- Shown is the fold change expression in wild type, pdr2 and lpr1lpr2 after transfer to –Pi or the fold change expression of Pi-replete pdr2 and lpr1lpr2 plants compared to the wild-type. Red and green boxes denote genes that are significantly suppressed or induced (p ≤ 0.05, student’s t-test; 0.66 ≥ FC ≥ 1.5)
