In vivo dimerization of cauliflower mosaic virus DNA can explain recombination
Abstract
Pairs of heterologous cauliflower mosaic virus (CaMV) genomes cloned in pBR322, one having a defective genome and both restricted at the same pBR322 cloning site, generate recombinant molecules in infected cells when co-inoculated on plants. Analysis of the restriction pattern of the isolated recombinant CaMV DNAs indicated that the intergenomic recombination may be explained by dimerization of two heterologous CaMV molecules and transcription into a hybrid 35S RNA responsible for replication of the recombinant genomes.
