From: The complete mitochondrial genome of Sinojackia microcarpa: evolutionary insights and gene transfer
Distribution of transfer RNA (tRNA) genes in plant mitochondrial genomes. The white boxes indicate that the gene is absent or lost in the mitochondrial genome. Yellow and green boxes indicate mitochondrial tRNA genes and plastid-derived tRNA genes, respectively, with one copy existing in each mitochondrial genome. The numbers represent the copy numbers in the mitochondrial genome
