Abstract:
:We have developed a plant- Escherichia coli pASV shuttle vector from the essential elements of the Ageratum yellow vein virus (AYVV). The geminivirus vector contains the AYVV genome with the coat-protein deletion, the E. coli vector backbone of pUC19, a unique cloning site and gene expression cassettes for plant selection and reporter gene activity. The replication of pASV vectors was compared in Nicotiana benthamiana and N. tabacum BY2 cells, and the latter were found to be suitable for long-term maintenance of the vectors in culture. The vector DNA was detected at regular intervals by PCR, beta-glucuronidase expression analysis and plasmid rescue during a 4-month culture period. A novel methylation-based PCR assay was carried out to show de novo replication for pASV-derived vectors in 2-month-old tobacco BY2 cell lines. This is the first report of the extrachromosomal replication of monopartite begomovirus with stability and foreign gene expression in long-term cell cultures.
