Abstract：
:Photobiotin was used to prepare biotinylated, nonradioactive nucleic acid probes for the detection of the RNA of barley yellow dwarf virus (BYDV) in plant extracts. A 1.7-kb cDNA of the PAV isolate of BYDV in the plasmid pUC8 vector was biotinylated and then used intact or as sonicated double-stranded DNA fragments. Simple methods were developed for the preparation of partially purified nucleic acid extracts of cereals and their spotting, after formaldehyde treatment, onto nitrocellulose membranes. After hybridization, biotin-labelled DNA bound to BYDV RNA on the nitrocellulose was detected with an avidin-alkaline phosphatase conjugate. BYDV RNA was readily detected with a sensitivity similar to that found with the same probe labelled with 32P by nick translation. Healthy plant extracts gave colourless spots.
