Abstract
Using amplification of marker sequences with DNA from a set of distinct microdissected Vicia faba L. chromosomes covering the entire genome, we could unambiguously show that the linkage group I.B, which includes the pseudogene of legumin B4 (ψ1) and was previously ascribed to the metacentric chromosome I, actually belongs to chromosome IV. By considering the breakpoints of the translocated BKH chromosomes III and IV, even the subchromosomal position of loci LG085 and CNGC4 could be inferred. Anchoring all linkage groups to distinct faba bean chromosomes will facilitate quantitative trait locus fine mapping and gene identification using synteny, and will boost the development of efficient markers for selection in breeding programs.
