Figure 4. — General traits of plastid primary transcripts. (A) The fraction of CDSs and total genes (dashed line) found in operons in green plastids, red plastids and glacuphytes. All differences return a non-significant empiric P-value of > (see ‘Materials and Methods’ section: Empiric P-value). The total number of genes sampled in each group is given above the relevant bar. The bars show mean ± SE. (B) Operon enrichment in different gene classes. Additionally, a hypergeometric enrichment/depletion P-value was computed for each group; P < 10⁻³⁰⁰ for all groups. (C) The distribution of functional enrichment in operons for 10 000 random samples shown in contrast to the same analysis carried on randomized data (see legend). Z-score and P-value (a two-tailed Wilcoxon test) between predicted labels and shuffled labels are 2.2 and , respectively.
