Nudeotkle Sequence of Cucumber Pale Fruit Virotd: Homology to Hop Stunt Viroid
Double stranded cDNA of cucumber pale fruit viroid (CPFV) has been cloned by the method of Okayama and Berg (Mol.Cell.Biol.2,161-170 (1982)) and the complete nucleotide sequence was established. The covalently closed circular molecules of single-stranded CPFV RNA consists of 303 nucleotides. The nucleotide sequence of CPFV was compared with the previously established sequence of hop stunt viroi...

متن کاملGlobal Transcriptomic Changes Induced by Infection of Cucumber (Cucumis sativus L.) with Mild and Severe Variants of Hop Stunt Viroid
Fifteen years after transfer to hops, hop stunt viroid-grapevine (HSVd-g) was replaced by HSVd-hop (HSVd-h), a sequence variant that contains changes at five different positions. HSVd-g54 is a laboratory mutant derived from HSVd-g that differs from its progenitor by a single G to A substitution at position 54. While infection by HSVd-h induces only mild stunting in cucumber (Cucumis sativus L.)...
