چکیده

Papaya is a favorite fruit and important industrial raw material in China. It is traditionally planted in southern China. Due to its wide uses and mystical health-related effects, papaya has been listed in fruits of high priority. Papaya ringspot virus (PRSV) is the main limitation of papaya production. PRSV infection rate reaches 100% in field in the late season of planting, which considerably reduces productivity and quality of papaya. Several research groups in China started around 1990 to develop transgenic papaya lines for resistance against PRSV, adopting pathogen-derived resistance strategy. The evaluation of resistance against PRSV and biosafety assessments with genetically modified (GM) papaya lines have been conducted in greenhouse and field. GM papaya with replicase gene from PRSV has been approved for commercial production in Guangdong province by Chinese government since 2006. In this review, we discuss 20 years research and regulatory management on transgenic papaya in China. _____________________________________________________________________________________________________________

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 ...

Gene Technology for Papaya Ringspot Virus Disease Management

Papaya (Carica papaya) is severely damaged by the papaya ringspot virus (PRSV). This review focuses on the development of PRSV resistant transgenic papaya through gene technology. The genetic diversity of PRSV depends upon geographical distribution and the influence of PRSV disease management on a sequence of PRSV isolates. The concept of pathogen-derived resistance has been employed for the de...

Complete Genome Sequence of Papaya Ringspot Virus Isolated from Genetically Modified Papaya in Hainan Island, China

The complete genome sequence (10,326 nucleotides) of a papaya ringspot virus isolate infecting genetically modified papaya in Hainan Island of China was determined through reverse transcription (RT)-PCR. The virus shares 92% nucleotide sequence identity with the isolate that is unable to infect PRSV-resistant transgenic papaya.

Generation 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 ...

Complete genome sequence of an isolate of papaya leaf distortion mosaic virus from commercialized PRSV-resistant transgenic papaya in China.

Papaya leaf distortion mosaic virus is highly destructive to commercial papaya production. Here, the complete genome sequence was determined for an isolate of papaya leaf distortion mosaic virus, designated PLDMV-DF, infecting the commercialized papaya ringspot virus (PRSV)-resistant transgenic papaya from China. Excluding the 3'-poly (A) tail, the sequence shares high sequence identity to seve...
