title: Sweet potato feathery mottle potyvirus (C1 isolate) virion and RNA purification.
abstract: A procedure for the purification of a Peruvian isolate (C1) of sweet potato feathery mottle potyvirus (SPFMV) and infective RNA has been developed. The use of Hepes [N-(2-hydroxyethyl)piperazine-N'-2-ethanesulfonic acid] buffer containing urea and sodium EDTA as a base for tissue extraction and virus suspension enabled good yields of virus (35-50 mg/100 g) to be obtained from Nicotiana benthamiana L. Domin. A short RNA isolation procedure yielded infectious RNA, from which ds cDNA of nearly genome size could be obtained.
