^aGenome types 1 to 6 have the fragment order I-CeuI-ABC(DEF)G; DEF can be in any order.

^bThe orientation of fragments A and C as shown in Fig. 4.

^cGenome balance was determined from fragment sizes (Fig. 6).

^dSee the Discussion for the method used to calculate the amount off-balance.

^eThe number of strains in each type of orientation, as shown in Fig. 4.
