Figure 3.

Gene organization around the ycf4 locus in some legumes. Triangles indicate evolutionary losses of the indicated genes. Numbers indicate the numbers of codons in accD and ycf4 genes. Psi symbols denote pseudogenes. All genes are transcribed from left to right. Fading colors denote genes that were not completely sequenced. The half-height region in rps16 represents an intron. The slash marks indicate a genomic rearrangement in T. subterraneum (Cai et al. 2008). The topology of the phylogenetic tree (not drawn to scale) is from Asmussen and Liston (1998), Wojciechowski et al. (2004), and Kenicer et al. (2005).
