Phylogenetic relationships between selected genome-sequenced Brassicaceae species relevant for the study of adaptation to extreme abiotic conditions. The phylogeny was constructed with sequences corresponding to the nuclear ribosomal ITS-1, 5.8S ribosomal RNA, and ITS-2 region identified in five species: Arabidopsis thaliana (U43225), Arabidopsis lyrata (DQ165338), Thellungiella parvula (Blast search on T. parvula transcriptome version 1.1, available at ), Thellungiella salsuginea (AF137564), and Carica papaya (AY461547), which serves as the outgroup. Alignments were performed with MAFFT, refined in BioEdit, and used for construction of the tree by neighbor joining in Mega 5. Mya, million years ago.
