An efficient method for generating embryonic mosaics using a yeast site-specific recombinase (FLP), under the control of a heat shock promoter, is described. FLP-recombinase can promote mitotic exchange between homologous chromosomes that contain FRT (FLP...

The formation of the telson in the Drosophila embryo, which encompasses all structures posterior to abdominal segment 7, is under the control of the "terminal class" genes. These maternally expressed genes are organized in a signal transduction pathway...
The crooked neck (crn) gene of Drosophila encodes a protein of 702 amino acids and contains 16 tandemly arranged copies of a 34-amino-acid repeat that is similar to the tetratrico peptide repeat (TPR). Multiple copies of the TPR motif have also been found...
To generate cell- and tissue-specific expression patterns of the reporter gene lacZ in Drosophila, we have generated and characterized 1,426 independent insertion strains using four different P-element constructs. These four transposons carry a lacZ gene...

The study of serine/threonine kinases in Drosophila is coming of age. Recently several kinases have been identified and their role in cell determination has been established. This review discusses these recent findings and describes the potential for...
The orthodenticle (otd) locus of Drosophila is required for embryonic development, and null mutations of otd cause defects in head development and segmental patterning. We show here that otd is necessary for the formation of the embryonic central nervous...
By means of low-stringency cross-species hybridization to Southern DNA blots, human c-jun sequences were used to identify a unique Drosophila melanogaster locus (Djun). The predicted DJun protein is highly homologous to members of the mammalian Jun family...
In the Drosophila embryo, cell fate along the anterior-posterior axis is determined by maternally expressed genes. The activity of the bicoid (bcd) gene is required for the development of larval head and thoracic structures, and that of maternal torso...
The Drosophila heat shock cognate gene 4 (hsc4), a member of the hsp70 gene family, encodes an abundant protein, hsc70, that is more similar to the constitutively expressed human protein than the Drosophila heat-inducible hsp70. Developmental expression...
The metameric pattern of the Drosophila embryo is regulated by a combination of maternal and zygotic genes. The segment-polarity class of genes are required for the correct patterning within each segmental unit. Mutations in any one of these genes results...
