Abstract

Three solanaceous are considered of great economic importance: potato (Solanum tuberosum), tomato (Solanum lycopersicum) and sweet pepper (Capsicum annuum). Tomato chlorosis virus - ToCV (Genus Crinivirus) has recently been identified infecting these three species in producing areas in Brazil. There is few information on the epidemiology of ToCV involving these solanaceous, which are often grown near to each other. Therefore, this work aims to study the interaction among potato, tomato and sweet pepper in the epidemiology of ToCV. Furthermore, studies will be carried out to optimize the molecular method for detection of this virus in potato. Potato, tomato and sweet pepper plants infected with ToCV will be used as sources of inoculum for acquisition of the virus by the whitefly Bemisia tabaci biotype B and subsequent transmission to the same species, in tests with and without choice option. For the optimization of RT-PCR for detection of ToCV in potato, total RNA extracted from different tissues (young, intermediate, old leaves and tubers) will be analyzed separately. Different methods of total RNA extraction for RT-PCR will also be analyzed. (AU)
