iPALM imaging reveals that nucleoids are not restricted to ellipsoidal boundaries. TFAM-mEos2-labeled nonelliptical nucleoids exhibit concave, split, and amorphous forms. The fluorescent molecule scale maximum values (representing probability per square nanometer) differ among the panels and range from 0.14 to 0.19. Collectively, these examples represent about 35% of the nucleoid population. Bar, 100 nm (the scale bar in panel A applies to all panels).
