Detailed Description

Statement

Reference

Heterozygous Mhc^2D mutant flies show normal dorsal longitudinal muscle morphology.

(Salvi et al., 2012)

Heterozygotes can fly as well as wild-type flies. Homozygotes have a reduced flight index (63.9 +/- 3.2) compared to wild type (78 +/- 6.7).

Genetic Interactions

Statement

Reference

The defects seen in wupA^hdp-2/Y flies are partially suppressed by Mhc^2D/+; 49% of the double mutant adults have an upheld wing phenotype and 51% hold their wings in the normal position. 10% of the indirect flight muscle fibres are hypercontracted, 85% show a partial hypercontraction phenotype and 5% are normal. The wing and indirect flight muscle defects are completely suppressed in wupA^hdp-2/Y ; Mhc^2D/Mhc^2D flies, although the sarcomeres are still shorter than normal. For 6-7 days after eclosion the muscle structure remains completely normal, but after this the central myofibrillar lattice becomes disordered, with characteristic Z-band streaming and gaps in the lattice. The defects seen in up¹⁰¹/Y flies are partially suppressed by Mhc^2D/+; 52% of the double mutant adults have an upheld wing phenotype, 34% have their wings held down and 14% hold their wings in the normal position. 100% of the indirect flight muscle fibres show a partial hypercontraction phenotype. The wing and indirect flight muscle defects are completely suppressed in up¹⁰¹/Y ; Mhc^2D/Mhc^2D flies. 41% of wupA^hdp-3/Y ; Mhc¹²/Mhc^2D flies have an upheld wing phenotype and 59% hold their wings normally.
