Sulfate and total sulfur contents in leaves of wild-type and transgenic Arabidopsis plants. A, Rosette leaves of three Arabidopsis wild-type plants (black bars) and three individuals of each independent transgenic plant line with reduced mitochondrial SAT activity (gray bars) were analyzed for sulfate contents. FW, Fresh weight. B, The total sulfur content in dried rosette leaves of 8-week-old wild-type plants (black bars) and the amiSAT3 lines 4 and 5 (gray bars) was analyzed using an elemental analyzer (n = 4). Error bars indicate sd, and asterisks mark significant differences using the unpaired t test. DW, Dry weight.
