Figure 4From: Abandoning sex: multiple origins of asexuality in the ciliate TetrahymenaUnrooted NJ of SSU (1384 nt region) of all named species, previously barcoded strains, and putative new amicronucleate species. The tree was constructed using the Kimura 2-parameter methods and is drawn to scale. Bootstrap test (1000 replicas) percentages >50% are shown at nodes. Red: species known only from amicronucleate isolates. Black: species known only from micronucleate isolates. Fuchsia: species with both micronucleate and amicronucleate isolates. Genera: T., Tetrahymena; D., Dexiostoma; C., Colpidium; G., Glaucoma.Back to article page
