From: Sultr4;1 mutant seeds of Arabidopsis have an enhanced sulphate content and modified proteome suggesting metabolic adaptations to altered sulphate compartmentalization

Figure 4

Proteome variations detected in mature seeds of Sultr4;1. a) A representative proteome map from mature Arabidopsis seeds is shown. Circles and stars represent proteins whose level respectively increased and decreased in sultr4;1 mutant seeds compared to wild-type. The spots #11, 27, 32, 40, 45, 83, 122, 134, 137, 187 and 226 were identified by using the proteome reference maps from Gallardo et al. [25, 26] and Rajjou et al. [27]. The other proteins were identified by mass spectrometry in the present study (see Additional file 7). Colors indicate the functional category of proteins according to the ontological classification of Bevan et al. [29] (see Figure 4b, Additional files 5 and 6). Example of abundance variations for spots 2, 38, 40, 97, 122 and 239 in wild-type and sultr4;1 mutant are shown. Each bar represents the mean ± SE of at least three biological replicates. * and ** indicate p < 0.05 and p < 0.01 respectively (variance analysis). b) Distribution of proteins whose abundance varied significantly in each functional category. Within each class, the number of proteins whose abundance vary versus the total number of proteins identified is indicated. See Additional file 4 for a complete annotation of the proteome reference map.
