The genes were ordered in each experiment according to the clusters presented in . The significant increase in coherency of the response with the increase of environmental pressure by is apparent in the image. Expression profiles of genes belonging to glycolysis (), histidine () and purine () pathways. Note the emergence of highly correlated patterns of transcription owing to the environmental pressure in the lower panel. A given functional module simultaneously contains correlated and anti-correlated trajectories
