A Viroid Resembling Hop Stunt Viroid in Infected Apple Trees with Apple Scar Skin Disease in the Northeast of Iran
Abstract Background and Aims: Apple scar skin disease (ASSD) is one of the destructive diseases of pome fruits which is caused by ASSVd. Case presentation: We report molecular detection of ASSVd in symptomatic apples cv. Red Delicious with simultaneous presence of a new variant of HSVd from Khorasan Razavi province. Conclusion: This is the first report on the association of HSVd with...
متن کاملPhysicochemical Studies on Tomato Bushy Stunt Virus Variants
Tomato bushy stunt virus particles have previously been physically and chemically well characterized. Different strains, however, are known to have different host plants and symptoms, and they can be distinguished serologically. In an attempt to correlate this behavior with physicochemical properties, we have performed a comparative study on isolates of four of the main variants of this virus (...

متن کاملNucleotide sequence of the Korean strain of hop stunt viroid (HSV).
Hop stunt viroid RNA (HSV) has been detected by molecular hybridization in stunted plants of the Japanese cultivar Kirin II cultivated in Korea (1,2). For propagation, the viroid was transmitted to the wild curcarbU Benincasa Mspida which developed HSV-spedfic severe growth retardation. Isolation, purification, reverse transcription of the viroid-RNA with aid of viroid-specific primers, and seq...
متن کاملHop stunt viroid: molecular cloning and nucleotide sequence of the complete cDNA copy.
The complete cDNA of hop stunt viroid (HSV) has been cloned by the method of Okayama and Berg (Mol.Cell.Biol.2,161-170. (1982] and the complete nucleotide sequence has been established. The covalently closed circular single-stranded HSV RNA consists of 297 nucleotides. The secondary structure predicted for HSV contains 67% of its residues base-paired. The native HSV can possess an extended rod-...
