From: Identification and interest of molecular markers to monitor plant Pi status
Compartmental response to Pi status of shoots. a Schema of different compartments analyzed. b Free-Pi content in different aerial parts of the plant (ng Pi/mg fresh weight). c Relative gene expression of selected molecular markers in shoots. TaACT and TaGAPDH were used as housekeeping genes. All values are relative to control (0 µM Pi), which is normalized to 1. 0 and 250 design plants grown in silica:vermiculite (1:1) with Pi supply of 0 and 250 µM, respectively. Letters correspond to S (leaf Sheath), Y (Young leaves), I (Intermediate leaves) and O (Old leaves). Bars indicate means ± SD. Different letters indicate significant different means (one-way ANOVA followed by SNK test, p < 0.05, n = 6–7)
