Detailed Description
Statement
Reference

Deficient or thin muscles are sometimes seen in the abdominal segments of homozygous larvae.

Muscle attachment defects are observed in rt2 mutant third instar larvae. Sarcomeres are larger than in wildtype animals.

Muscle attachment defects are observed in rt2/rtP mutant third instar larvae. Sarcomeres are larger than in wildtype animals.

rtP/rt2 flies have rotated abdomens.

The bodies of first instar larvae are rotated around the long axis, forcing the animals to move in a clockwise circle as they crawl. The larval cuticle presents a perfect segmental alignment of landmarks but the adult abdominal cuticle segments appear staggered relative to each other. Embryos show a variable but fully penetrant mutant phenotype. Common phenotypes include the lack of some muscles or the presence of very elongated thin ones. Most affected muscles are the lateral muscles 4, 5, 8, 23 and 24. Dorsal muscles are less commonly missing.

Abdomen twisted, as is rt. Viability erratic, usually about 50% wild type. Male fertile; female not tested. RK2.

Double homozygous Dg323;rt2 larvae show changes in sarcomere size and muscle attachment defects, identical to those seen Dg323 homozygous animals.

A greater number of muscle attachment defects are observed in tw1; rt2 mutant third instar larvae compared to rt2 mutants. Sarcomeres are larger than in wildtype animals.

A greater number of muscle attachment defects are observed in tw1; rt2/rtP mutant third instar larvae compared to rt2/rtP mutants. Sarcomeres are larger than in wildtype animals.

Expression of the twScer\UAS.T:Ivir\HA1 transgene, under the control of Scer\GAL4Act5C.PI, does not enhance the abdominal phenotype of rtP/rt2 mutants. This phenotype is also not affected by tw RNAi, achieved by expression of twdsRNA.Scer\UAS under the control of Scer\GAL4Act5C.PI.
