- Shown is the fold change expression of selected CW modifying enzymes 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. Candidates were selected from a set of regulated genes annotated to be localized in the extracellular region (see also Additional File 6: Table S5). Red and green boxes denote significantly suppressed or induced (p ≤ 0.05, student’s t-test; 0.66 ≥ FC ≥ 1.5) genes. PME, pectin methyl esterase; EXP, expansin; EXL, expansin-like; XTH, xyloglucan endotransglucosylase/hydrolyse
