Accessory functions capable of supporting efficient recombinant AAV (rAAV) virion production in a suitable host cell are provided. The accessory functions are in the form of one or more vectors comprising a nucleotide sequence selected from the group consisting of (i) a sequence that provides adenovirus VA RNAs, (ii) an adenovirus E4 ORF6 coding region, (iii) an adenovirus E2a 72 kD coding region, and any combination of nucleotide sequences (i), (ii) and (iii), and that are capable of being transferred between cells. Methods of producing rAAV virions are also provided. The methods can be practised to produce commercially significant levels of rAAV particles without also generating significant levels of infectious helper virus or other contaminating by-products.
