The mechanisms that underlie the segregation of muscle founder cells in the Drosophila
embryo are undefined. We show that the proneural gene lethal of scute (l'sc) is expressed in …

Adult Drosophila possess a large number of sensory organs, including large and small
bristles and other types of sensilla, each arising from a single mother cell at particular …

The Drosophila exframacrochaefae(emc) locus participates in sensory organ patterning by
antagonizing, in a mechanistically unknown way, the neurogenic activity of the achaete …

The MASH genes are vertebrate homologues of achaete-scute, genes required for neuronal
determination in Drosophila. The sequence of MASH1 and MASH2 contains a basic helix …

Abstract The Drosophila homeoproteins Ara and Caup are members of a combination of
factors (prepattern) that control the highly localized expression of the proneural genes …

The achaete (ac) and scute (sc) genes of Drosophila allow cells to become sensory organ
mother cells. Although ac and sc have similar patterns of expression, deletion of either gene …

The Drosophila gene atonal encodes a basic helix-loop-helix protein similar to those
encoded by the proneural genes of the achaete–scute complex (AS-C). The AS-C are …

Sox proteins form a family of HMG-box transcription factors related to the mammalian testis
determining factor SRY. Sox-mediated modulation of gene expression plays an important …

The neurogenic ectoderm of Drosophila melanogaster consists of the ventral neuroectoderm
and the procephalic neuroectoderm. It is hypothesized that epidermal and central neural …

In Drosophila imaginal discs, the spatially restricted activities of the achaete (ac) and scute
(sc) proteins, which are transcriptional activators of the basic-helix-loop-helix class, define …
