Transcript levels of genes related to PC synthesis in the wild-type under Cd exposure in the absence or presence of hematin. Seedlings were grown in the half-strength Hoagland solution for 21 d and transferred to the same culture solution without or with 50 μM Cd in the presence of 10 μM Hematin for 1 d. Vertical bars represent standard deviation. Asterisks indicate that mean values are significantly different between the treatments and control (p < 0.05)
