Project description:Anopheles gambiae, the primary African malarial mosquito, exhibits numerous behaviors that are under diel and circadian control, including locomotor activity, swarming, mating, host seeking, eclosion, egg laying and sugar feeding. However, little has been performed to elucidate the molecular basis for these daily rhythms. To study how gene expression is globally regulated by diel and circadian mechanisms, we have undertaken a DNA microarray analysis of A. gambiae head and bodies under 12:12 light:dark cycle (LD) and constant dark (DD, free-running) conditions. Zeitgeber Time (ZT) with ZT12 defined as time of lights OFF under the light:dark cycle, and ZT0 defined as end of the dawn transition. Circadian Time (CT) with CT0 defined as subjective dawn, inferred from ZT0 of the previous light:dark cycle.

Project description:The mosquito Ae. aegypti is responsible for the transmission of many diseases including yellow fever and Dengue fever. This species exhibits many behaviors that are under diel and circadian control. However, there has been little reporting on gene expression rhythmicity. To study how gene expression is globally regulated by diel and circadian mechanisms, we have undertaken a DNA microarray analysis of Ae. aegypti head and bodies under 12:12 light:dark cycle (LD) and constant dark (DD, free-running) conditions. Zeitgeber Time (ZT) with ZT12 defined as the initiation of the one hour dusk period under the light:dark cycle, and ZT0 defined as beginning of the one hour dawn period. Circadian Time (CT) with CT0 defined as subjective dawn, inferred from ZT0 of the previous light:dark cycle.

Project description:Following divergence from Arabidopsis thaliana, Brassica rapa underwent a whole genome triplication followed by extensive genome fractionation. Preferential retention of circadian clock genes suggest that expansion of the circadian network may play an important role during B. rapa domestication. To characterize the circadian transcriptome network, RNA-seq was performed in the B. rapa oil-type variety R500 following photocycle and thermocycle circadian time courses. The photocycle (LDHH) time course consisted of growing plants for 15 days at 20°C under a 12h light/12h dark photoperiod and transfering plants to constant light and 20°C 24h prior to harvesting leaf tissue every 2h for 48h starting at ZT24 with 2 biological replicates at every time point. The thermocycle (LLHC) time course consisted of growing plants for 15 days under constant light with a 12h 20°C/12h 10°C thermoperiod and transfering plants to constant light and 20°C 24h prior to harvesting leaf tissue every 2h for 48h starting at ZT24 with 2 biological replicates at every time point.

Project description:In most organisms biological processes are partitioned, or phased to specific times over the day through interactions between external cycles of temperature (thermocycles) and light (photocycles), and the endogenous circadian clock. This orchestration of biological activities is achieved in part through an underlying transcriptional network. To understand how thermocycles, photocycles and the circadian clock interact to control time of day specific transcript abundance in Arabidopsis thaliana, we conducted four diurnal and three circadian two-day time courses using Affymetrix GeneChips (ATH1). All time courses were carried out with seven-day-old seedlings grown on agar plates under thermocycles (HC, hot/cold) and/or photocycles (LD, light/dark), or continuous conditions (LL, continuous light; DD, continuous dark, HH, continuous hot). Whole seedlings (50-100), including roots, stems and leaves were collected every four hours and frozen in liquid nitrogen. The four time courses interrogating the interaction between thermocycles, photocycles and the circadian clock were carried out as two four-day time courses. Four-day time courses were divided into two days under diurnal conditions, and two days under circadian conditions of continuous light and temperature. Thermocycles of 12 hours at 22C (hot) and 12 hours at 12C (cold) were used in this study. The two time courses interrogating photoperiod were conducted under short days (8 hrs light and 16 hrs dark) or long days (16 hrs light and 8 hrs dark) under constant temperature. In addition, the photoperiod time courses were in the Landsberg erecta (ler) accession, in contrast to the other time courses that are in the Columbia (col) background. The final time course interrogated circadian rhythmicity in seedlings grown completely in the dark (etiolated). Dark grown seedlings were synchronized with thermocycles, and plants were sampled under the circadian conditions of continuous dark and temperature.

Project description:Arabidopsis thaliana circadian and light signaling mutants have long hypocotyls under light/dark cycles. In order to determine if aberrant hypocotyl growth is due to time of day specific miss-expression of growth associated transcripts we conducted time course microarray experiments in the lux-2, lhy and phyB-9 mutants. The mutants and their parental genotypes were grown on plates under either intermediate days (12 hours light and 12 hours dark) for lux-2, or short day (8 hrs of light and 16 hrs of dark) for lhy and phyB-9, for seven days and tissue was collected every four hours over one day.

Adult mated but non-blood fed female mosquito heads and bodies under 12:12 light:dark cycle (LD) and constant dark (DD) conditions were collected every 4 hr to generate 48 hr gene expression profiles, and samples were processed with Affymetrix full genome microarrays. Downstream analysis identified genes with ~24hr rhythmic expression profiles.

Project description:The dark-phase in light/dark cycle plays an important role in successful disease development in M. oryzae-Oryza sativa. We used microarrays to detail the global programme of gene expression in response to light-to-dark transition. We identified different groups of genes (based on GO categories) that are up- or down-regulated in response to light-to-dark transition. Keywords: time course
