Figure 5From: GRASP [Genomic Resource Access for Stoichioproteomics]: comparative explorations of the atomic content of 12 Drosophila proteomes a-d biplots showing variable loading vectors for the first eight evolutionary principal component (EPC) axes describing phylogenetically independent contrasts in protein composition across the Drosophila phylogeny, i.e. summarizing evolutionary changes in proteomic composition rather than extant standing variation.
