(Submitter supplied) We analyzed genome-wide temporal transcriptional patterns from Daphnia pulex collected over a 48 hr time period using a cosine-fitting algorithm. Additionally, using a comprehensive network modeling and analysis approach, we go beyond the standard statistical analyses of the gene expression data. By doing so, we identified novel co-regulated rhythmic genes that have similar network topological as well as functional annotations as rhythmic genes identified by the statistical analyses but that cannot be identified by cosine-fitting alone. more...

(Submitter supplied) 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. more...

(Submitter supplied) 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. more...

(Submitter supplied) This study measured the differential expression of genes from a single clonal Daphnia pulex isolate obtained from an eutrophic flooded opencast mine near Gräfenhain (Saxony, Germany) and has been kept in the laboratory since 2002. The daphniids (50 adult animals per batch) were raised in 3-L glass beakers under a 16 h:8 h L:D photoperiod. Three-quarter of the culture medium (M4) was renewed once a week, and the animals were equally fed ad libitum with algae (Desmodesmus subspicatus; SAG 53.80, Göttingen, Germany). more...

The conditions were designated A to L. The number and diversity of experiments were designed to uncover condition specific expression. The age of duplicated genes was measured as the level of silent-site nucleotide substitution (Ks) between paralogs. more...

(Submitter supplied) Across evolutionary time, nearly all animal species have harnessed photoperiod to initiate processes that ultimately influence seasonal behavior and life history traits. In the freshwater cladoceran Daphnia magna, the effect of photoperiod on various life history traits has generally been investigated in conjunction with additional environmental stimuli. In the present study, we sought to untangling responses directly attributable to photoperiod in D. more...
