| SX-2 | Shaanxi, China | A2 | S |
| SX-22 | Shaanxi, China | A2 | S |
| HN10-1 | Anhui, China | A2 | S |
| RZ4-1 | Mutant | A1 | R |
| RZ3-5 | Mutant | A1 | R |
| RZ13-2 | Mutant | A1 | R |
| XH38-10 | Mutant | A1 | R |
| XH38-13 | Mutant | A1 | R |
a
RZ4-1, RZ3-5, and RZ13-2 are zoxamide-resistant mutants generated from PCAS1 by UV-mutagenesis. XH38-10 and XH38-13 are zoxamide-resistant mutants generated from HX-1 by zoxamide adaption.
b
Isolates were only considered resistant (R) when they were able to grow on PDA plates amended with 30 µg ml−1 zoxamide.
