Description

P{GawB} insertion close to the transcription start sites for the B, C and D lov mRNAs and within the large second intron of the A transcript.

(Bjorum et al., 2013)

P{GawB} insertion 465 bp 5' of start of CG16778 transcript RB; 1406 bp 5' of start of CG16778 transcript RA; approximately 37 kb into approximately 40-kb first intron (5' UTR) of CG16778 transcript RC.

      lov91Y adults show wild type climbing ability.

      lov91Y males display non-directed courtship (i.e. while not pursuing the female).

      In the absence of females, lov91Y males show wild type locomotor activity levels.

      (Bjorum et al., 2013)

      Flies show an aberrant gravitaxic response in a vertical gravitaxic maze assay, and show wild type behaviour in a horizontal maze. Male courtship activity is comparable to wild type, and flight is not seriously impaired.

      (Armstrong et al., 2006)

      91Y91Y virgin females show elevated ovulation; 19% of the virgin females show ovulation (compared to 0% of virgin Oregon-R females). The flies show no obvious defects in viability, fertility, morphology or locomotor activity. The courtship index observed when 91Y91Y virgin females are mated to wild-type males is lower than that seen when wild-type virgin females are mated to wild-type males, but is higher than that seen when wild-type mated females are mated to wild-type males. 91Y91Y mutant virgin females show ovipositor extrusion towards courting wild-type males (this extrusion behaviour is normally observed in mated wild-type females but not in virgin wild-type females).
