In cdc2B47 mutants, the NB6-4t lineage develops as in wild-type, generating two glial cells and five-to-six dorso-lateral neurons.
When cdc2B47/cdc2E1-24 animals are raiseds at a semi-restrictive temperature (26oC), flies develop until the end of pupariation, but fail to hatch. These animals exhibit a severe loss of bristles. In addition, at 26h APF about 50% of sensory organs are composed of only two cells, lacking shaft and socket cells.
Lethal phase is during the larval/pupal stage. Homozygous embryos develop essentially normally. RP2 neuron duplication and large RP2 neurons are seen in only 3.6% and 3% of cases respectively. Duplication of muscle DA1 can be seen in embryos carrying four copies of cdc2A171T (in a cdc2B47 background) which have been shifted to the non-permissive temperature. RP2 neuron duplication and large RP2 neurons are seen in 42.7% and 4.6% of cases respectively. Temperature upshifts can also result in the arrest of neuroblasts in G2 in these embryos.
Somatic clones in the wing lead to wing cells that are larger than normal which produce either longer than normal wing hairs, or double wing hairs.
The cdc2B47/cdc2E1-24 combination is temperature sensitive. cdc2B47/cdc2E1-24 third instar mutants the size of the central nervous system and imaginal discs is severly reduced. Many of the mutants cells in the CNS, salivary gland and imaginal discs are larger and more intensely DAPI-staining than wild type. Cell division is reduced but BrdU incorporation occurs in the salivary gland imaginal ring and CNS during the third instar. Mutations at esg have no further effect on these mutant phenotypes. In cdc2B47/Df(2L)J27, many cells of the outer part of the optic lobe contain huge bnanded polytene chromsomes comparable in size and morphology to the salivary gland polytene chromosomes. Abdominal histoblasts in cdc2B47/cdc2E1-24 larvae accumulate BrdU without increasing cell number, suggesting they are in endocycle.
Males carrying two or four copies of P{Dmcdc2A171T} at 18oC or 29oC exhibit a reduction in testis cell number and increase in size of the nucleus and Nebenkern. Results indicate only one meiotic division occurs in males with two copies of P{Dmcdc2A171T} and no meiotic divisions in males with four copies. Males carrying two copies still exhibit spermatid differentiation.
Larvae contain no imaginal discs. Brain development is abnormal.
Die after pupariation at the larval-pupal interface. Larvae take 1-2 days longer than wild type to reach the wandering stage. Imaginal discs are missing or rudimentary and larval brains are reduced in size. Endoreplication and polytenization of larval cells is normal, as are salivary gland size and intensity of DNA staining of their polytene nuclei.
