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 کاملHop stunt viroid (HSVd) sequence variants from Prunus species: evidence for recombination between HSVd isolates.
Hop stunt viroid (HSVd) is able to infect a number of herbaceous and woody hosts, such as grapevine, Citrus or Prunus plants. Previous phylogenetic analyses have suggested the existence of three major groups of HSVd isolates (plum-type, hop-type and citrus-type). The fact that these groups often contain isolates from only a limited number of isolation hosts prompted the suggestion that group-di...

apple scar skin disease (assd) is one of the destructive diseases of pome fruits which is caused by assvd. 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. this is the first report on the association of hsvd with assvd in apple trees showing merely symptoms of apple dapple on the fruit.
متن کاملRegulation of pathogenicity in hop stunt viroid-related group II citrus viroids.
Nucleotide sequences were determined for two hop stunt viroid-related Group II citrus viroids characterized as either a cachexia disease non-pathogenic variant (CVd-IIa) or a pathogenic variant (CVd-IIb). Sequence identity between the two variants of 95.6% indicated a conserved genome with the principal region of nucleotide difference clustered in the variable (V) domain. Full-length viroid RT-...
