Abstract

Retrotransposons are the main component of plant genomes. Recent studies have revealed the complexity of their evolutionary dynamics. Here, we have identified Copia25 in Coffea canephora, a new plant retrotransposon belonging to the Ty1-Copia superfamily. In the Coffea genomes analyzed, Copia25 is present in relatively low copy numbers and transcribed. Similarity sequence searches and PCR analyses show that this retrotransposon with LTRs (Long Terminal Repeats) is widely distributed among the Rubiaceae family and that it is also present in other distantly related species belonging to Asterids, Rosids and monocots. A particular situation is the high sequence identity found between the Copia25 sequences of Musa, a monocot, and Ixora, a dicot species (Rubiaceae). Our results reveal the complexity of the evolutionary dynamics of the ancient element Copia25 in angiosperm, involving several processes including sequence conservation, rapid turnover, stochastic losses and horizontal transfer.
