Incidence and Molecular-Based Identification of Papaya ringspot virus Infecting Papaya in Java
نویسندگان
چکیده
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 immunosorbent assay (DAS-ELISA) dengan antiserum spesifik digunakan mendeteksi sampel dari lapangan. Insidensi hasil deteksi DAS-ELISA Bogor, Purworejo, Kebumen, Bantul berturut-turut sebesar 59.1%, 51.4%, 84.2%, 96.2%. Identifikasi lebih lanjut reverse transcription-polymerase chain reaction menggunakan primer (PRSV326/PRSV800), dilanjutkan sikuensing DNA. Fragmen DNA berukuran 475 pb berhasil diamplifikasi lapangan analisis nukleotida menunjukkan bahwa semua terkonfirmasi homologi antarisolat berkisar antara 95.4% sampai 99.4%. Analisis filogenetika isolat-isolat berada dalam satu grup yang sama isolat PRSV-P Thailand.

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 کاملIdentification and detection of genetically modified papaya resistant to papaya ringspot virus strains in Thailand.
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...
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 کاملToxicity assessment of transgenic papaya ringspot virus of 823-2210 line papaya fruits.
The transgenic papaya is a valuable strategy for creating plants resistant to papaya ringspot virus (PRSV) infection and increasing production. This study was further performed to evaluate the comparative toxicity effects of the newly developed transgenic line of the fruits of two backcross transgenic papaya lines (2210 and 823) and one hybrid line (823-2210) and compare to their parent non-tra...
متن کاملComplete 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.
