Figure 3.

Arsenic and mineral nutrient contents in wild-type (WT) and d10 and d17 mutant plants exposed to different concentrations of sodium arsenate (Na₂AsO₄; 0, 125 and 250 μM As^V). The contents of arsenic (a), phosphorus (P) (b), zinc (Zn) (c), calcium (Ca) (d) and magnesium (Mg) (e) in rice shoots were determined on day 3 of As^V treatments. Represented numerical data are the means with standard errors (n = 4 biological repeats). Significant differences (p < 0.05) among the treatments are denoted by distinct alphabetical letters according to a least significant difference test. DW, dry weight; ND, not detected.
