Scientific Reports, 2017 It is well established that viroid derived small RNA (vd-sRNA) induces RNA silencing of endogenous mRNA. However, it remains not clear how exactly viroid infections can lead to severe symptom induction given the fact that fewer vd-sRNAs binding the ...

Genetics and Molecular Biology, 2006 We report the nucleotide sequences of three citrus viroids belonging to three different genera: Citrus exocortis viroid (CEVd), Hop stunt viroid (HSVd) and Citrus viroid-III (CVd-III) isolated from a single natural infected Citrus reticulata var ...

Acta Horticulturae, 2011 With a genome composed of a small (246-401 nt), single-stranded, circular RNA, viroids are a special class of replicons infecting plants, including some ornamentals, in which they may induce specific diseases. In striking contrast to plant viruses, which encode proteins mediating their own replication and movement, viroids depend on host factors for ...

Occurrence Status of Five Apple Virus and Viroid in Korea
Research in Plant Disease, 2020 The investigation of the infection rate of domestic apple orchards by four types of apple viruses (Apple chlorotic leaf spot virus [ACLSV], Apple stem pitting virus [ASPV], Apple stem grooving virus [ASGV], Apple mosaic virus [ApMV]) and one type of ...

Self-assembly Controls Self-cleavage of HHR from ASBVd (−): a Combined SANS and Modeling Study [PDF]
, 2016 International audienceIn the Avocado Sunblotch Viroid (ASBVd: 249-nt) from the Avsunviroidae family, a symmetric rolling-circle replication operates through an autocatalytic mechanism mediated by hammerhead ribozymes (HHR) embedded in both polarity ...

Insights Into Potato Spindle Tuber Viroid Quasi-Species From Infection to Disease
Frontiers in Microbiology, 2020 Viroids are non-coding RNA plant pathogens that are characterized by their possession of a high mutation level. Although the sequence heterogeneity in viroid infected plants is well understood, shifts in viroid population dynamics due to mutations over ...

Proceedings of the National Academy of Sciences, 1982 Viroids are small "naked" infectious RNA molecules that are pathogens of higher plants. The potato spindle tuber viroid (PSTV) is composed of a covalently closed circular RNA molecule containing 359 ribonucleotides. The properties of PSTV were compared with those of the scrapie agent, which causes a degenerative neurological disease in animals.

Modes of Viroid Transmission [PDF]
Cells, 2022 Studies on the ways in which viroids are transmitted are important for understanding their epidemiology and for developing effective control measures for viroid diseases. Viroids may be spread via vegetative propagules, mechanical damage, seed, pollen, or biological vectors.

Nucleotide bias of DCL and AGO in plant anti-virus gene silencing [PDF]
, 2010 Plant Dicer-like (DCL) and Argonaute (AGO) are the key enzymes involved in anti-virus post-transcriptional gene silencing (AV-PTGS). Here we show that AV-PTGS exhibited nucleotide preference by calculating a relative AV-PTGS efficiency on processing ...
