NPR1 and infection: Despite carrying the allele for NPR-1 215F, RC301 animals showed an enhanced resistance to infection by the bacterial pathogen P. aeruginosa (Styer et al. 2008) (Figure 1A) compared to the DA650 strain, an RC301 derivative that carries the allele for NPR-1 215F in the N2 background (de Bono and Bargmann 1998).
