Trinucleotide frequencies and codon usage. a) The averaged Physcomitrella codon fraction usage measured as percentage of the total amount of counted codons is shown as grey diamonds, including a margin of 2× average absolute deviation (AAD, error bars), in comparison with Arabidopsis (yellow circles). Significantly deviating codons of the sequence subsets are presented as colored circles, namely retained genes (blue), paralogs (red) and orthologs (green). b) The effective number of codons (enc) for Physcomitrella (green) and Arabidopsis (yellow) as a range distribution scatter plot (y axis: % of analysed genes) and as averaged values (horizontal bar chart; error bars: standard deviation).
