Table 1. Developmental transcription factors in the Trichoplax genome.

Transcription factor familyGene number in TrichoplaxSubfamilies represented

The subfamily memberships of genes listed here were determined by phylogenetic analyses using neighbour-joining and parsimony with bootstrap methods for all families of transcription factors except bZip and C2H2 zinc fingers. These two groups were characterized by BLAST.
