An A. thaliana genetic marker(s) was identified within the region of Brassica-Arabidopsis homology, and the BAC location of the marker was acquired using Mapviewer (www.arabidopsis.org). Or, Brassica markers within the homologous region were sequenced and the homologous A. thaliana physical position was identified using blastn. b Homology between the cited linkage group and our linkage group was determined using the relationships inferred by HU et al. 1998 . c Our B. oleracea linkage group and a B. oleracea BAC were considered homologous if both had similarity to the same position within the A. thaliana genome. d Homeology was determined using the relationships inferred by LAGERCRANTZ and LYDIATE 1996 and/or using markers shared in both studies. e The region was detected by the collinearity algorithm as collinear, but it was not significant at P < 0.05.
