| Description | Molecular phylogenetic data along with comparative genetic and cytogenetic analyses suggest that karyotype evolution in the mustard family (Brassicaceae) is characterized by the constancy of basic chromosome number x=8 in more than a third of species with reductions toward lower chromosome number in several lineages (n=8 to n=7/6/5/4). We used the Ancestral Crucifer Karyotype (ACK; n=8) consisting of eight ancestral chromosomes and 24 conserved chromosomal blocks (Schranz et al. 2006), and the comparative genetic map of Boechera stricta (n=7; Schranz et al. 2007) as a basis for the reconstruction of karyotype evolution in several n=7 species from different crucifer lineages (B. stricta: Boechereae; Myagrum perfoliatum and Glastaria glastifolia: Isatideae; Noccaea caerulescens: Noccaeeae; Thellungiella halophila: Eutremeae; Conringia orientalis: Conringieae; Calepina irregularis and Goldbachia laevigata: Calepineae; Ochthodium aegyptiacum: Sisymbrieae). |
