English: Codon usage bias in P. patens as compared to other selected organisms. Codon usage differs between all genes and highly expressed genes. Codonssignificantly over represented in highly expressed genes are colored dark green/marked by a (+) and significantly under represented codons are colored light blue/marked by a (–) (p-adjusted <0.05, Fisher’s exact test). (A) Codon sun adapted from Wikimedia Commons with biased codons marked in green (more abundant) or blue (less abundant). (B) Table of amino acids, codons, and codon bias in different species. Codons without bias are marked (/).
