Codon content of all protein coding genes of ten sequenced chloroplast genomes in subfamily Zingiberoideae. a amino acids and stop codons proportion in protein coding sequences of ten sequenced chloroplast genomes and b heat map analysis for codon distribution of all protein coding genes of ten sequenced chloroplast genomes. Red colour indicates higher RSCU [32, 33] values and blue colour indicates lower RSCU values
