Comparison of Arabidopsis tissue-specific genes as defined by transcriptomic or proteomic approaches. (A) Number of distinct and common tissue-specific genes defined by transcriptome (151 genes, Schmid et al., 2005) or by proteome (469 genes, Baerenfaller et al., 2008) studies in the “leaf,” “root,” “flower,” and “seed” samples. Only samples commonly used in the two studies (i.e., flower, leaves, root, and seed) were compared. (B) Number of seed-specific genes identified by transcriptome (Schmid et al., 2005), proteome (Baerenfaller et al., 2008) or both approaches.
