Transcription profiling of Drosophila yw LD/DD time series tim01 Drosophila #1

ABSTRACT: Background. The transcriptional circuits of circadian clocks control physiological; and behavioral rhythms. Light may affect such overt rhythms in two ways: (1) by; entraining the clock circuits and (2) via clock-independent molecular pathways. In; this study we examine the relationship between autonomous transcript; oscillations and light-driven transcript responses; Methodology/Principal Findings. Transcript profiles of wild-type and arrhythmic; mutant Drosophila were recorded both in the presence of an environmental; photocycle and in constant darkness. Systematic autonomous oscillations in the; 12-48 hr period range were detectable only in wild-type flies and occurred; preferentially at the circadian period length. However, an extensive program of; light-driven expression was confirmed
