  abstract = {{G}enome size variation is a fundamental feature of plant genomes and plays an important role in phenotypic diversity, ecological adaptation, and plant evolution across angiosperms. {I}n the {C}offea genus ({R}ubiaceae, 141 species/taxa), significant genome size variations have been observed. {T}here has been nearly a twofold increase between species from {E}ast and {W}est {A}frica and a notable increase from northwest to southeast {M}adagascar, resulting in geographic gradients. {P}revious studies suggest a role of {L}ong {T}erminal {R}epeat ({LTR}) retrotransposons in these variations; however, the low resolution of the data to support this hypothesis did not allow for a clear understanding of {LTR} retrotransposons dynamics within the genus. {H}ere, we present an analysis of the genomes of 22 {C}offea species mainly from {A}frica and {M}adagascar and their genome size variations within a robust phylogenetic framework. {O}ur results show that genome size and {T}ransposable {E}lements ({TE}) landscape are first structured by phylogenetic relationships, reflecting shared evolutionary history and lineage-specific {LTR} retrotransposon dynamics particularly involving the {T}ekay/{D}el, {TAT}, and {SIRE} lineages. {T}hese lineages contribute to the differentiation of phylogeographic groups, reflecting specific patterns of genomic divergence linked to species adaptation and speciation. {W}e also detected significant association between specific {TE} families and environmental variables (such as isothermality and annual precipitation). {T}hese correlations suggest that environmental factors modulate repeatome evolution and a potential adaptive role of these {TE}s. {T}hese findings highlight the importance of {TE}s in genome dynamics at the intersection of evolutionary processes and environmental adaptations and open new perspectives on their adaptive role within the {C}offea genus.},
