Transcriptome of Japanese medaka adult tissues

In order to investigate the regulatory properties that contribute to the stability and evolutionary conservation of gene expression, we focused on pleiotropic expression. To determine the number of tissues in which each gene was expressed, we collected transcriptome data for tissues of adult medaka fish (O. latipes). We selected a total of 25 different tissues to cover as much of the body as possible. A total of four replicates were obtained for each tissue, two from males and two from females. Each data was derived from one individual, not pooled. We found a moderate tendency that genes expressed in many tissues are less likely to fluctuate in expression levels among individuals and more likely to be evolutionarily conserved in expression levels.
