High resolution map of eggplant (Solanum melongena) reveals extensive chromosome rearrangement in domesticated members of the Solanaceae

Abstract : A linkage map of eggplant was constructed for an interspecific F-2 population derived from a cross between Solanum linnaeanum MM195 and S. melongena MM738. The map contains 400 AFLP(A (R)) (amplified fragment length polymorphism), 348 RFLP (restriction fragment length polymorphism) and 116 COSII (conserved ortholog set) markers. The 864 mapped markers encompass 12 linkage groups, span 1,518 cM and are spaced at an average interval of 1.8 cM. Use of orthologous markers allowed confirmation of the established syntenic relationships between eggplant and tomato chromosomes and helped delineate the nature of the 33 chromosomal rearrangements and 11 transpositions distinguishing the two species. This genetic map provides a 2- to 3-fold improvement in marker density compared to previously published interspecific maps. Because the interspecific mapping population is rich in morphological variation, this greater genome saturation will be useful for QTL (quantitative trait locus) analyses. The recent release of the tomato genome sequence will provide additional opportunities for exploiting this map for comparative genomics and crop improvement.
