Transfection of a pBR322-based, recombinant plasmid, pAV2, containing the entire adeno-associated virus (AAV) type 2 genome into human 293 cells in the presence of helper adenovirus resulted in rescue and replication of AAV to yield infectious particles. We constructed mutants of pAV2 containing deletions within the AAV sequence. We describe here the phenotypes of these AAV deletion mutants. The results can be summarized as follows. Mutants (cap-) with deletions between map positions 53 and 85

Mutants (rep-) with deletions between map positions 17 and 36 failed to rescue or replicate any AAV DNA. The rep-mutants could be complemented for replicating form DNA synthesis by a cap-mutant. This
