Fig. 9. F-actin structures in spg1-B8, cdc7-24 and sid2-250 mutant cells. Green, red and blue represent F-actin, SPBs and DNA, respectively. (a,b) A cdc7 mutant cell at late anaphase. (c,d) A sid2 mutant cell at late anaphase. An incomplete F-actin ring (pink arrow) is connected to a complete F-actin ring (white arrow). (e,f) A cdc7 mutant cell after anaphase. (g,h) spg1 mutant cells. White arrow, remaining F-actin ring. Pink arrow, a remnant of disappearing F-actin ring. (a,c,e,g) 3D images of chromosomes and SPBs. Pink and white arrowheads represent pairs of sister SPBs. (b,d,f,h) 3D images of F-actin structures. Bar, 2 µm.
