Endogenous ALV-related retroviruses in chicken line CB

L. G. Borisenko, A. V. Rynditch

Using polymerase chain reaction and restriction length polymorphism analysis we detected ALV-related proviruses (ev loci) in DNA of inbred chicken line CB (B12/B12. All the found retroviruses (ev-1, ev-7, ev-10) may be responsible for the production of infectious and noninfectious virions. It is shown that a peak of provirus distribution is centered at CC-rich compartments of the genome (51—62 % GC).
