Retrotransposons Mobility in Eight Pure Lines of Laying Chickens

Abstract

Abstract In this study, retrotransposons mobility in eight pure lines of the domestic chicken (Gallus gallus domesticus) was analysed using IRAP-PCR (Inter-retrotransposon amplification polymorphism Polymerase Chain Reaction) method. Polymorphism rates were detected as 0–78% in Copia-like, 0–73% in Nikita, 0–60% in SIRE, and 0–38 in Sukkula in Rhode Island Red, Barred Rock, Colombian Rock, Line-54, Black Line, Blue Line, Brown Line, and Maroon Line chickens. In silico analyses presented that Blue Line with Line-54 and Barred Rock with Colombian Rock are closely related regarding these four retrotransposons. These horizontally transferred plant-specific retrotransposons may affect changes in the pure-line chicken genome.
