Mitochondrial localized proteins that are related to glycerolipid biosynthesis in Arabidopsis leaves (L-mito) and cell cultures (C-mito). A, Glycerophospholipid, (B) glyceroglycolipid, and (C) phosphoinositide metabolism. Proteins identified and/or localized in mitochondria were labeled (i) dark gray: proteins identified in the proteomic analysis of this study and also predicted to localize in mitochondria, (ii) light gray: proteins identified in the proteomic analysis of this study in mitochondria but predicted to localize in other organelles, (iii) bold font: exclusively localized in mitochondria and (iv) italic font: only identified in one of the mitochondrial populations. Heat maps visualize the protein abundance of three independent experiments of mitochondria purified from leaves and cell cultures from Figure 1 and listed in Supplemental Tables 1 and 3. The heat map colors represent mean intensity values according to the color map on the top right-hand side. The absolute values represented by each color map are deposited in Supplemental Table 1. Predicted protein localization was based on The Arabidopsis Information Resource (TAIR; www.arabidopsis.org) and the Subcellular localization database for Arabidopsis proteins (SUBAcon; www.suba.live).
