“…For example, the ability of transgenes to protect plants against particular viral infections is primarily related to the homology of the genes involved (Tripathi et al, 2008); this is, of course, related to their date of divergence, so a knowledge of the rate of evolutionary change of viral genes will indicate how long a particular transgene might remain effective. Finally, sequences lodged in the international databases provide a progressive and dated set of samples of the world virus populations.…”

Recent research has revealed that some plant viruses, like many animal viruses, have measurably evolving populations. Most of these viruses have single-stranded positive-sense RNA genomes, but a few have single-stranded DNA genomes. The studies show that extant populations of these viral species are only decades to centuries old. The genera in which they are placed have diverged since agriculture was invented and spread around the world during the Holocene period. We suggest that this is not mere coincidence but evidence that the conditions generated by agriculture during this era have favoured particular viruses. There is also evidence, albeit less certain, that some plant viruses, including a few shown to have measurably evolving populations, have much more ancient origins. We discuss the possible reasons for this clear discordance between short-and long-term evolutionary rate estimates and how it might result from a large timescale dependence of the evolutionary rates. We also discuss briefly why it is useful to know the rates of evolution of plant viruses.

“…These viruses are transmitted by seed, mechanical means and over 25 aphid species in a non-persistent way, a distinctive feature of the group. There are two biotypes: "P" that infects papaya and "W" that damages some members of the cucurbit family, such as watermelon (Citrullus lanatus) and melon varieties (Cucumis melon) (Tripathi et al, 2008).…”

El cultivo de papaya (Carica papaya L.) posee gran importancia económica, la cual es afectada por enfermedades causadas por virus, principalmente transmitidas por áfidos vectores. Aunque las prácticas convencionales de control de vectores parecen mantener al margen la propagación del virus, no es suficiente para evitar pérdidas en la producción. Existen desarrollos de la ingeniería genética que permiten obtener plantas resistentes a las enfermedades virales. En la presente revisión, se aborda la problemática asociada a los virus con mayor impacto para el cultivo de la papaya: Papaya ringspot potyvirus (PRSV-P) y el Papaya mosaic virus (PapMV), su variabilidad genética y las estrategias de mejoramiento genético que han permitido la generación de poblaciones resistentes a través de la recombinación de especies del género Vasconcellea con variedades comerciales de Carica papaya.

“…A basis for evaluating other prospects has been discussed . In Hawaii in the 1990s, the increasingly severe effects of papaya ringspot virus (PRSV) were addressed by development of GM papaya cultivars with resistance based on the introduction of coat protein (CP) genes from mild strains of the pathogen (Tripathi et al 2008;Fermin et al 2010).…”
