Subject: addition to the FlyBase report Dear Rachel, might I made an addition to the FlyBase report about leg-arista-wing-complex (lawc) gene ? As lawc and l(1)EF520 are allelic (see below), > The complementation test showed that there was no heteroallelic >complementation between EMS-induced embrionic lethal l(1)EF520 and lawcp1. > (Simonova et al., A. Dros. Res. Conf. 39: 333A) lawc localization should be changed from 7F1 to 7E4 cytological map position (Perrimon et al. 1989, Genetics, 121: 333-352). Besides, I would like to notes that phenotype of some mutations, which are at the same position of the genetic map, are resemble lawc phenotype, excluding homeotic transformation arista to tarsus. This mutations had been obtained by Neel and Fahmy (DIS-33: 81-94) and were lost now. Do compare: > Symbol scr1 > Discoverer Neel, 22nd Feb. 1941. > FlyBase ID FBal0015276 > Genetic location 1-22.0 > Phenotypic info. > > Hairs and bristles missing or doubled and deranged. Eyes small and > rough. Scutellum more convex than wild type. Wing margins, especially > posterior, often incised. Wings occasionally blistered. All characters > variable; a few flies appear normal.
