Distribution of RBFs and RPs in A. thaliana. Shown is a scheme of ribosome biogenesis (left) to indicate the compartments. The compartment in which the according orthologues to yeast or human RBF or RP were found (Table S1) was used to extract the localization. Results for co-orthologues were unified and the name of the yeast (first choice) or human ortholog is depicted. The assignment of RBFs from yeast and human to different complexes was extracted from literature (for human: early = p90S, small = p40S and large = p60S).8,11 RBFs are color coded according the localization of the function in yeast (red letter: cytosol, blue: export complex, violet: nuclear, green: nucleolar; black, no assignment).
