Figure 4From: The evolutionary rate variation among genes of HOG-signaling pathway in yeast genomesBox plot of the d N / d S values of the HOG pathway modules in yeast species. The difference between regulator module (MAPK cascade) and other modules was significantly different (Wilcoxon rank sum test, P = 0.001154 for sensor module, P = 0.000539 for actuator module). Dots represent the dN/dS values, and black line respresent the mean value.Back to article page
