to harbor endophytic bacteria, the organisms residing internally without imparting any apparent adverse effects on the host. Endophytes are generally known to be present in few numbers colonizing the intercellular spaces, primarily in roots. This study adopting SYTO 9 staining and live confocal imaging of fresh tissue sections from the shoot-tip region of banana, supported by transmission electron microscopy, brings out, possibly for the first time, extensive bacterial colonization in the confined cell wall – plasma membrane peri-space. The integral host-association and their abundance suggest a prominent role of endophytes in the biology of the host.
