Nutrient concentrations in the soil-grown OsPCS1 mutant rice and the respective wild-type plants. The wild-type and OsPCS1 mutant rice were grown in pots until grain ripening under intermittent irrigated conditions. After harvest, element concentrations in leaf blade and grain (brown rice) were measured by ICP-MS. (A–D) Zn (A), Cu (B), Fe (C) and S (D) concentrations in flag leaf blade. (E–H) Zn (E), Cu (F), Fe (G) and S (H) concentrations in grain. Data represent means with the SD of two independent experiments (n = 8). Asterisks indicate significant differences between each wild type and mutant pair (*P < 0.05, **P < 0.01; t-test).
