Uncoupling of cell division and MBT in MZdchs1b mutants. (A) One-cell division from early anaphase to the next early anaphase in WT and MZdchs1b blastula-stage embryos. (B) Quantification of length of cell divisions in WT (blue) and MZdchs1b (red) embryos. (C) Quantification of length of the longest cell axis in 128-cell-stage WT and MZdchs1b embryos. (D) Zygotic expression of boz in MZdchs1b, MZdchs2stl1/stl1 and MZdchs1bfh275/fh275;MZdchs2stl1/stl1 mutants compared with WT relative to MBT. (E) mxtx2 WISH in time-matched WT and MZdchs1b embryos, labeling YSN at 4hpf; animal-pole view. (F) H2B-GFP labeling of YSN in WT and MZdchs1b embryos.
