a
Genotypes in rows 1 to 6 exhibited significantly reduced susceptibility, while genotypes in rows 7 to 13 were not significantly different after silencing. Order of genotypes is identical to that in Figure 5.
b
Plants were inoculated with Bgh isolate 5874 (AVRa1, AVRa6). The rates of severity of Bgh infection are presented as 0 to 4, indicating levels of sporulation from completely resistant (0) to completely susceptible (4).
