  abstract = {{B}ackground {M}yrtaceae is a family of woody trees with over 5,800 species, representing the sixth most diverse plant family. {I}t includes many economically important members distributed throughout {E}ast {A}sia, {O}ceania, and the {A}mericas, including but not limited to {E}ucalyptus grandis and {S}yzygium aromaticum. {M}ost available {M}yrtaceae genome assemblies are arranged in 11 chromosomes, and possess large variability in genome sizes, sometimes over triple the size. {A}lthough coding sequences add to this disparity, transposable elements ({TE}s) are the main contributors to genome size variation. {R}esults {I}n our research, we have characterized the landscape of {TE}s in 18 species of {M}yrtaceae. {O}ur results showed that {LTR} {C}lass {I} elements are the main contributors to genome size variations in {M}yrtaceae. {F}urthermore, specific lineages among the {G}ypsy and {C}opia superfamilies are linked to historical events of transposon activity amongst {M}yrtaceae tribes. {E}xtracted climatic and distribution data were in correlation with {TE} profiles, indicating possible lineages more sensitive to climatic conditions. {A} gene ontology over-representation analysis revealed shared biological processes influenced by {TE}s, and exclusive ones linked to different environmental responses. {L}astly, we identified high-identity sequences among many species, and performed phylogenies for horizontal transposable element transfer ({HTT}) events analysis. {A} positive {HTT} of a {C}opia/{I}vana {TE} among {S}yzygieae and {M}yrteae tribes could affect the regulation of proximal microorganism defense response genes. {C}onclusions {O}ur findings suggest that {TE}s may influence the genetic diversity present in {M}yrtaceae, where{TE} lineages contribute asymmetrically to their genomic profiles. {M}ore importantly, specific lineages are correlated with climatic variables possibly by their influence on proximal genes, a balance between genetic variation and fitness influence. {L}astly, the impact of {TE}s on microorganism defense response genes appears to be a key element in the adaptation process of {M}yrtaceae species.},
