Contents of Zn and phytic acid in LLZ and Os-lpa-XS110–1 under different Zn conditions. a Zn content in the brown rice; b Phytic acid content in the brown rice; c Molar ratio of phytic acid to Zn in the brown rice. The results are presented as mean ± SEM. Asterisks represent statistically significant differences between LLZ and Os-lpa-XS110–1 (n = 4; *P < 0.05; **P < 0.01)
