In several studies we used the 5′-trnL(UAA)–trnF(GAA) region of the chloroplast DNA for phylogeographic reconstructions, gene diversity calculations and phylogenetic analyses among the generaArabidopsisandBoechera. Despite the fact that extensive gene duplications are rare within the chloroplast genome of higher plants, within several genera of the Brassicaceae the anticodon domain of thetrnF(GAA) gene exhibit extensive gene duplications with 1–12 tandemly repeated copies in close 5′-proximity of the functional gene. A recent re-examination and additional analysis oftrnL(UAA)–trnF(GAA) regions from numerous cruciferous taxa not only reveal extensivetrnF gene duplications, but also favour the hypothesis that in cruciferous taxa at least four independent phylogenetic lineages are characterized by these pseudogenes. Among these lineages there is one major clade of taxa carrying pseudogenes indicating an ancient split in crucifer evolution. In two case studies,BoecheraandArabidopsis, intra- and inter-molecular recombinations have been shown to be the reason for the reciprocal exchange of several similar motifs. However, functional constraints might favour two to three or five to six copies as shown forArabidopsisandBoechera.Herein, we compare the occurrence and distribution of pseudogene copy number in the framework of a comprehensive survey of cpDNA haplotype variation inBoechera, the former genusCardaminopsisandArabidopsis thalianaand comment on the value of such kind of mutations in phylogenetic and evolutionary reconstructions.
