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 technologies and the pressing need to control PSRV in Hawaii. The development of commercial virus… Expand
Development of genetically engineered resistant papaya for papaya ringspot virus in a timely manner: a comprehensive and successful approach.
TLDR
This chapter presents the experimental steps involved in the development of transgenic papaya, including transgene construction, transformation, and analysis for virus resistance of the transformed papaya. Expand
Transgenic papaya in Hawaii and beyond
TLDR
A field trial to test a PRSV-resistant transgenic papaya had started in 1992, and by 1995 the 'Rainbow' and 'SunUp' transgenic cultivars had been developed, and these cultivars were commercialized in 1998. Expand
Current status of the transgenic approach for control of Papaya ringspot virus.
TLDR
It is suggested that a chimeric construct targeting multiple viral genes including the gene determining viral virulence and gene silencing suppression, such as the HC-Pro gene of a potyvirus, may minimize the chance of emergence of a super virus in overcoming the transgenic resistance. Expand
Transgenic Papaya: A Case for Managing Risks of Papaya ringspot virus in Hawaii
TLDR
resistant transgenic papaya, an F1 hybrid from a cross of the transgenic SunUp, and nontransgenic Kapoho are now widely planted and have helped save the papaya industry. Expand
Transgenic Papaya: A Case Study on the Theoretical and Practical Application of Virus Resistance
TLDR
A snapshot of the development and successful deployment of genetically engineered transgenic papaya to control PRSV in the Hawaiian papaya industry is provided. Expand
Agbiotechnology: Costs and Benefits of Genetically Modified Papaya
TLDR
The success in Hawaii, the difficulty in Taiwan, and the hurdle in Thailand for application of GM papaya are addressed in terms of costs and benefits. Expand
Papaya ring spot disease management: A review
TLDR
In countries like India where there are legal restrictions on research on genetically modified (GM) food crops, introgression of the PRSV-P resistance gene into C. papaya from its wild relatives (species of Vasconcellea) is the one of the optimistic option available with. Expand
Transgene-mediated resistance to Papaya ringspot virus: challenges and solutions
TLDR
The focus is on factors affecting transgenic resistance in papaya and the attempt to explain why the Hawaiian scenario of complete and durable resistance has not been replicated in other regions. Expand
Gene Technology for Papaya Ringspot Virus Disease Management
TLDR
The development of PRSV-resistant papaya via post-transcriptional gene silencing is a promising technology forPRSV disease management and has no harmful effects on human health. Expand
Papaya ringspot virus-P: overcoming limitations of resistance breeding in Carica papaya L.
TLDR
The approach was refined with the advancement of knowledge of genetic mapping of C. papaya vis-a-vis other species of the genus Vasconcellea with the help of molecular taxonomy and raised hope for development of PRSV-P-resistant hybrids with commercially acceptable fruit quality in the near future.

Watermelon mosaic virus 1 and 2 in Queensland cucurbit crops
TLDR
Physical properties of these WMV isolates showed them to be similar to those reported elsewhere, but there were some distinctive host reactions for the WMV-2 isolates, and methods for the identification of each on differential hosts and by serology were shown to be effective. Expand
Resistance of Transgenic Hybrid Squash ZW-20 Expressing the Coat Protein Genes of Zucchini Yellow Mosaic Virus and Watermelon Mosaic Virus 2 to Mixed Infections by Both Potyviruses
TLDR
Transgenic yellow crookneck squash line ZW-20B is a hybrid of commercial quality, and its high level of resistance to ZYMV and WMV 2 should enable the production of yellow summer squash in areas where both potyviruses are prevalent. Expand
Mechanisms of Pathogen-Derived Resistance to Viruses in Transgenic Plants.
TLDR
The major emphasis is on the mechanisms of pathogen-derived resistance rather than on the practicality of using this technology for crop improvement, because these mechanisms have proven difficult to unravel. Expand
