Figure 2From: Biologically meaningful expression profiling across species using heterologous hybridization to a cDNA microarray Detection of hybridization and regulation across phylogenetic distance. Heterologous hybridization of RNA from A. burtoni and seven other teleost species. The Y-axis defines the number of spots that hybridized above background (circles) for each hybridization experiment as well as the number of spots that showed significant (p < 0.05) up-regulation (bars) in brain RNA compared to mixed muscle RNA for each species. Colour coding of species is consistent throughout the manuscriptBack to article page
