Fig. 2

Structure of eight transferred genes and their mitochondrial homologs in gymnosperms. Exons are indicated with boxes, and microsyntenic relationships between orthologous genes are shown with gray shadows. Introns are indicated with lines; the dashed lines indicate that the intron lengths are uncertain and the cross lines indicate that the intron lengths are too long to be shown. Numbers between boxes and lines represent phases of intron. a rps1, b rps2, c rps7, d rps10, e rps11, f rps14, g rpl2, and h sdh3
