First Report of Potato Spindle Tuber Viroid in Costa Rica

Plant Disease, 1999
During 1997 to 1998, symptoms of leaf roll, dwarfism, chlorosis, and occasional leaf necrosis were observed on Solanum tuberosum in several plots in Cartago, the principal potato-production region of Costa Rica. Because of the known association between potato leafroll virus (PLRV) and viroids (1) and previous reports of PLRV in Costa Rica, the ...

RNAi-Mediated Down-Regulation of Dicer-Like 2 and 4 Changes the Response of 'Moneymaker' Tomato to Potato Spindle Tuber Viroid Infection from Tolerance to Lethal Systemic Necrosis, Accompanied by Up-Regulation of miR398, 398a-3p and Production of Excessive Amount of Reactive Oxygen Species. [PDF]

Viruses, 2019
To examine the role of RNA silencing in plant defenses against viroids, a Dicer-like 2 and 4 (DCL2&4)–double knockdown transgenic tomato plant line, 72E, was created.

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

Journal 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

Expression of the transcription factor encoding gene StTCP23 in potato plants infected with the tuber spindle viroid

Труды по прикладной ботанике, генетике и селекции, 2023
Background The potato spindle tuber viroid (PSTVd) is the smallest of all known potato pathogens. PSTVd is a circular, single-stranded RNA molecule that does not code for proteins.

Three Cycles of Continuous Propagation of a Severe PSTVd Strain NicTr-3 in Solanum lycopersicum cv. Rutgers Resulted in Its Attenuation and Very Mild Disease Symptoms in Potato

Agronomy, 2023
Potato spindle tuber viroid (PSTVd) is a small infectious non-coding circular RNA causing diseases of important crops, including tomato and potato. The symptoms vary from mild to severe depending on the viroid strain, the host plant variety, and the ...

Evolutionarily New Solanaceous DCL2 Family Members Acquire Functions in Tomato. [PDF]

Mol Plant Pathol
This work demonstrated the expansion of functional Dicer‐like 2 gene family members in the Solanaceae family. ABSTRACT RNA silencing is one of the major defence activities against viral pathogens in plants. Silencing signals are initiated by Dicer‐like proteins (DCLs) to generate viral‐derived small RNAs (sRNAs).
