<b>Figure 3 – HIFa gene tree rooted with two capsasporan bHLH-PAS protein sequences.</b> Clade I contains vertebrate HIF1a sequences. Clade II is composed by vertebrate HIF3a sequences. Clade III is formed by vertebrate HIF2a sequences. Clade IV represents cephalochordate HIFa genes. Clade V is composed by hemichordate HIFa sequences. Clade VI contains echinoderm HIFa genes. Clade VII represents mollusk HIFa sequences. Clade VIII is formed by brachiopods HIFa sequences. Clade IX contains phoronids HIFa genes. Clade X represents arthropods HIFa genes. Clade XI is composed by cnidarian HIFa genes. Clade XII represents placozoan HIFa genes. Black arrows and dots indicate gene duplication events. Bootstrap support values (in black) obtained from the maximum likelihood and the Bayesian posterior probabilities values (in red) shown (BP/PP). Support values &gt;80 or 0.8 are shown. Sequences in bold represent the two capsasporan bHLH-PAS proteins used to root the tree. Inset; small topology showing branch lengths with the same color scheme.
