retrotransposon

[¦re·trō·tranz′pō‚zän]
(cell and molecular biology)
A small, mobile deoxyribonucleic acid (DNA) sequence that can retrotranspose, that is, move from one genomic location to another by producing ribonucleic acid (RNA) that is transcribed by reverse transcriptase back into DNA which is then inserted at a new site.

Un fenomeno semejante se produce en la rosa (Rosa sp.) en la cual el homologo a TFL1, denominado RoKSN al tener un retrotransposon entre sus intrones, pierde su funcion y como resultado se da una floracion continua en lugar de anual como en las variedades silvestres (Iwata et al., 2012).
