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 کاملFirst Report of Marginal Scorch Infecting Indigowoad Root in China
During 2015, marginal scorch symptoms were detected in the production base of indigowoad rootin Hubei, China. On the basis of morphological features and 18S rDNA sequences, the pathogen was identified as Cladosporium sp. Koch’s postulates were fulfilled by pathogenicity tests on potted indigowoad root seedlings. To our knowledge, this report is the first of marginal scorch on indigowoad root ca...

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-...
