FIGURE 7 A model for B. cereus AR156 induces systemic
resistance against multiple pathogens by priming of phytoalexin
synthesis and secretion.
The root colonization of AR156 induces systemic resistance to different
pathogens in Arabidopsis . AR156 induces camalexin accumulation by
employing the transcription factor WRKY33 to regulate the expression of
genes related to camalexin synthesis. On the other hand, AR156 relies on
PEN3 and PDR12 to transfer accumulated camalexin outside the cell
allowing for protection against multiple pathogens.
