TL;DR: In situ hybridizations of norpA cDNA to adult tissue sections show that this gene is expressed abundantly in the retina and that PLC is an essential component of the Drosophila phototransduction pathway.

TL;DR: The absence of glutathione reductase in Drosophila melanogaster is demonstrated, a new type of thioredoxin reduct enzyme is identified, and evidence that a thiOREDoxin system supports GSSG reduction is provided, suggesting that antioxidant defense in Dosophila, and probably in related insects, differs fundamentally from that in other organisms.

TL;DR: It is postulated that the transformation of antennae into second legs is due to the ectopic overexpression of the Antp+ protein, and the dorsal part of the head can be transformed into second thoracic structures (scutum) indicating that Antp indeed specifies the secondThoracic segment.

TL;DR: A collection of P-element insertions that have considerable utility for generating custom chromosomal aberrations in Drosophila melanogaster are described and their end points mapped, with base-pair resolution, to the genome sequence.

TL;DR: It is demonstrated that eyelet derives from the 12 photoreceptors of Bolwig's organ, which entrain circadian rhythmicity in the larva, and a functional role in circadian entrainment first found in Bolwig’s organ in the Larva is retained in eyelet, the adult remnant ofbolwig's organs, even in the face of metamorphic restructuring.
