Embryos derived from females carrying four copies of CycB+t10 (as well as two wild-type copies of CycB+) show multiple nonlethal phenotypes, one of which is a delay in arrival of the nuclei to the cortex. 91% of these embryos have normal nuclear morphology at cycle 10, while in later blastoderm cycles the frequency of these embryos with normal nuclear morphology drops to 76% and is lowest at cycle 12. The abnormal embryos show one or more of the following mutant phenotypes; patches of extra mitoses, areas of the blastoderm devoid of nuclei, chromosomal bridges and/or macro- or micro-nuclei. M-phase is seen at cycle 14 in these embryos. More than 90% of these embryos hatch and develop to adulthood.

Embryos derived from females carrying four copies of CycB+t10 (as well as two wild-type copies of CycB+) have a shorter interphase duration than normal and a longer prophase-metaphase duration than normal in cycles 10, 11, 12 and 13, while the anaphase-telophase duration is normal during these cycles.

Embryos with two extra copies of the maternal CycB+ gene dose (derived from females carrying copies of CycB+t10) show a delay in the onset of anaphase (measured during cycles 6-11) compared to wild type. Nuclear cortical migration is initiated at telophase of cycle 9 and ends about 1.5 minutes into early interphase of cycle 10, as occurs in wild-type embryos, but the velocity and pattern of nuclear migration is abnormal; nuclei move move slowly than normal and they move to the cortex like "drunken soldiers" - moving in meandering lines towards the cortex (the nuclei migrate in straight paths perpendicular to the cortex in wild-type embryos). Embryos with four extra copies of the maternal CycB+ gene dose (derived from females carrying copies of CycB+t10) have an abnormal nuclear distribution at cycle 10, with nuclei at the anterior-medial region failing to reach the cortex simultaneously in more than 80% of embryos. Embryos with four extra copies of the maternal CycB+ gene dose (derived from females carrying copies of CycB+t10) have a slightly lower hatching rate and a higher frequency of abnormal nuclear distribution and morphology at cycle 14 interphase. Embryos with four extra copies of the maternal CycB+ gene dose (derived from females carrying copies of CycB+t10) have a reduced microtubule network (measured during early interphase of cycle 9). These embryos have a significantly higher fraction of metaphase spindles with no visible astral microtubules at cycle 9 than wild-type embryos.

Embryos carrying the CycB+t10 transgene show mitotic defects such as loss of cell synchrony but do not contain interacting spindles or multipolar spindles. During mitosis of cycle 12, CycB+t10 embryos show normal localization of nuclei and centrosomes.

The velocity of sister chromatid separation in anaphase of mitotic cycles 6-8 increases significantly with increasing maternal CycB gene dosage: CycBunspecified/+ < wild-type < 2XCycB+t10. This is reflected in a decrease in anaphase duration. The duration of prophase + metaphase between cycles 6 and 10 increases with increasing maternal CycB gene dosage (genetics as above), but the length of interphase during these cycles decreases with increasing maternal CycB gene dosage (CycBunspecified/+ > wild-type > 2XCycB+t10. This latter effect is particularly pronounced in later mitotic cycles (10 and 11).

Embryos derived from females carrying six copies of CycB (4 copies of CycB+t10 in a wild-type background) show defects at nuclear cycle 10; nuclei reach the periphery of the embryo later and nonsynchronously and it takes more than one cycle for a uniform distribution of nuclei at the cortex to form. 26% of these embryos have patches of mitotic nuclei during cycle 14 interphase and areas of lower nuclear density. Chromosomal bridges and macro- and micronuclei are occasionally seen. These embryos have only a slightly reduced hatching rate (92% compared to 96% in controls). Only 60% of cycle 5-7 embryos have metaphase spindles with asters, compared to 84% in wild-type controls. Energids in these embryos migrate at a rate of 8.9μm/min, which is slower than in wild type. The embryos have one more axial expansion cycle than normal and nuclei move slightly but for a significantly longer time. It takes longer and more than one cycle for all somatic buds to appear at the surface of the embryo.

CycB+t10 does not result in the onset of mitosis in wild-type nurse cells.

93% of embryos derived from females carrying four copies of CycB+t10 (as well as two wild-type copies of CycB+) and also heterozygous for Df(2L)Exel7080 have a normal phenotype at cycle 14, while only 25% of these embryos have a normal phenotype at cycle 10.

The shorter than normal interphase duration seen in embryos derived from females carrying four copies of CycB+t10 (as well as two wild-type copies of CycB+) is not suppressed by RPA22/+ at cycle 10 or 11, but is partially suppressed by RPA22/+ at cycle 12 and is suppressed by RPA22/+ to wild type duration at cycle 13.

The delay in onset of anaphase (measured during cycles 6-11) seen in embryos with two extra copies of the maternal CycB+ gene dose (derived from females carrying copies of CycB+t10) is enhanced by thr1 and is suppressed by pimIL or Sse13m. Nuclear cortical migration is initiated at telophase of cycle 9 and ends about 1.5 minutes into early interphase of cycle 10 in embryos with two extra copies of the maternal CycB+ gene dose (derived from females carrying copies of CycB+t10) and carrying either pimIL or Sse13m, as occurs in wild-type embryos, but the velocity and pattern of nuclear migration are abnormal; nuclear movements are faster than in wild-type embryos and the nuclei move in curved paths and at an angle to the cortex (the nuclei migrate in straight paths perpendicular to the cortex in wild-type embryos). The reduction in the microtubule network (measured during early interphase of cycle 9) seen in embryos with four extra copies of the maternal CycB+ gene dose (derived from females carrying copies of CycB+t10) is suppressed by pimIL/+ or Sse13m/+. The loss of astral microtubules seen in cycle 9 embryos with four extra copies of the maternal CycB+ gene dose is enhanced if they also carry Sse13m/+ or Df(3L)SseA/+.

Embryos derived from png2 homozygous females that are also carrying multiple copies of CycB+t10 show a striking increase in the number of nuclei in each embryo compared to embryos derived from png2 females, as well as an increase in the number of embryos with multiple nuclei. The polar bodies contain condensed chromosomes with a normal rosette arrangement. The chromosomes of the zygotic nuclei are condensed and mitotic figures are visible. However, all the embryos contain polyploid nuclei and none survive past embryogenesis. 39% of embryos derived from plu6 females carrying 4 copies of CycB+t10 are multinucleated, compared to only 1.5% of those derived from plu6 single mutant females. The polar body defects are not corrected. 65% of embryos derived from gnu305 females carrying 4 copies of CycB+t10 are multinucleated, compared to only 0.8% of those derived from gnu305 single mutant females. The polar body defects are not corrected.
