  abstract = {{B}ackground: {C}offee trees ({R}ubiaceae) and tomato ({S}olanaceae) belong to the {A}sterid clade, while grapevine ({V}itaceae) belongs to the {R}osid clade. {C}offee and tomato separated from grapevine 125 million years ago, while coffee and tomato diverged 83-89 million years ago. {T}hese long periods of divergent evolution should have permitted the genomes to reorganize significantly. {S}o far, very few comparative mappings have been performed between very distantly related species belonging to different clades. {W}e report the first multiple comparison between species from {A}sterid and {R}osid clades, to examine both macro-and microsynteny relationships. {R}esults: {T}hanks to a set of 867 {COSII} markers, macrosynteny was detected between coffee, tomato and grapevine. {W}hile coffee and tomato genomes share 318 orthologous markers and 27 conserved syntenic segments ({CSS}s), coffee and grapevine also share a similar number of syntenic markers and {CSS}s: 299 and 29 respectively. {D}espite large genome macrostructure reorganization, several large chromosome segments showed outstanding macrosynteny shedding new insights into chromosome evolution between {A}sterids and {R}osids. {W}e also analyzed a sequence of 174 kb containing the ovate gene, conserved in a syntenic block between coffee, tomato and grapevine that showed a high-level of microstructure conservation. {A} higher level of conservation was observed between coffee and grapevine, both woody and long life-cycle plants, than between coffee and tomato. {O}ut of 16 coffee genes of this syntenic segment, 7 and 14 showed complete synteny between coffee and tomato or grapevine, respectively. {C}onclusions: {T}hese results show that significant conservation is found between distantly related species from the {A}sterid ({C}offea canephora and {S}olanum sp.) and {R}osid ({V}itis vinifera) clades, at the genome macrostructure and microstructure levels. {A}t the ovate locus, conservation did not decline in relation to increasing phylogenetic distance, suggesting that the time factor alone does not explain divergences. {O}ur results are considerably useful for syntenic studies between supposedly remote species for the isolation of important genes for agronomy.},
