Diplo-X flies homozygous for the transform-er-2 ts (tra-2 ts) mutation develop into females at 16° C, while they develop into males at 29° C (Belote and Baker 1982). By means of this conditional mutation, we have carried out a detailed analysis of the development of the genital disc. Temperature shifts between 16 and 29° C, in both directions, and… (More)
FHX (FOXJ2) is a recently characterized human fork head transcriptional activator that binds DNA with a dual sequence specificity. We have cloned the cDNA for the mouse orthologue Foxj2 and characterized its expression in the gonads and along the early pre-implantation development of the mouse. In the testis, Foxj2 is expressed from pachytene spermatocytes… (More)
DmFoxF is a novel Drosophila fork head domain factor, which is expressed in the visceral mesoderm of the embryo. Our data suggest that DmFoxF is the fly orthologue of the vertebrates FOXF1 and FOXF2 transcription factors. DmFoxF shares homology with FOXF1 and FOXF2 in its fork head domain, and it is able to specifically bind DNA sequences recognized by… (More)
Figure S1. Labial expression rescues constriction formation in FoxK mutant embryos. (A and B) Embryos mutant for FoxK do not develop constrictions in the midgut, but overexpressin of laboratory in the endoderm results in the formation of multiple vesicles (A, arrow). However, the morphology of the gut is still abnormal because of the excess of laboratory.
