Arsenic in roots and shoots of rice in Experiment 3

	Total As (μg g⁻¹ FW)	As(III) (μg g⁻¹ FW)	As(V) (μg g⁻¹ FW)	MAs(V) (μg g⁻¹ FW)	DMAs(V) (μg g⁻¹ FW)	As(III)%
WT root	50.5±5.1a	29.6±3.8a	12.2±0.5a	<LOD	<LOD	70.7
arsM 1 root	41.3±1.5b	22.9±1.1a	9.32±0.36b	0.13±0.00	0.10±0.01	70.6
WT shoot	4.94±2.22a	4.37±1.58a	0.49±0.25a	<LOD	<LOD	90.0
arsM 1 shoot	6.53±0.92a	5.19±1.15a	0.32±0.05a	<LOD	<LOD	94.2

Data are means ± SE (n = 4 for WT, n = 10 for arsM). Means followed by the same letter are not significantly different at P < 0.05 using One-Way ANOVA in SPSS. As, arsenic; WT, wild type, nontransgenic control; arsM 1, transgenic rice of line 1; FW, fresh weigh; SE, standard error; LOD, limit of detection.
