Figure 1From: Genome-wide identification and evolution of ATP-binding cassette transporters in the ciliate Tetrahymena thermophila: A case of functional divergence in a multigene familyUnrooted ML tree of ABC transporter NBDs in T. thermophila. Each color represents a family of ABC transporters. Genes that have an ortholog in the genome of Paramecium are marked with black panes. Bootstrap values > 50% consensus are marked with gray circles, and their sizes indicate the levels of consensus.Back to article page
