a
Predominant type 1 is described in the legend to Fig. 3. Variant types 1a and 1b contain short deletions that can be ascribed to slippage between direct repeats (see text). Variant type 1c contains a 23-nt deletion from the right end of tfs3 to a site 110 nt from the 3′ end of jhp930.
b
About 20% of strains did not amplify with available primers, suggesting that they might contain other rearrangements. However, chromosomal sequencing of three such strains identified a tfs3-jhp927 connection (as in Fig. 3) in each case.
