Expression levels of TaPHT1s and TaPHO1 in roots and shoots of the wild type and tapho2 mutant plants grown in nutrient solutions containing 10 μM Pi (low P) and 200 μM Pi (high P) levels.
(a) TaPHT1.1/1.9; (b) TaPHT1.2; (c) TaPHT1.10; (d) TaPHT1.3/4; (e) TaPHT1.6; (f) TaPHO1. LP and HP indicate low P and high P treatment, respectively. Error bars indicate SE (n = 5). Asterisks indicate the significance of differences between wild type and tapho2 mutants as determined by Student’s t test analysis: *P < 0.05.
