Table 1

SUPPLEMENTARY TABLE 1 List of proteins isolated from endosperm tissue of etiolated castor bean seedlings, which were identified and quantified in the density-gradient fractions containing the total proteins (T1 to T4) and membrane proteins (M1 to M4). Three biological replicates were subjected to proteome analysis. Only proteins contained at least two unique peptides and a minimum of three valid values in at least one fraction (total or membrane) were classified as “identified”. Values represent the absolute abundance of the proteins calculated by the sum of the peptide signal intensities.

Table 2

SUPPLEMENTARY TABLE 2 List of castor bean proteins that have been defined as specific to peroxisomes, plastids, mitochondria, cytosol, vacuole, ER, Golgi, and nucleus based on (1) in silico prediction tools for their subcellular localization within the cell and (2) experimental data from GFP and/or MS assays of their corresponding Arabidopsis homologue using SUBA 5.0.

SUPPLEMENTARY FIGURE 1 Classification of the identified castor bean endosperm proteins from a soluble and membrane fraction enriched with peroxisomes (A), mitochondria (B), and plastids (C). The classification is based on UniProt database. Numbers in percent refer to the number of proteins that have been assigned to a certain metabolic pathway relative to the total proteins of all metabolic pathways of the respective organelle.
