RESUMO
A simplified dot-blot hybridization protocol for Potato spindle tuber viroid (PSTVd) detection in Solanaceae species is described here. The protocol uses an RNA DIG-labeled probe and a simplified extraction procedure that avoids the use of hazardous chemicals. PSTVd was detected in composite tomato leaf samples in a ratio of up to 1:15 of PSTVd-infected to non-infected tissue and in composite potato tuber samples in a ratio up to 1:5 of PSTVd-infected to non-infected tissue. In Brugmansia spp., PSTVd was detected solely in the standard sample extract preparation. The method is suitable for a reliable, large-scale sample screening especially where cost is a limiting factor.
