Abundance of proteins (y axis in log2) involved in structural modifications of plastids, provision of energy, and translocation of precursors during the chloroplast-to-chromoplast transition. A, Proteins involved in the biogenesis of thylakoids and photosystems. B, Proteins involved in plastid differentiation. C, Proteins involved in plastid division. D, Proteins involved in energy and translocation. Protein abundance is expressed as a log2. The full name of the proteins is indicated in the text and in Supplemental Table S4. Abbreviations preceded by Σ correspond to the sum of several proteins harboring the same function. Individual values are given in Supplemental Table S4.
