Project description: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. simulans) and that are evolving among species in the D. melanogater subgroup. Keywords: species comparison

Project description:Transcriptomes of four charophyte species
Project description:We sequenced polyA-selected transcriptomes from three species (mouse, rat and chicken), four organs (brain, kidney, liver and testis) and five developmental stages (two embryonic stages, newborn, young adult and aged adult individuals). We analyzed gene expression pattern variations across species, organs and developmental stages for protein-coding and long non-coding RNA genes.

Project description:Insulators are considered as chromosome organizers. BEAF, one of the insulator proteins, is highly conserved in Drosophila speies but also limited to Drosophila spcies. BEAF associates with TSS of active genes. Comparative study of BEAF binding landscapes in four Drosophila species reveals BEAF association with gene pairs, and the results suggest the role of gain or loss of BEAF binding during the speciation of Drosophila species. DNA sample from ChIP for BEAF and input are collected for each of four Drosophila species
Project description:RNA was extracted from adult male and adult female Drosophila simulans carrying small genomic segments introgressed from Drosophila mauritiana Seven introgression genotypes were profiled, as well as the parental D. simulans and D. mauritiana strains. Each sex-by-genotype was assayed on four replicate arrays incorporating a dye swap
