Genetic Interactions

Statement

Reference

r^Su(b).cSa suppresses the b^unspecified body colour phenotype resulting in a brownish cuticle.

CRMP^supA4 disrupts the suppression of the body colour phenotype of b^unspecified mutants by r^Su(b).cSa.

CRMP^{T:Avic\GFP-EGFP} supports the suppression of the body colour phenotype of b^unspecified, CRMP^supK1 double mutants by r^Su(b).cSa resulting in a brownish cuticle.

CRMP^{fs9a.T:Avic\GFP-EGFP} fails to support the suppression of the body colour phenotype of b^unspecified, CRMP^supA4/CRMP^supK1 double mutants by r^Su(b).cSa resulting in a dark gray cuticle.

CRMP^{fs9b.T:Avic\GFP-EGFP} supports the suppression of the body colour phenotype of b^unspecified, CRMP^supA4/CRMP^supK1 double mutants by r^Su(b).cSa resulting in a brownish cuticle.

(Morris et al., 2012)

Embryos that are homozygous for fs(1)pyr^Su(b) r^Su(b) and b^unspecified and originate from a female homozygous for these 3 mutations show reduced viability; most progeny die at early developmental stages. Embryos that are homozygous for fs(1)pyr^Su(b) r^Su(b)DK7 and b^unspecified and originate from a female homozygous for these 3 mutations show severely reduced viability. Newly laid eggs begin development normally, and early embryogenesis proceeds normally through the syncytial blastoderm, gastrulation and extended germ band stages. Abnormalities such as shrinkage of the embryo and lack of muscle contraction are seen near the end of embryogenesis and the majority of embryos die just before the eggs are due to hatch.

(Piskur et al., 1999)

The b^unspecified black body colour phenotype is suppressed by r^Su(b).cSa but not by r^cSa, r^SE.cSa or r^SA.cSa.

(Simmons et al., 1999)

r^Su(b) b^unspecified flies retain wild-type body colour in the presence of 6-azathymine.
