  • Title: Replication of the cauliflower mosaic virus: role and stability of the cloned delta 3 discontinuity sequence.
    Author: Pietrzak M, Hohn T.
    Journal: Gene; 1985; 33(2):169-79. PubMed ID: 3996915.
    Abstract:
    A fragment of cauliflower mosaic virus (CaMV) DNA, containing delta 3, one of the three discontinuity sequences, was cloned in various ways into CaMV DNA deleted for the delta 3 sequence. The series of constructions was monitored for the appearance of the typical single-strand (ss) discontinuity after hybrid CaMV replication in plants. The delta 3 discontinuity was observed only if the orientation of inserted DNA sequence was the same as in the wild-type virus. Long polylinker sequences used for insertion of the fragment into cloned viral DNA, affected the stability of the insert in progeny viral DNA in plants by acting as recombination targets.
