How to cite this article. Viral inhibitors to control the Papaya ringspot virus on Carica papaya.

Papaya ringspot virus -P: Carica papaya; papaya; papaya diseases; Q VI; red Maradol; viral inhibitor. Varying genetic diversity of Papaya ringspot virus isolates from two time-separated outbreaks in Jamaica and Venezuela.

Dimitrov Todrov and I. Undoubtedly, a reduction of the symptoms caused by this virus, allowed chloroplasts to function better, reducing losses in yield and chlorophyll content, according to some potyvirus information Cabrera et al. Gutenberg Press, Tarxien, Malta. The effect of the PRSV can be evident, by oily spots on the stems, even before producing fruit rings and by an inclination of the petioles towards the soil that may reduce the photosynthetic activity of the leaves Figure 2a.

However, inoculation of the mild strain also caused pathogenesis on the papaya plants. This corroborated the idea of using this viral inhibitor as an alternative to counteract the PRSV effect along with integrated pest management IPM in sustainable agriculture. The number of lw substitutions dS was 0. El cultivo de la papaya en Los Llanos Orientales de Colombia. PRSV’s coat protein gene was inserted into highly embryogenic plant tissue by using the newly invented papzya gunanulsr led to the development of the transgenic linewhich was proven to be effective at controlling Hawaiian strains of PRSV.


Divergence and conservation of the genomic RNAs of Taiwan and Hawaii strains of papaya ringspot potyvirus. The field application of a annular antiviral formulation offers a new alternative for efficient PRSV control, which can be included fe integrated pest management.

Philippine Journal of Crop Science, 15 2— Antivirals Inhibitovir is a commercial product with viricidal action produced by Proveedora Fitozoosanitaria S.

This type infects papaya and several members of the melon family Cucurbitaceae. Characterising Cuban papaya accessions Carica papaya L. Recombinations have been reported in PRSV in almost all of its genome with the exception anularr the small region that encodes the protein 6K1.

Yields were evaluated at 9 mo after transplanting. A modified bootscan algorithm for automated identification of recombinant sequences and recombination breakpoints.

Field evaluation of transgenic papaya lines carrying the coat protein gene of Papaya ringspot virus in Taiwan. Assessment of Cuban papaya Carica papaya L.

Assessment of Cuban papaya (Carica papaya L.) accessions against ringspot

Agent for stimulating the natural defenses of plants, useful as antiviral, antibacterial, antifungal and insecticide, comprise curdian sulfate. Between andnearly all fields in the Puna region had been affected. The papaya crop occupies the ninth position of importance for fruit crops Tafur et al.

Using “clean”, virus-free seedlings for planting is of very high importance. The genomic distances for each pair of isolates were estimated by the method of two parameters lla by Kimura Kimura, Phylogeography and molecular epidemiology of Papaya ringspot virus. It is composed of an analogue base 1.


Papaya ringspot virus

Maradol roja en Cuba. These results suggest a greater evolutionary dynamic for the PRSV isolates from Campo Hermoso due to nucleotide substitutions. The Papaya ringspot virus PRSV is a very challenging virus to combat and prevents achieving a high productive potential in Carica papaya due to the lack of resistant genes in commercial papaya cultivars such as red Maradol, which originated in Cuba and extends to all America and the Caribbean.

The preventive effect of Inhibitovir applications can attenuate and reduce disease symptoms, even in those plants that were infected prior to treatment. The lowest value of diversity for the PRSV isolates from Villa del Rosario could have been caused by one of the three bottleneck events that restrict the amount papaa genetic diversity in the viral populations of plants Simmons et al.

Molecular characterization of two Cuban isolates of the Papaya ringspot virus by means of coat protein analysis. In this study, the effectiveness of a new viral inhibitor Inhibitovirapplied as a preventive and curative treatment to control PRSV was evaluated under field conditions.

This grouping could be due anklar the closeness between these two departments. The virus disease incidence was determined by calculating the symptomatic plants from the total plants sampled each treatment. Papaya Carica papaya L. Archived from the original on March 6,
