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...

Many lines of genetically modified (GM) papaya (Carica papaya Linnaeus) have been developed worldwide to resist infection from various strains of papaya ringspot virus (PRSV). We found an unidentified and unauthorized GM papaya in imported processed papaya food. Transgenic vector construct that provides resistance to the PRSV strains isolated in Thailand was detected. An original and specific r...

TAXONOMY Papaya ringspot virus (PRSV) is an aphid-transmitted plant virus belonging to the genus Potyvirus, family Potyviridae, with a positive sense RNA genome. PRSV isolates belong to either one of two major strains, P or W. The P strains infect both papaya and cucurbits whereas the W strains infect only cucurbits. GEOGRAPHICAL DISTRIBUTION PRSV-P is found in all major papaya-growing areas....

Penyakit bercak bercincin pada pepaya yang disebabkan oleh Papaya ringspot virus (PRSV) dilaporkan sudah menyebar luas di Indonesia. Pemencaran penyakit ini diketahui terjadi melalui bibit tanaman terinfeksi dan serangga vektor kutudaun. Penelitian dilakukan untuk menguji efisiensi penularan PRSV dua spesies kutudaun, yaitu Aphis gossypii Myzus persicae membuktikan bahwa tidak dapat ditularkan ...

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...

Abstract: The objective of this work was to evaluate the resistance transgenic papaya populations (PTPs) Papaya ringspot virus-P (PRSV-P). 'Sunrise Solo' plants were produced with gene PRSV-P protein coat, and PRSV mechanically inoculated in greenhouse conditions. presence CP/PRSV homozygosis evaluated by polymerase chain reaction (PCR). Selected control transplanted field for agronomic evaluat...

Papaya ringspot virus (PRSV), Papaya leaf distortion mosaic virus (PLDMV), and Papaya mosaic virus (PapMV) produce similar symptoms in papaya. Each threatens commercial production of papaya on Hainan Island, China. In this study, a multiplex reverse transcription PCR assay was developed to detect simultaneously these three viruses by screening combinations of mixed primer pairs and optimizing t...

Papaya is a productive and nutritious tropical fruit. Papaya Ringspot Virus (PRSV) is the most devastating pathogen threatening papaya production worldwide. Development of transgenic resistant varieties is the most effective strategy to control this disease. However, little is known about the genome-wide functional changes induced by particle bombardment transformation. We conducted transcripto...

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...

Infeksi Papaya ringspot virus (PRSV) di Indonesia pertama kali dilaporkan pada pepaya Nangroe Aceh Darussalam tahun 2012. Sejak itu, PRSV atau penyakit bercak bercincin menyebar ke beberapa daerah Jawa, Sumatera, Bali, dan Nusa Tenggara Barat. Penelitian ini dilakukan untuk mengonfirmasi keberadaan penanaman Jawa mengetahui identitas molekulernya. Metode double antibody sandwich enzyme-linked i...
