Summary Genome colinearity has been studied for two closely related diploid species of the Brassicaceae family, Arabidopsis thaliana and Capsella rubella . Markers mapping to chromosome 4 of A. thaliana were found on two linkage groups in Capsella and colinear segments spanning more than 10 c m were revealed. Detailed analysis of a 60 kbp region in A. thaliana and its counterpart in C. rubella showed virtually complete conservation of gene repertoire, order and orientation. The comparison of orthologous genes revealed very similar exon–intron structures and sequence identities of 90% or more were found for exon sequences. This extensive genome colinearity at the genetic and molecular level allows the efficient transfer of data from the well‐studied A. thaliana genome to other species in the Brassicaceae family, substantially facilitating genome analysis studies for species of this family.
