Detailed Description

Statement

Reference

Heterozygotes have a very mild phenotype with some thoracic bristles occasionally being missing. Homozygotes lack all bristles on the lateral part of the notum, so that only a median stripe of bristles remains. The mesothorax is narrower than normal, and has no notopleural suture. The scutellum is smaller than normal, and the wings are raised. ara¹/Df(3L)iro-2 flies are viable and have a phenotype similar to ara¹ homozygotes. ara^rF209/ara¹ flies show a weak iroquois phenotype, with some, but not all, of the lateral bristles on the notum being missing.

(Leyns et al., 1996)

Only the median strip of hairs remains on the notum.

Additional Comments

Genetic Interactions

Statement

Reference

ara¹ caup¹/Df(3L)iro-2 flies lack lateral macrochaetae and the most lateral of microchaetae of the notum. The humeral bristles are normal and have wild-type axonal projections in these flies although the humerus is not morphologically normal. Bristles of variable size are formed in the otherwise naked lateral region of the notum if the flies are also carrying ac^Hw-49c, at a position corresponding to that of the posterior supraalar bristle. This bristle has a contralateral axon branch in about 70% of cases.

(Grillenzoni et al., 1998)

ara¹/ara¹ flies carrying sc^hs.PR develop tufts of bristles in the lateral part of the notum (that is normally naked in ara¹ homozygotes) after heat shock. Double heterozygotes with Df(4)M101-62f or Df(1)260-1 have a much stronger phenotype, with some bristles missing at a high frequency.
