IDENTIFICATION AND CHROMOSOMAL DISTRIBUTION OF COPIA-LIKE RETROTRANSPOSON SEQUENCES IN THE COFFEE (COFFEA L.) GENOME

Identification and chromosomal distribution of copia-like retrotransposon sequences in the coffee (Coffea L.) genome

The presence of copia-like transposable elements in seven coffee (Coffea sp.) species, including the cultivated Coffea arabica, was investigated.The highly conserved domains of the reverse transcriptase (RT ) present in the copia retrotransposons were amplified by PCR using degenerated primers.Fragments of roughly 300 bp were obtained and the nucle
