Fig. 4From: Thirteen complete chloroplast genomes of the costaceae family: insights into genome structure, selective pressure and phylogenetic relationshipsHeat map analysis for relative synonymous codon usage (RSCU) values of all protein-coding genes of thirteen complete chloroplast genomes in the Costaceae family. Red indicates higher RSCU values and blue indicates lower RSCU values. The species in bold are sequenced in this studyBack to article page
