Scheme of Encephalitozoon cuniculi chromosome I organization. (A) The symmetrical organization of chromosome extremities, the location of the two rDNA transcription units in the subtelomeric region (gray), and the presence of a six putative CDSs duplication at the junction of the core and subtelomeric region (see Results) are illustrated. The central black trait depicts the core region composed mostly of unique genes. B represents BssHII restriction sites used for physical mapping and sequence confirmation in this study. (B) G + C percentage along the chromosome calculated in a 500-nt window with 100-nt progression increments. The highest and lowest G + C percentage are shown on the right of the panel.
