A putative primer for the replication of cauliflower mosaic virus by reverse transcription is virion‐associated

Abstract
We have isolated, from a cauliflower mosaic virus (CaMV) preparation, an RNA species (75 nucleotides) covalently linked to the 5′‐end of the CaMV DNA fragment (sa‐DNA) which is complementary to the CaMV 35 S RNA transcript 5′‐end. Site‐specific cleavage located a unique m7G residue in the RNA moiety of sa‐DNA suggesting that it is host cell tRNAmet i sa‐DNA is reminiscent of retrovirus ‘strong‐stop“ DNA and is evidence fo the reverse transcription model of CaMV replication.
