Subcellular targeting results for selected proteins identified from this proteomic study
chpt, Chloroplast; cyt, cytosol; perox, peroxisome; nuc, nucleus; pm, plasma membrane; TMs, transmembrane domains. Numbers in parentheses (on the scale of 0 to 1) are probabilities for the prediction of respective transmembrane domains by the plant membrane protein database Aramemnon (http://aramemnon.botanik.uni-koeln.de/); values greater than 0.7 were considered to be positive.
