(A to F) Embryos of WT and ncp1 from 1-cell stage to transition stage. Red arrowheads point to the abnormal cell divisions in pro-embryos and suspensor cells at 8-cell (C) and 16-cell stages in ncp1-1 (D), and in hypophysis at the globular stage in ncp1-1 (E). (G, H) Defects of ncp1-1 pid embryos at heart and torpedo stages. From left to right: WT, ncp1-1, ncp1-1 pid, and pid.
