DUSP1 and infection: The expression of these genes in non-inoculated mkp1-1 and Col-0 plants, and the rest of genotypes tested, was quite similar (Supplementary Figure S3), indicating that these genes exhibited enhanced up-regulated upon infection in mkp1-1 plants in comparison to Col-0, further corroborating the negative function of MKP1 in the control of disease resistance responses.
