Gene expression of root development related genes in response to Pi deficiency. a-b TaE2f; c-d TaSERK1; e-f TaEXPB23 in the roots and shoots of CS and KN199 after 7 days’ treatment on Pi-sufficient (+Pi, white bars) or Pi-deficient (−Pi, black bars) solution. Data represent mean values ± SD (n = 3), and different letters indicate significant differences (p < 0.05) using the least significant difference multiple range test
