This treatment led to a reduction in the size of hypertrophied infection droplets and the number of cells with bacterial release (Figures 11A,B,D,E), as well as a decrease in the expression levels of the EFD, Cyp15a, and PR1 genes; in contrast, the expression of PR10 and hGSHS was upregulated in sym40-1 roots with nodules (Figure 10). The gene discussed is TMEM37; the disease is infection.
