Function prediction can be improved by combining co-expression of orthologous gene pairs. The prediction accuracy for co-expressed genes in a species was compared to the accuracies obtained from gene associations that are conserved across two or three species considered in this study. The gain in accuracy was obtained as the ratio of the accuracy of the combined co-expression to the accuracy obtained for one species alone. The analysis was based on 697 genes (see also Figure 2) for which orthologous genes were found across all three species.
