Detailed Description

Statement

Reference

CycB²/+ embryos exhibit a significant increase in S-phase length while they do not exhibit any changes in centriole growth rate, growth period or size when compared to controls.

(Aydogan et al., 2018)

CycB² homozygous germaria show an abnormal accumulation of undifferentiated, pre-cystoblast cells, as compared to controls, although about of third of them completely lack germline stem cells. These mutant germaria show an increased number of spectrosome-containing single cells, as compared to controls.

(Flora et al., 2018)

Mutant ovaries contain few or no germ cells.

(Chau et al., 2009)

Over 95% of embryos derived from CycB²/CycB³ ; CycB^2xNRE.hb females have defects in the abdominal segments, the posterior terminalia, or both. In extreme cases, the embryos die with an open posterior hole and not segments following the third thoracic one. The defects appear to arise during nuclear cleavage cycles 9-13; the somatic nuclei in the posterior of the embryos delay progression through cycles 9-13 and ultimately lose contact with the embryonic cortex, falling into the interior.

(Kadyrova et al., 2007)

Mutant embryos appear to start cytokinesis earlier than wild-type embryos. These embryos also appear to stay in cytokinesis longer than normal.

(Echard and O'Farrell, 2003)

Mutant females have rudimentary ovaries and lay few eggs. Homozygotes and hemizygotes reach adulthood.

Statement

Cell death induced by bsk knockdown in cells exhibiting chromosomal instability (through expression of mad2^GD16427) is reduced by lengthening G[[2]] through a CycB² heterozygous background.

(Wong et al., 2014)

Reducing the level of CycB, through a CycB²/+ background, greatly enhances the Scer\GAL4^{nos.UTR.T:Hsim\VP16}>Det^{S125E.Scer\UAS.P\T.T:Avic\GFP} gain-of-function phenotype. Further reduction in the level of CycB, through a CycB²/CycB^KG08886 background, greatly enhances the Scer\GAL4^{nos.UTR.T:Hsim\VP16}>Det^{S125E.Scer\UAS.P\T.T:Avic\GFP} gain-of-function phenotype.

(Mathieu et al., 2013)

The nuclear division defects seen in embryos derived from homozygous Xpd^SH2137 females expressing Xpd^{Scer\UAS.T:SV5\V5} under the control of Scer\GAL4^αTub84B.PL are partially rescued if the females are carrying CycB²/+.

(Li et al., 2010)

Reduction of maternal CycB by one half (using the CycB² allele) in the Capr²/Df(3L)Cat, Fmr1³/+ background partially rescues the premature mitosis 14 phenotype seen in embryos of this genotype. (Reduction of the zygotic contribution of CycB has no effect.)

(Papoulas et al., 2010)

snf¹⁴⁸ ; CycB² double mutant ovaries are not tumourous and contain few or no germ cells, similar to the CycB² single mutant phenotype.

(Chau et al., 2009)

The reduced size of the posterior compartment of the wing that is seen in animals expressing crol^Scer\UAS.cMa under the control of Scer\GAL4^en-e16E is suppressed if they are also heterozygous for CycB².

(Mitchell et al., 2008)

The lethality seen in mei-41^29D males in which excision of an insertion of P{hsw^a} is induced during development is partly suppressed by CycB²/+.

The lethality seen in mei-41^29D males in which excision of an insertion of P{hsw^a} is induced during development is completely suppressed if the female parent carries CycA^C8LR1 and if the male progeny carries both CycA^C8LR1 and CycB².

(LaRocque et al., 2007)

The rough eye phenotype seen in mei-41^29D ; DNApol-α180^Emus304/+ adults is partially rescued by CycB²/+.

(LaRocque et al., 2007)

Adult viability of CycD²/Y ; CycB²/+ males is 90% of expected value.

(Emmerich et al., 2004)

The addition of CycB² has no effect on Myb^unspecified viability.

(Fung et al., 2003)

CycA^C8LR1, CycB² double mutants arrest mesodermal division at mitosis 15 a more severe phenotype than CycA^C8LR1 alone. Also a further reduction in the number of myocardial cells is seen.

(Han and Bodmer, 2003)

CycB3^L6540 CycB^- (CycB² or Df(2R)599-5) double mutants have defective late mitotic figures during mitosis 15 and multipolar spindles at stage 13.
