Figure 4From: Purifying selection and birth-and-death evolution in the class II hydrophobin gene families of the ascomycete Trichoderma/HypocreaPlot of one-by-one comparisons of K a vs. K s for individual hydrophobin genes within clade "HFB1/2" (●), "HFB3" (■) and "HFB4" (▲) (for explanation of clades see Fig. 6). The dotted line indicates the position of K a /K s = 1.Back to article page
