As lesion mimic mutants often have an accompanying resistance phenotype [15], [16] we hypothesized that snl6-FN plants may show enhanced susceptibility to Xoo. Indeed, snl6-FN lines show longer water-soaked lesions after infection with Xoo and support greater populations of Xoo cells than NH1ox plants (Figure 2A and 2B), indicating that Snl6 is required for NH1-mediated resistance. Here, FN1 is linked to infection.
