摘要：

Diseases caused by potato virus X (PVX) are of significant agronomic importance, and early detection is vital. Biotinylated DNA probes were prepared by random‐primed labelling from cDNA inserts and used for the detection of PVX in crude extracts of infected tubers. The minimum detection level in these extracts is in the order of femtograms of PVX RNA. Comparison with ELISA showed that the hybridization method is 100–250 times more sensitive. Probes prepared by this method are highly specific for target RNA even in crude tuber extracts. Copyright © 1990, Wiley Blackwell. All rights reserved
