Development of plants resistant to Papaya leaf distortion mosaic virus by intergeneric hybridization between Carica papaya and Vasconcellea cundinamarcensis
In this study, we confirmed that Vasconcellea cundinamarcensis resists Papaya leaf distortion mosaic virus (PLDMV), and used it to produce intergeneric hybrids with Carica papaya. From the cross between C. papaya and V. cundinamarcensis, we obtained 147 seeds with embryos. Though C. papaya is a monoembryonic plant, multiple embryos were observed in all 147 seeds. We produced 218 plants from 28 ...
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...
متن کاملCarica papaya MicroRNAs Are Responsive to Papaya meleira virus Infection
MicroRNAs are implicated in the response to biotic stresses. Papaya meleira virus (PMeV) is the causal agent of sticky disease, a commercially important pathology in papaya for which there are currently no resistant varieties. PMeV has a number of unusual features, such as residence in the laticifers of infected plants, and the response of the papaya to PMeV infection is not well understood. Th...
متن کاملControl 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 کاملGeneration of a Papaya Hybrid Variety with Broad-Spectrum Transgenic Resistance to Papaya ringspot virus and Papaya leaf-distortion mosaic virus
The aphid-borne potyvirus, Papaya ringspot virus (PRSV), is the major limiting factor for papaya production worldwide. Transgenic resistance conferred by the PRSV-coat protein (CP) gene and based on the mechanism of post-transcriptional gene silencing (PTGS), has become the most effective method to protecting papaya from infection by the noxious virus. The PRSV-CP transgenic lines of cultivars ...
