Df(2L)Msp-300-compl removes the whole Msp-300 locus, along with the Cyp28d2 putative coding sequence, between the insertions P{XP}d07933 and PBac{WH}f05524.
Myonucleus positioning appears normal in the DA1, DO1, DA2 and DO2 dorsal muscles of Msp-300compl stage 16 mutant embryos.
Msp-300compl homozygotes are larval lethal. They do not display any obvious phenotype and move normally. Over time, the movements become slower and the larvae die before entering the second instar. There is no detectable difference in the arrangement or the movement of the body wall muscles of wild-type and mutant individuals when observing the larvae in polarised light.
Msp-300compl germline clones lay normal eggs, with no observable defects in nuclear position or nuclear architecture in the egg chambers.
Msp-300compl mutant cell clones do not cause defects in the eye imaginal disc.
Msp300compl/Msp300[+] is a suppressor | partially of increased cell death | somatic clone | oogenesis phenotype of kudKO
Msp300compl is a non-enhancer of eye phenotype of klarmarb-BX12
Msp300compl/Msp300[+] is a suppressor | partially of follicle cell | somatic clone | oogenesis phenotype of kudKO
Msp300compl heterozygosity partially suppresses the increased apoptosis observed in kudKO homozygous follicular epithelium clones.
In Msp-300compl klarΔ1-18 double heterozygous third instar larvae the myonuclei are aberrantly positioned but, as in wild type, they are still associated with the acto-myosin network.
Female Msp-300compl;klarmarb-BX12 double mutants lay normal eggs and exhibit wild-type egg chambers. In addition, no defects are found in Msp-300compl mutant follicle cell clones generated in klarmarb-BX12 homozygous mutant females.
Msp-300compl;klarmarb-BX12 mutants do not exhibit any morphological alterations in the nuclei of nurse cells or in the oocyte.
Induction of Msp-300compl mutant cell clones in a klarmarb-BX12 homozygous mutant background in the wing imaginal discs does not affect nuclear positioning.
Msp-300compl mutant cell clones do not enhance the klarmarb-BX12 mutant rough eye phenotype.
Msp-300compl;klarmarb-BX12 double mutants do not exhibit any difference in nuclear morphology (or localisation) at any time point during early embryogenesis.
A Dp(2;1)B19 background rescues the lethality of Msp-300compl mutants.
