¹The identity of replicate Microbotryum isolates within each lineage are listed in parenthesis. Information on these isolates is found in Table 2

²Only a single isolate of each Lineage 1 and Lineage 2 were used in Experiment 2 and these differed from the ones used in Experiment 1 above. See text for details.
