title: Helper-independent retrovirus vectors with Rous-associated virus type O long terminal repeats.
abstract: We have constructed nonpermuted replication-competent avian retrovirus vectors that derive from Rous sarcoma virus (S. H. Hughes, J. J. Greenhouse, C. J. Petropoulos, and P. Sutrave, J. Virol. 61:3004-3012, 1987). We describe here the construction and properties of corresponding vectors in which the long terminal repeats (LTRs) of the parental virus have been replaced by the LTRs of the endogenous chicken virus Rous-associated virus type O. The Rous-associated virus type O LTR vectors replicated approximately 1/10 as well as the parental vectors and expressed a test gene, chloramphenicol acetyltransferase, approximately 1/30 to 1/50 as well.
