Figure 6From: Dicyema Pax6 and Zic: tool-kit genes in a highly simplified bilaterianNJ tree based on metazoan Zic-related aa sequences. NJ tree of Zic was drawn by MEGA3 [43] by using Zic ZF core sequences (double underlined region in Fig. 4). The evolutionary distances were determined using the JTT matrix [46]. The internal labels indicate the percentage value of bootstrap test (1000 replicates). Scale bar represents evolutionary distance in substitutions/aa residue. Classification of Zic genes according to a previous study [15] is indicated by broken line and arrows.Back to article page
