(Submitter supplied) We designed a custom expression 8x15 k microarray for Cottus fishes based on transcriptome sequencing. It is a known fact, that oligonucleotide probes differ in the binding behavior towards their target sequences. Therefore, we performed a calibration of our microarray where we assessed the binding behavior of the individual probes empirically. This information was used to normalize gene expression data measurements with the same microarray in another experiment. more...

(Submitter supplied) European sculpins (Cottus) harbor an example of a recent hybrid speciation event, which entails the invasion of a new habitat by the hybrid species. We compare the transcriptomes of both parental species and the hybrid species to understand how they differ. F2 crosses between the parent species are compared to the hybrid species and its parent species to identify unique patterns of the hybrid species due to the initial hybridization process or respectively to other processes. more...

(Submitter supplied) Hybridization between Cottus rhenanus and C. perifretum has resulted in an evolutionary young hybrid lineage of invasive Cottus that has colonized a new habitat where the parental species are not found (Nolte et al. 2005; Proc. R. Soc. B 272: 2379–2387). This CGH array was designed to screen for copy number variation among Cottus species and to find gene duplicates that are unique to the hybrid lineage (see also Dennenmoser et al. more...

(Submitter supplied) Calibration array used to assess probe specific binding behaviour across eight different amounts of DNA starting material. This calibration step was performed to select one best out of three probes per gene based on probe responsiveness on increasing DNA staring material. It was further used to calibrate a subsequent microarray experiment to account for probe specific binding behaviour as part of the normalization process (see also Dennenmoser et al. more...

(Submitter supplied) The invasive marine mussel Mytilus galloprovincialis has displaced the native congener Mytilus trossulus from central and southern California, but the native species remains dominant at more northerly sites that have high levels of freshwater input. To determine the extent to which interspecific differences in physiological tolerance to low salinity might explain limits to the invasive species’ biogeography, we used an oligonucleotide microarray to compare the transcriptional responses of these two species to an acute decrease in salinity. more...

(Submitter supplied) Gene selection Microarray fabrication is described in detail in von Schalburg et al. 2005 (BMC Genomics 6:126). Selection criteria for unique Atlantic salmon (AS) and rainbow trout (RT) cDNAs for inclusion on the 16K microarray were as follows: ESTs (cDNA fragments) were assembled into contiguous sequences (contigs) by PHRAP under stringent clustering parameters (minimum score: 100; repeat stringency: 0.99). more...

(Submitter supplied) Ants provide remarkable examples of equivalent genotypes developing into divergent and discrete phenotypes. Diploid eggs can develop either into queens, which specialize in reproduction, or workers, which participate in cooperative tasks such as building the nest, collecting food, and rearing the young. In contrast, the differentiation between males and females generally depends upon whether eggs are fertilized, with fertilized (diploid) eggs giving rise to females and unfertilized (haploid) eggs giving rise to males. 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...
