Figure 4From: History of myxozoan character evolution on the basis of rDNA and EF-2 dataHypothetical evolution of ancestral morphotypes and their bionomical characters. Schematic drawing summarises evolution of myxospore morphology based on the SSU rDNA phylogeny and character evolution analysis. Rectangles, circles and asterisks show the switches of bionomical characters. GB - gall bladder, UB - urinary bladder, RT - renal tubules, MUSCL - muscles, INT - intestine, HIST - histozoic, POLYSP - polysporic. Dashed lines indicate two alternative branches leading to Ceratomyxa shasta.Back to article page
