La papaya (<em>Carica papaya</em>) es un frutal muy aceptado en el mercado de exportación por generar alta rentabilidad, en México se cultiva en zonas tropicales y subtropicales. El <em>Papaya ring spot virus</em> (PRSV) ocasiona la enfermedad más restrictiva de la producción de este cultivo en México y el mundo, por lo cual se evaluó la eficacia de Inhibitovir® y Virus Stop® en campo a 3 mL L-1 y 6 mL L-1 sobre incidencia, intensidad y control de la virosis, altura de planta, diámetro de tallo, número de flores y frutos, peso del fruto y rendimiento. El PRSV se detectó hasta el quinto mes después del trasplante, tiempo para que la plantación lograra un buen amarre de frutos, sin embargo, la eficacia de los inhibidores virales no tuvo diferencias significativas sobre plantas testigo infectadas con el PRSV, así como en altura de planta, diámetro de tallo, número de flores y frutos, peso del fruto y rendimiento.

Papaya Ring Spot virus (PRSV) is a devastating viral disease in papaya cultivation in Sri Lanka. It was reported that mountain papaya (Vasconcellea cundinamarcensis) exhibits resistance to PRSV. Therefore, this study was conducted to evaluate the potential resistance to PRSV in mountain papaya to be used in papaya improvement breeding programs. Carica papaya and V. Cundinamarcensis were inoculated with PRSV by mechanical inoculation technique and symptoms were evaluated visually. In order to detect the latent infection, a molecular method was developed. PRSV RNA genome segments were amplified using three sets of primers by RTPCR and an amplicon was sequenced to confirm the identity of PRSV. Functional ability of the cDNA was examined using SAND family protein gene (sand) as the reference gene. According to the results, visual symptoms were not observed in mountain papaya while standard visual symptoms appeared in Carica papaya. Three sets of primers were able to amplify the corresponding amplicons in inoculated Carica papaya and sequencing data confirmed that the amplicon was from PRSV. Negative amplification was observed in mountain papaya from the three sets of primers although sand gene amplification was observed, proving the correct functionality of cDNA. Therefore, it can be concluded that mountain papaya is likely to be resistant to PRSV.

The plant disease such as Cucumber Mosaic Virus (CMV) and Papaya Ring Spot Virus (PRSV) is a most dangerous disease that can decrease productivity and quality of the vegetable and fruit. Besides that, its also can destroy and kill those plant in long term when infected and to tackle this problem at early stages, the nanowire based biosensor application is a most reliable sensor nowadays because of advantages towards detecting biological molecule especially plant diseases.In order to dealing with tiny form of molecules such as virus is very difficult and due to the nanostructure uniqueness such as nanowire, it can be done by undergo formation of nanowire process.Result will be elaborated about how nanowire working environment in order to detecting those virus.
