Figure 6. A proposed model for the ASR1/ASR5-STAR1 promoter interaction.

Figure 6.

ASR1 and ASR5 are auto-regulated. In response to Al, ASR5 increase their transcript levels by an unknown pathway, regulates positively ASR1 and together with ART1, increase STAR1/STAR2 complex to mask Al binding sites in the cell wall.
