Codon and repeat analyses of the 62 sampled plastomes from the Coffeeae alliance. a Codon usage biases of the plastome of Alibertia edulis, a representative species from the Coffeeae alliance clade. The values at the top of each stack indicate the frequency of use of each amino acid, while the bars (colour-coded) represent the relative values of synonymous codon usage for each codon. b The percentage distribution of five types of repeats. c Chord diagram showing the number and type of SSRs
