Control of papaya ringspot virus in papaya: a case study.
The papaya crop is severely affected by papaya ringspot virus (PSRV) worldwide. This review focuses on efforts to control the destructiveness of the disease caused by PSRV in Hawaii, starting from the use of cross protection to parasite-derived resistance with transgenic papaya expressing the PSRV coat protein gene. A chronology of the research effort is given and related to the development of ...
متن کاملInduction of RNA-mediated resistance to papaya ringspot virus type W.
Transformation of cantaloupes with the coat protein (cp) gene of papaya ringspot virus type W (PRSV-W), Thai isolate, was used to introduce virus resistance. Binary vectors containing either the full length coat protein coding region under control of the 35S CaMV promoter(pSA1175), or the inverted-repeat of a coat protein coding region (pSA1304), were constructed and used for Agrobacterium-medi...
متن کاملThe nucleotide sequences of the 3'-terminal regions of papaya ringspot virus strains W and P.
The sequences of cDNA clones encoding most of the NIb protein, the coat protein and the 3' untranslated region of papaya ringspot virus (PRV) strains W and P have been determined. The open reading frame of P strain PRV was confirmed by amino acid analysis. Nucleotide sequence comparisons of these strains show that they share a 98.2% identity in their NIb gene regions and a 97.7% identity in the...
متن کاملPROTECTION BETWEEN STRAINS OF Papaya ringspot virus - TYPE W IN ZUCCHINI SQUASH INVOLVES COMPETITION FOR VIRAL REPLICATION SITES
A mild strain of Papaya ringspot virus type W (PRSV-W), named PRSV-W-1, has proved to be very effective in the control of the disease in zucchini squash plants under greenhouse and field conditions. The aim of this work was to obtain additional information on the protection mechanism between PRSV-W-1 and a severe homologous strain (PRSV-W-C) in Cucurbita pepo L. cv. Caserta. Protective inoculat...
متن کاملField Resistance of Coat Protein Transgenic Papaya to Papaya ringspot virus in Jamaica
In 1949, Jensen reported that the first papaya disease attributed to a virus was described in the Caribbean (14). According to Jensen, the virus, presumably Papaya ringspot virus (PRSV), was recorded by Smith in 1929 and was considered the primary reason for no large-scale cultivation of papaya (Carica papaya L.) in Jamaica. However, in the mid-1980s, papaya (also locally known as pawpaw) was p...
