Viroid Replication, Movement, and the Host Factors Involved

open access: yesMicroorganisms
Viroids represent distinctive infectious agents composed solely of short, single-stranded, circular RNA molecules. In contrast to viruses, viroids do not encode for proteins and lack a protective coat protein.

Occurrence and molecular characterization of Potato spindle tuber viroid (PSTVd) isolates from potato plants in North China

open access: yesJournal of Integrative Agriculture, 2016
: China is the largest potato producing country worldwide, with this crop representing the fourth largest staple food crop in China. However, the steady presence of Potato spindle tuber viroid (PSTVd) over the past five decades has a significant economic

3' RNA ligase mediated rapid amplification of cDNA ends for validating viroid induced cleavage at the 3' extremity of the host mRNA [PDF]

open access: yes, 2017
: 5′ RNA ligase-mediated rapid amplification of cDNA ends (5′ RLM-RACE) is a widely-accepted method for the validation of direct cleavage of a target gene by a microRNA (miRNA) and viroid-derived small RNA (vd-sRNA).

Evidence for a Single Infectious Species of Potato Spindle Tuber Viroid

open access: yesIntervirology, 1979
Potato spindle tuber viroid (PSTV) has been separated into two electrophoretic species on polyacrylamide gels containing 8 M urea at 60 degrees. Only the slower-migrating electrophoretic form was infectious and is presumably the circular form of the molecule.

Citrus exocortis viroid causes ribosomal stress in tomato plants [PDF]

open access: yes, 2019
[EN] Viroids are naked RNAs that do not code for any known protein and yet are able to infect plants causing severe diseases. Because of their RNA nature, many studies have focused on the involvement of viroids in RNA-mediated gene silencing as being ...

Evaluation of disinfectants to prevent mechanical transmission of viruses and a viroid in greenhouse tomato production [PDF]

open access: yes, 2015
Background In recent years, a number of serious disease outbreaks caused by viruses and viroids on greenhouse tomatoes in North America have resulted in significant economic losses to growers.
