Characterization of four endogenous viral genes in semi-congenic lines of meat chickens.
Restriction fragment length polymorphism analyses were used to examine endogenous viral genes (ev genes or ALVE genes) of the avian leukosis viral (ALV) family in semi-congenic lines of meat chickens. The Generation 6 lines examined in this study were semi-congenic in that each contained birds with either zero or with one ALVE gene in hemizygous state plus some solitary long terminal repeat (LTR) elements. Using four restriction enzymes on chicken genomic DNA and two probes, one representing the entire ALV retroviral genome and one with only a small part plus the LTR, four ALVE genes were characterized. Each seemed to be complete with no detectable deletions. None appeared to be similar to known ALVE genes of White Leghorns, whereas two of the four may be the same as ALVE genes reported by others in White Plymouth Rock chickens.
