The occurrence of two strains of barley yellow mosaic virus in England
(1989-07-01)
Een aantal isolaten van het gerstegeelmozaïekvirus, afkomstig van verschillende plaatsen in Engeland, werden met elkaar vergeleken. Uit de resultaten, verkregen met ELISA, goudmerking en mechanische overdracht, kan worden ...
Stability and expression of bacterial genes in replicating geminivirus vectors in plants
(1989-04-11)
Bacterial beta-glucuronidase (gus) and neomycin phosphotransferase (neo) genes were introduced into coat protein replacement vectors based on DNA A of tomato golden mosaic virus (TGMV). Recombinant gus and neo vectors up ...
The behaviour of tomato golden mosaic virus DNA in cultured cells isolated from systemically infected tobacco leaves
(1989-03)
When callus tissue was cultured from leaf pieces taken from a Nicotiana tabacum cv. Xanthi nc. plant systemically infected with tomato golden mosaic virus (TGMV), TGMV-specific DNA persisted for up to 6 months in culture. ...
Characterisation of multimeric DNA forms associated with tomato golden mosaic virus infection
(1988-03-01)
Homodimeric and trimeric double-stranded DNA forms of both components of the genome of the geminivirus, tomato golden mosaic virus have been isolated from infected Nicotiana tabacum plants and characterised.
Gene amplification and expression in plants by a replicating geminivirus vector
(1988-01-01)
The use of plant DNA viruses as vectors for the transfer of foreign genes to plants offers two potential advantages over other, existing methods of producing transgenic plants. First, these viruses sys-temically infect ...
Systemic infection of petunia by mechanical inoculation with tomato golden mosaic virus
(1988)
Aangetoond werd dat Petunia hybrida systemisch kan worden geïnfecteerd met het 'tomato golden mosaic virus' (TGMV), een virus dat behoort tot de groep van de geminivirussen. Mechanische inoculatie van petuniaplanten met ...
Cassava latent virus specific DNAs in mosaic diseased cassava of Nigerian origin
(1987-09-01)
Het genoom van het 'cassava latent' virus (CLV), een geminivirus, bestaat uit twee cirkelvormige, enkelstrengige DNA-moleculen nl. DNA 1 (2,78 kb) en DNA 2 (2,72 kb). DNA, verkregen uit Nicotiana benthamiana-planten, die ...
Molecular characterisation of subgenomic single-stranded and double-stranded DNA forms isolated from plants infected with tomato golden mosaic virus
(1986-10-01)
A subgenomic single-stranded DNA present in particles of the geminivirus, tomato golden mosaic virus, has been shown by electron microscope heteroduplex mapping and Southern hybridisation analysis to consist of circular ...
DNA and RNA polymerase activities of nuclei and hypotonic extracts of nuclei isolated from tomato golden mosaic virus infected tobacco leaves
(1985-11-11)
Nuclei and hypotonically leached extracts of nuclei prepared from tomato golden mosaic virus (TGMV)-infected Nicotiana benthamiana leaves have been used in in vitro DNA and RNA polymerisation reactions. The synthesis of ...
