Fig. 3: Protein group functions with significantly different abundance in the chlorophyte vs. the streptophyte proteome.

Plotted PGs are associated with a purine homeostasis, b RNA, c photoreceptors, d photosynthesis, e lipids, f carbohydrates, and g nutrients. Functional groups are expressed as the percentage of PGs with such an annotation in each proteome. Functions were assigned with INTERPRO domains, except for phytochrome, phototropin, UVR8, and cryptochrome, which were identified by reciprocal BLASTp. The number of proteins associated with each function (PG count) is represented by the size of the symbol. All protein functions shown are significantly enriched in one proteome (p < 0.05, Log10 FC > 1, PG sum intensity > 0.1% in the sample enriched in the annotation, see “Methods” and Supplementary Fig. 4c, except for protein identified by reciprocal BLASTp). All three replicates for each sample are shown with the same symbol to ease comparison of symbol size.
