  1. The first column contains the class (bold) or subclass (indented). A plus indicates the presence of a clear member of the class or subclass. Alternatively, a minus indicates the absence of a clear member of the class or subclass. Inference of the homeodomain complement of the ancestral eukaryote is based on Derelle et al. [22].
