Inhibition of PHO1 Degradation by Blocking MVB-to-Vacuole Trafficking.
The expression level of PHO1 in the root of 15-d-old wild-type (WT) (A) and pho2 (B) seedlings over 48 h of Pi recovery (250 µM KH2PO4) and E-64d treatment (50 µM) following 6 d of Pi deficiency. The bottom panel shows the protein staining on the membrane.
