Cytology

Description

Construct:osk promoter sequences from about -1750 from the transcription start site drive expression ofosk, in which theosk 3' untranslated region (3'UTR) is replaced bybcd 3'UTR sequences. Thenos response elements are lacking in thebcd 3'UTR sequences.

Detailed Description

Statement

Reference

osk^bcd.UTR causes formation of ectopic pole cells at the anterior in 43% of embryos.

(Suyama et al., 2009)

osk^bcd.UTR embryos have a bicaudal phenotype.

(Anne et al., 2007)

Embryos from mothers that carry 4 copies of theosk^bcd.UTR transgene show approximately double the number of pole cells compared to wild-type embryos.

(Megosh et al., 2006)

Expression ofosk^bcd.UTR results in ectopic anterior pole cell formation in embryos.

(Anne and Mechler, 2005)

P{osk-bcd3'UTR} andP{osk-bcd3'UTR};Tm1^gs1/Tm1^gs1 embryos form two abdomens of opposite polarity.

(Erdelyi et al., 1995)

Homozygous embryos develop mirror image duplication of posterior abdomen and telson structures. In early embryos pole cells are formed at the anterior and posterior poles.

Additional Comments

Genetic Interactions

Statement

Reference

Expression ofosk^bcd.UTR in aLasp^y41 mutant background results in only 10% of blastoderm embryos showing pole cell formation at the anterior. All fertilised eggs develop into embryos that display the bicaudal phenotype.

(Suyama et al., 2009)

csul^P suppresses the bicaudal phenotype ofosk^bcd.UTR embryos. The embryos produced have cuticle with a normal polarity, but the head is malformed. Pole cells are not formed in these double mutant embryos.

(Anne et al., 2007)

The formation of ectopic anterior pole cells seen inosk^bcd.UTR embryos is suppressed invls³ blastoderm embryos.
