Comparative evolutionary analysis of chalcone synthase and alcohol dehydrogenase loci in Arabidopsis, Arabis, and related genera (Brassicaceae).
We analyzed sequence variation for chalcone synthase (Chs) and alcohol dehydrogenase (Adh) loci in 28 species in the genera Arabidopsis and Arabis and related taxa from tribe Arabideae. Chs was
Chromosome triplication found across the tribe Brassiceae.
Phylogenetic relationships based on the chloroplast 5'-trnL (UAA)-trnF(GAA) region and estimated divergence times based on sequence data of the chalcone synthase gene are congruent with comparative painting data and place Calepina, Conringia, and Sisymbrium outside the clade of Brassiceae species with triplicated genomes.
Molecular systematics of the Brassicaceae: evidence from coding plastidic matK and nuclear Chs sequences.
It is concluded that tribe Brassiceae might be the only monophyletic group of the traditional tribes, and tribes Lepidieae, Arabideae, and Sisymbrieae are not monophylets.
Molecular phylogenetics, temporal diversification, and principles of evolution in the mustard family (Brassicaceae).
The resulting tree, the largest in number of genera and markers sampled to date and covering the whole family in a representative way, provides important insights into the evolution of the family on a broad scale.
Toward a global phylogeny of the Brassicaceae.
Results from parsimony ratchet and Bayesian analyses recovered little support for the backbone of the phylogeny, suggesting that many lineages of Brassicaceae have undergone rapid radiations that may ultimately be difficult to resolve with any single locus.
Poorly known relatives of Arabidopsis thaliana.

Genetic consequences of Pleistocene range shifts: contrast between the Arctic, the Alps and the East African mountains
The genetic structure observed corresponded to the expectations based on the environmental history of the different regions, and the fragmented structure in the European and African mountains indicated that A. alpina disperses little among established populations.
