Effect of potato spindle tuber viroid variants and infection stage on seed transmission through pollen

Letters in Applied Microbiology, 2022
Viroids are small, proteinless single‐stranded circular RNAs. In plants, they can be transmitted via infected pollen and seeds. The effectiveness of viroid transmission through pollen depends on both the viroid and host species.

Potato spindle tuber viroid (spindle tuber of potato).

2021
Abstract Several reports attribute losses in potato yield to infection by PSTVd. Le Clerg et al. (1944) determined the effect of different amounts of PSTVd on yield of marketable tubers. In 31 trials with five varieties in several states of the USA, a 4% level of infection resulted in a loss of marketable tubers of 2.6%, which includes effects ...

Detection and quantification of potato spindle tuber viroid in wild and cultivated potatoes using a new validated RT-qPCR method.

Plant Disease
Potato (Solanum tuberosum), as an internationally traded, global crop, is exposed to a wide range of diseases that cause economic losses. Economically important pathogens include oomycetes, fungi, viruses, bacteria, and viroids.

Cell-cell communication and initial population composition shape the structure of potato spindle tuber viroid quasispecies.

The Plant Cell
RNA viruses and viroids replicate with high mutation rates, forming quasispecies, population of variants centered around dominant sequences. The mechanisms governing quasispecies remain unclear.

Molecular diagnostics for detection of potato spindle tuber viroid (PSTVd) using RT-PCR

The Agrarian Scientific Journal
Potato spindle tuber viroid (PSTVd) is a pathogen that can cause great economic damage to agriculture. Potatoes infected with PSTVd are stunted in growth, and over time the plants become dwarf.
