Reconstitution in 6 phases, of the changes in cell shape (in red) and nucleoid structure (roughly equivalent to the DNA, in green), during the cell cycle of the bacteria D. radiodurans

About

This video is part of the Nature communication article "Cell morphology and nucleoid dynamics in dividing Deinococcus radiodurans", which basically presents the discovery of new nucleoid dynamics (the nucleoid is roughly equivalent to the DNA) and the in-depth characterization of Deinococcus radiodurans cell cycle using advanced fluorescence microscopy (super-resolution fluorescence PALM microscopy and spinning-disk confocal microscopy). D. radiodurans undergoes coordinated morphological changes at both the cellular and nucleoid level as it progresses through its cell cycle. The nucleoid is highly condensed, but also surprisingly dynamic, adopting multiple configurations. The nucleoid organization is complex and tightly coupled to the cell cycle progression in this organism.
