Functional groups of GO terms associated with proteins resident in A. thaliana trichome and/or leaf samples. Proteins identified by proteomic analysis were filtered for their association with groups of specific GO terms (orange) and compared to proteins not associated with these GO terms (Residual, blue) concerning fold enrichment in PURE samples compared to LEAF(−) samples. Dots represent proteins identified in at least three of four measured samples whereas box plots and curves indicate the probability distribution of these proteins regarding fold enrichment. A Sulfur metabolism and detoxification. B Pectin biosynthesis and turnover. C Cell wall. D Golgi apparatus and vesicle. E Photosynthesis. Statistical significance of the difference between GO term-associated and not-associated proteins is indicated by p-values above square brackets (Wilcoxon-Mann–Whitney test). Filter criteria for GO term groups are listed in Table S2
