Two cultivated species, C. arabica and C. canephora, are intensively studied while, the breeding potential and the genome composition of all the wild species remained poorly uncharacterized. Here, we report the characterization and comparison of the highly repeated transposable elements content of 11 Coffea species representatives of the natural biogeographic distribution. A total of 994 Mb from 454 reads were produced with a genome coverage ranging between 3.2 and 15.7 %. The analyses showed that highly repeated transposable elements, mainly LTR retrotransposons (LTR-RT), represent between 32 and 53 % of Coffea genomes depending on their biogeographic location and genome size. Species from West and Central Africa (Eucoffea) contained the highest LTR-RT content but with no strong variation relative to their genome size. At the opposite, for the insular species (Mascarocoffea), a strong variation of LTR-RT was observed suggesting differential dynamics of these elements in this group. Two LTR-RT lineages, SIRE and Del were clearly differentially accumulated between African and insular species, suggesting these lineages were associated to the genome divergence of Coffea species in Africa. Altogether, the information obtained in this study improves our knowledge and brings new data on the composition, the evolution and the divergence of wild Coffea genomes. specialized LTR retrotransposons Partial genome sequencing Coffea Genome size Geographic divergence AFRIQUE ZONE TROPICALE ASIE DU SUD OCEAN INDIEN ILES MADAGASCAR INDE INDONESIE 076 291 5 1979-1990 2016 1617-4615 https://www.documentation.ird.fr/hor/fdi:010068137 10.1007/s00438-016-1235-7 1617-4615 [F B010068137] https://www.documentation.ird.fr/hor/fdi:010068137 https://www.documentation.ird.fr/intranet/publi/2016/10/010068137.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-11-03 2020-09-11 fdi:010068137 fre
