Insects provide an attractive system for the study of olfactory sensory perception. We have
identified a novel family of seven transmembrane domain proteins, encoded by 100 to 200 …

Publisher Summary This chapter reviews the morphology and structure of polytene
chromosomes. The chapter focuses on the gene mapping and building of cytogenetic maps …

The mechanism through which gene expression originating from the single male or the two
female X chromosomes in Drosophila is adjusted to autosomal gene expression has …

Matings among different species of animals or plants often result in sterile or lethal hybrids.
Identifying the evolutionary forces that create hybrid incompatibility alleles is fundamental to …

As part of the Human Genome Project, the Washington University Genome Sequencing
Center has commenced systematic sequencing of human chromsome 7. To organize and …

Caspases are widely conserved proteases considered to be essential effectors of apoptosis.
We identified a novelDrosophilagene, dredd, which shares extensive homology to all …

The gene encoding the Drosophila protein phosphatase 2A 55 kd regulatory subunit (PR55)
Is located at 85F and directs the synthesis of differentially spliced transcripts. Maternal RNAs …

During the evolution of the genus Drosophila, the molecular organization of the major
chromosomal elements has been repeatedly rearranged via the fixation of paracentric …

We describe a new Drosophila gene, mini spindles (msps) identified in a cytological screen
for mitotic mutant. Mutation in msps disrupts the structural integrity of the mitotic spindle …

Mothers against dpp (Mad) mediates Decapentaplegic (DPP) signaling throughout
Drosophila development. Here we demonstrate that Medea encodes a MAD-related protein …
