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 کاملNucleotide sequence and secondary structure of apple scar skin viroid.
The complete nucleotide sequence of apple scar skin viroid(ASSV) has been established, and a probable secondary structure is proposed. A single-stranded circular ASSV RNA consists of 330 nucleotides and can assume the rodlike conformation with extensive base-pairing characteristic of all the known viroids. ASSV shows low sequence homologies with other viroids and lacks the central conserved reg...

متن کاملfirst characterization of apple scar skin viroid from apple and pear cultivars in iran and determination of genetic diversity
apple scar skin viroid (assvd) is one of the most destructive viroid diseases in pome fruits orchards which can cause significant economic losses. symptoms of this viroid including scaring, distortion and dappling were seen in some apple orchards in east-northern of iran. sampling was carried out from apple and pear orchards. the rna was extracted by silica capture method from leaves. assvd was...
متن کاملNucleotide sequence and structural features of the group III citrus viroids.
The nucleotide sequence and secondary structure of two representative variants from the Group III citrus viroids. CVd-IIIa (297 bases) and CVd-IIIb (294 bases) were determined. The variants are related to the apple scar skin viroid (ASSVd) family. Although smaller in size than any of the ASSVd-related viroids, the central conserved region as well as most of the terminal conserved region of ASSV...
