Resumen
Se conocen cuatro transposones de tipo mariner en hormigas: Myrmar, Mboumar, Sinvmar y Azteca. Dichos transposones se caracterizan por propagarse mediante la transferencia horizontal a las mismas o diferentes especies. Debido a la estrecha relación entre los áfidos y las hormigas se ha estudiado la presencia de estos mariners en el genoma de los áfidos.
Mediante la técnica de PCR se ha logrado amplificar el mariners similares a Myrmar en el genoma de los pulgones. Se encontraron dos variantes de tamaño de secuencias, las bandas más pequeñas han sufrido una mutación en el codón de parada, lo cual podría suponer su inactivación. También se ha logrado demostrar la presencia de transferencia horizontal mediante un estudio filogenético.
Four mariner-type transposons are known in ants: Myrmar, Mboumar, Sinvmar and Azteca. These transposons are characterized by horizontal transfer to the same or different species. Due to the close relationship between aphids and ants, the presence of these mariners in aphid genomes has been analyzed. Using the PCR technique, mariners similar to Myrmar have been amplified in some aphid genomes. Two sequence size variants were found, the smaller bands have undergone a mutation at the stop codon, which could lead to their inactivation. The presence of horizontal transfer has also been demonstrated by a phylogenetic study.
