Analysis of anion, total nitrogen, carbon and sulphur contents in mature Arabidopsis seeds of wild type (Wt) and sultr4;1 mutant plants. a) Seed anion content (μmol.g-1) determined by high performance ionic chromatography. b) Seed nitrogen (N), carbon (C) and sulphur (S) contents (%). Results are representative of three biological experiments. Bars represent the mean ± SE of six measurements (at least two technical replicates from each biological replicate). * and ** indicate p < 0.05 and p < 0.01, respectively.
