In this article published online 14/06/06 and in this issue the authors have identified an error in the GenBank accession numbers in Table 2 and Figure 3. They are reproduced correctly below.

Neighbour-joining tree of Brassicaceae S-domain genes. S-domain genes of four genera of the Brassicaceae are clearly separated into groups I–III. To simplify the differentiation between the genera they are marked by dots in scales of grey. In group I SRK and SLG alleles of Brassica species and R. sativus are clustered, exclusively (dark grey/light grey dots). Putative SRK alleles of C. grandiflora (black dots) cluster within A. lyrata SRK alleles (circles) in group II. The latter were subdivided into set A and set B by Charlesworth et al (2003a) due to striking separation of subsets in all of their gene trees, which is reported recently to be correlated with different dominance classes (Prigoda et al, 2005). Interestingly, Capsella putative s-alleles appear to show the same subdivision, suggesting that this subdivision predates separation of the genera Arabidopsis and Capsella. Note, that Cgr SRK 3 is closer to Aly 13-1 than to any other Cgr SRK allele, indicating that the two genera might share an ancient allele. Group III contains the ARK 3 gene of A. thaliana and its putative orthologue in C. grandiflora and C. rubella. Phylogeny was constructed using the Kimura 2-parameter distance measure and the neighbour-joining procedure. Numbers on branches represent bootstrap values >65% and are based on 1000 replicates.

The authors apologize for any confusion caused.
