Little is known about broad patterns of variation and evolution of gene expression during any developmental process. Here we investigate variation in genome-wide gene expression among Drosophila simulans, Drosophila yakuba and four strains of Drosophila melanogaster during a major developmental transition?the start of metamorphosis. Differences in gene activity between these lineages follow a phylogenetic pattern, and 27% of all of the genes in these genomes differ in their developmental gene expression between at least two strains or species. more...

(Submitter supplied) Co-expression of genes that physically cluster together is a common characteristic of eukaryotic transcriptomes. Identifying these groups of co-expressed genes is important to the functional annotation of genomes and understanding the evolutionary fates of the clustered genes. We used microarrays to measure gene expression in seven closely related Drosophila species, to identify domains clusters within a species of Drosophila (D. more...

(Submitter supplied) Males hybrids from the crosses between species of the D. simulans clade are steriles as the females are fertiles. Hybrid male sterility is due to severe defects in spermatogenesis and phenotypic differences are observed between the different hybrids involving D. simulans, D. sechellia and D. mauritiana. In this study we are comparing gene expression in the testes of hybrids involving the female D. simulans and the males D. more...

(Submitter supplied) We investigated gene expression levels in Heliconius erato butterflies with divergent wing patterns across a 656KB genomic interval linked to the red color pattern wing polymorphism. This included comparison of expression between two H. erato color pattern populations (H. e. petiverana and a H.e. etylus x H. himera hybrid) across three sections of the forewing that differed in pigmentation (the basal, mid, and distal wing sections) and five different stages of pupal development (Day 1, 3, 5 pupae and ommochrome and melanin pigmentation stages). more...

(Submitter supplied) MicroRNAs (miRNAs) are endogenous RNA molecules that contribute to the regulation of gene expression post-transcriptionally. Recently, patterns of sequence evolution and evolutionary emergence of miRNAs have been analyzed in detail. However, the extent to which miRNA expression levels vary within and between species, the role of stabilizing selection versus other evolutionary mechanisms in shaping the temporal dynamics of these changes, and how this variation might unveil the interplay between miRNAs and mRNAs remain poorly understood. more...

(Submitter supplied) We found two lines of evidence suggesting that miRNA abundance has been shaped by different evolutionary regimes at the two developmental stages. Attributed to functional constraints, which points to mechanisms more subtle and diverse than previously thought.

(Submitter supplied) Larval settlement and metamorphosis is a vital transition period for marine invertebrates and can have far-reaching effects on the ecology and evolution of a species. To explore the molecular mechanisms of this critical process in a non-model organism, the tropical abalone Haliotis asinina, we employed cDNA microarray methods. By comparing gene expression profiles through mid to late larval development and metamorphosis, we identified 144 genes as likely candidates for a role in competence and/or metamorphosis. more...
