Abstract

Tomato (Solanum lycopersicum) and coffee (Coffea canephora) belong to the sister families Solanaceae and Rubiaceae, respectively. We report herein the mapping of a common set of 257 Conserved Ortholog Set II genes in the genomes of both species. The mapped markers are well distributed across both genomes allowing the first syntenic comparison between species from these two families. The majority (75%) of the synteny blocks are short (<4 cM); however, some extend up to 50 cM. In an effort to further characterize the synteny between these two genomes, we took advantage of the available sequence for the tomato genome to show that tomato chromosome 7 is syntenic to half of the two coffee linkage groups E and F with the putative break point in t...
