  abstract = {{T}he wild species of the {C}offea genus present a very wide morphological, genetic, and biochemical diversity. {W}ild species are recognized more resistant to diseases, pests, and environmental variations than the two species currently cultivated worldwide: {C}. arabica ({A}rabica) and {C}. canephora ({R}obusta). {C}onsequently, wild species are now considered as a crucial resource for adapting cultivated coffee trees to climate change. {W}ithin the {C}offea genus, 79 wild species are native to the {I}ndian {O}cean islands of {C}omoros, {M}ayotte, {M}auritius, {R}eunion and {M}adagascar, out of a total of 141 taxa worldwide. {A}mong them, a group of 9 species called "{B}aracoffea" are particularly atypical in their morphology and adaptation to the sandy soils of the dry deciduous forests of western {M}adagascar. {H}ere, we have attempted to shed light on the evolutionary history of three {B}aracoffea species: {C}. ambongensis, {C}. boinensis and {C}. bissetiae by analyzing their chloroplast and nuclear genomes. {W}e assembled the complete chloroplast genomes de novo and extracted 28,800 {SNP} ({S}ingle {N}ucleotide {P}olymorphism) markers from the nuclear genomes. {T}hese data were used for phylogenetic analysis of {B}aracoffea with {C}offea species from {M}adagascar and {A}frica. {O}ur new data support the monophyletic origin of {B}aracoffea within the {C}offea of {M}adagascar, but also reveal a divergence with a sister clade of four species: {C}. augagneurii, {C}. ratsimamangae, {C}. pervilleana and {C}. {M}cphersonii (also called {C}. vohemarensis), belonging to the {S}ubterminal botanical series and living in dry or humid forests of northern {M}adagascar. {B}ased on a bioclimatic analysis, our work suggests that {B}aracoffea may have diverged from a group of {M}alagasy {C}offea from northern {M}adagascar and adapted to the specific dry climate and low rainfall of western {M}adagascar. {T}he genomic data generated in the course of this work will contribute to the understanding of the adaptation mechanisms of these particularly singular species.},
