From: Arabidopsis PHOSPHATE TRANSPORTER1 genes PHT1;8 and PHT1;9 are involved in root-to-shoot translocation of orthophosphate

Figure 7

Effect of the Atpht1;9–1 mutation on the P-responsiveness of transcripts from Pi-responsive genes, including those encoding known P signaling components. Transcript abundance in 44-day-old Atpht1;9–1 plants is expressed relative to that in WT plants grown under the same conditions (∆∆Ct values). The transcript patterns were examined in both roots (A) and shoots (B). Plants were grown in nutrient solution containing 250 μM Pi for 30 d, and then transferred to solution containing 250 μM Pi or no added Pi for 14 d before harvest. Each panel shows the comparison made using plants grown on nutrient solution containing sufficient Pi or no Pi. Values are means ± S.D. (n = 3 biological replicates of 12 plants each grown at separate times).
