Circadian Regulation of Gene Expression Systems in the Drosophila Head

Mechanisms composing Drosophila's clock are conserved within the animal kingdom. To learn how such clocks influence behavioral and physiological rhythms, we determined the complement of circadian transcripts in adult Drosophila heads. High-density oligonucleotide arrays were used to collect data in the form of three 12-point time course experiments spanning a total of 6 days. Analyses of 24 hr ...

A Homologous Gene-enzyme System, Esterase 6, in Drosophila Melanogaster and D. Simulans.

HE existence in natural populations of a protein polymorphism involving Ttwo forms of a nonspecific esterase has been established in Drosophila mlamgaster (WRIGHT 1961, 1963). The two forms of the esterase, Esterase 6, are distinguishable by their different electrophoretic mobilities in starch gel, Esterase 6" migrating more rapidly toward the anode than Esterase 6s. The inheritance of these tw...

The Drosophila sugarless gene modulates Wingless signaling and encodes an enzyme involved in polysaccharide biosynthesis.

We have identified and characterized a Drosophila gene, which we have named sugarless, that encodes a homologue of vertebrate UDP-glucose dehydrogenase. This enzyme is essential for the biosynthesis of various proteoglycans, and we find that in the absence of both maternal and zygotic activities of this gene, mutant embryos develop with segment polarity phenotypes reminiscent to loss of either ...

Effects of substrates on gene-controlled enzyme activities in cultured embryonic cells of Drosophila.

O N E of the central pr’oblems in the genetics of differentiation may be formulated in the following way: Why do embryonic cells possessing the necessary genetic information fail to synthesize certain specific proteins, and what are the mechanisms which are responsible for the initiation of such synthesis in particular cell lines at subsequent stages of development? The development of methods f...
