From: Identification and interest of molecular markers to monitor plant Pi status
Growth of wheat plants grown during 30 days in three different soils. a Pi content in soils after Olsen extraction (Pi Olsen) or after Pi diffusion in anion exchange membranes (RAE) n = 2–3. b Shoot fresh weight (g). c Free-Pi content in shoots (ng Pi/mg fresh weight). d Relative gene expression analyses of selected molecular markers. TaACT and TaGAPDH were used as housekeeping genes. 0 design plants grown in silica:vermiculite (1:1) with Pi supply of 0 µM. Bars indicate means ± SD. Different letters indicate significantly different means (one-way ANOVA followed by SNK test, p < 0.05, n = 6–7)
