  abstract = {{R}esolving phylogenetic relationships allows the investigation of how species diversity has evolved in various ecosystems. {T}he genera {E}ntandrophragma and {K}haya consist of tree species distributed in different {A}frican biomes (lowland rain forest, dry forest and savanna, montane forest), and are suitable to examine how (single or multiple events) and when the processes of diversification led to biome transitions. {B}ased on the sequencing of plastome (p{DNA}: c. 160,000 bp), ribosomal {DNA} (r{DNA}: c. 5300 bp), and habitat characteristic data for each species, we have: (i) reconstructed phylogenetic relationships between species and estimated the divergence period between the main lineages, and (ii) reconstructed ancestral states regarding biome preferences. {T}he phylogenetic trees obtained with both markers support monophyly of the five sections of {E}ntandrophragma previously defined based on fruit and floral characters. {N}evertheless, the position of some species from the p{DNA} and r{DNA} tree topologies varied within sections. {I}n {K}haya, p{DNA} and r{DNA} show very divergent topologies, possibly due to a more recent diversification involving incomplete lineage sorting and/or recurrent hybridization events. {K}haya diversified during the {P}liocene and {P}leistocene according to both markers; whereas, according to r{DNA} data, the {E}ntandrophragma sections diverged during the early {M}iocene and species within sections diverged from the late {M}iocene to the {P}leistocene. {D}ivergence date estimates tended to be more recent using p{DNA} data. {B}iome transitions could not be reconstructed in {K}haya as the species tree remains unresolved. {C}ontrarily, three independent biome transitions were inferred in {E}ntandrophragma. {T}he first transition from rain to dry forests occurred during the {M}iocene and two other transitions were inferred during the {P}leistocene, one from rain forest to dry forest and another from rain forest to mountain forest. {O}verall, we demonstrate that multiple biome transitions occurred, starting from a rain forest biome, possibly reflecting the global trend of aridification of {A}frica throughout the {C}enozoic.},
