Age dependence of the copia transposition rate is positively associated with copia transcript abundance in a Drosophila melanogaster isogenic line.
In males of an inbred Drosophila melanogaster line (2b), a significant age dependence of the transposition rate of the retrotransposon copia was noted. Among males of seven different age groups, the lowest transposition rate was detected in 12- to 15-day-old males, and the highest transposition rates were observed in 1- to 3- and in 24- to 27-day-old males: rates of 0.36 +/- 0.07, 1.09 +/- 0.20 and 117 +/- 0.27 transpositions per generation per gamete, respectively, were measured.
