As described, the interaction of R. pseudostellariae with F. oxysporum caused the repression of the seven defense-related genes (PAL3, CH5, CH1, PR10, PRSTH-21, PR1a, and PR4), via a mechanism to overcome plant defense responses and thereby promoting the process of infection in plants (Peix et al., 2001). This evidence concerns the gene SUCO and infection.
