Figure 2

Proposed evolutionary history of plastid-derived tRNA genes found in angiosperm mitochondrial genomes. Also shown, in bold, is one native mitochondrial tRNA gene, trnV(TAC)-mt. Open text on a branch denotes a gain of that gene, whereas strikethrough indicates the loss of that gene. Gray rectangles in the grid on the right hand side indicate presence of a given full length tRNA in each mitochondrial genome. Of the sequenced Silene mitochondrial genomes, S. latifolia was used here. Key: C = trnC(GCA)-cp, D = trnD(GTC)-cp, F = trnF(GAA)-cp, H = trnH(GTG)-cp, L = trnL(CAA)-cp, M = trnM(CAT)-cp, N = trnN(GTT)-cp, P = trnP(TGG)-cp, R = trnR(TCT)-cp, S = trnS(GGA)-cp, V-mt = trnV(TAC)-mt, W = trnW(CCA)-cp.
