GC content variation in the genes of the sampled species. a All positions of the codon, b first position of the codon, c second position of the codon, and d third position of the codon. Ang, angiosperms; C&G, Cycads and Ginkgo; Pin, Pinaceae; Gne, Gnetales; Con, Conifer II. Blue indicates the transferred genes in Conifer II and Gnetales and their mitochondrial homologs in other taxa, and red indicates the conserved mitochondrial genes
