Figure 5From: Mutation accumulation in TetrahymenaExamples of mutant phenotypes of Tetrahymena thermophila cells obtained as a result of the MA experiment. (A) Stereoscope images of drops containing abnormally asymmetrically dividing T. thermophila cells from bottleneck 16 (arrowheads); (B) alive cells with DNA stained with Hoechst 33342 and directly recorded under the fluorescent microscope. Images in B are selected frames from the video presented in supplementary material (Additional file 2: Video of an abnormal phenotype of Tetrahymena thermophila due to the MA experiment). The arrow points to a cell that is showing abnormal longitudinal dividing plan and presents an altered circular swimming behavior.Back to article page
