Figure 7From: Transition to annual life history coincides with reduction in cell cycle speed during early cleavage in three independent clades of annual killifishCell cycle during epiboly and dispersed phase. Cell cycle progression in Nothobranchius furzeri was visualized by fluorescent ubiquitination-based cell cycle indicator (FUCCI). Green cells in the S-/G2 phase, red cells are G1-phase cells. Cells divide for the first days of development at the animal pole (A-B) and then just migrate in G1 onto the embryo surface during late epiboly and the dispersed cell phase (C-D).Back to article page
