Because these responses in Bd3‐1, such as SA‐dependent disease resistance and rapid prevention of pathogen infection, are hallmarks of defense responses mediated by R proteins, these data suggest that the relationship between R. solani isolate MAFF305230 and Bd3‐1 (and probably also Tek‐3) qualifies as an incompatible plant–pathogen interaction. This evidence concerns the gene TCN1 and infection.
