Abstract

Summary A novel single stranded DNA of approximately 1350 nucleotides in length has been identified associated with infected yellow vein mosaic croton termed as DNA- β, requires the begmovirus for replication, encapsidation, insect transmission and movement in plants. It exhibit the properties of a satellite molecule having approximately 80 nucleotides conserved region which has been suggested to be important in trans-replication of DNA- β by the begmoviruses rep, possibly containing cryptic rep binding sites. In the present study βC1genes encoded by DNA betasatellite were targeted in transient assay for stable transformation to develop resistance against geminivirus.
