Statistical analysis
All measurement data were expressed as mean ± SD of at least three
independent biological analyses. For the detection of differences among
the rice plants grown under different Pi conditions or rice mutants, we
used the one-way analysis of variance (ANOVA) and Tukey-Kramer’s honest
significant difference (HSD) test. All statistical analyses were
performed using the software program Origin Pro 2019 (LightStone Corp.,
Japan).
