In Arabidopsis, activation of SA signaling increased the expression of PR2 and PR5 genes in a partially resistant accession (Lemarié et al., 2015), while in B. napus, PR1, PR2 and PR4, were consistently up-regulated in both host genotypes during secondary infection by P. brassicae (Galindo-Gonzalez et al., 2020). Here, TMEM37 is linked to infection.
