Larvae of NPD strain (npd-mutants) do not respond to photoperiod. Our previous results indicated that the locus npd could code for the timeless gene and its product might represent a molecular link between circadian and photoperiodic clock systems. Here we present results of tim mRNA and TIM protein analyses in the larval brain. TIM protein was localized in 2 neurons of each brain hemisphere of the 4-d-old 3rd instar wild-type larvae. In a marked contrast, no TIM neurons were detected in the brain of 4-day-old 3rd instar npd-mutant larvae and the level of tim transcripts was approximately 10-fold lower in the NPD than in the wild-type strain. Daily changes in tim expression and TIM presence appeared to be under photoperiodic control in the wild-type larvae. Clear daily oscillations of tim transcription were observed during the development of 3rd instars under the short-day conditions.
