Molecular characterization of two Cuban isolates of the Papaya ringspot virus by means of coat protein analysis

Abstract:

Papaya Ringspot Virus (PRSV) causes one of the most destructiva diseases in papaya (Hema and Prassad, 2004), and constitutes the main problem in this crop throughout the tropics and subtropics, limiting the production from largc áreas to a single harvest (Gonsalves, 1998). The damage can affect 100% of the production, depending on the age in which the plantation is infoctcd. Therc are many studies on the variability of this virus in several countries or rcgions. Sequences of the coat protein (CP) have been determined for differcnt viral isolates, demonstrating different levéis of variation that distinguish ihcm in origin and pathogenicity (Bateson et al, 1994; Noa, 2003). However, in Cuba, no studies have been conducted to characterize the variability of PRSV at molecular level. This knowledge is essential to understand its evolulion und epidemiology and to develop control disease strategies that allow diminish the devastating effects caused by this virus.
