A report on the detection and management of Potato Spindle Tuber Viroid (PSTvD) in potato breeding material in Northern Ireland

Biology and Environment: Proceedings of the Royal Irish Academy, 2022
:Potato Spindle TuberViroid (PSTVd) is an infectious unencapsidated, small, circular, single-stranded RNA, that causes serious losses in infected potato and tomato plants. The pathogen has been detected in several countries worldwide, including in Europe

Size and secondary structure of potato spindle tuber viroid

Virology, 1977
Abstract The structure and size of potato spindle tuber viroid (PSTV) were investigated by electron microscopy. PSTV appears to be composed of two single-stranded RNA components of different sizes, one linear and one circular. The linear component is about four times more common than the circular.

Transmission of potato spindle tuber viroid by aphids

Netherlands Journal of Plant Pathology, 1981
Aulacorthum solani (Kaltenbach),Macrosiphum euphorbiae (Thomas) andMyzus persicae (Sulzer) were used for transmission experiments in laboratory and glasshouse. As inoculum served PSTV-containing tomato foliage and artificial diets containing purified PSTV. It is concluded thatM. euphorbiae can transmit PSTV in a non-persistent way.

Nucleotide sequence and secondary structure of potato spindle tuber viroid

Nature, 1978
The viroid of the potato spindle tuber disease (PSTV) is a covalently closed ring of 359 ribonucleotides. As a result of intramolecular base pairing, a serial arrangement of double-helical sections and internal loops form a unique rod-like secondary structure.

Characterisation of synthetic DNA probe detecting potato spindle tuber viroid

Journal of Virological Methods, 1989
Chemically synthesized DNA fragments complementary to selected regions of the potato spindle tuber viroid (PSTV) genome were cloned into Escherichia coli plasmid pUC9. One of the recombinant plasmids (pIBB4) with a 87 bp insert representing the central region of the PSTV genome (nucleotides 88 to 174) was used after labelling by nick translation for ...

Russian isolates of potato spindle tuber viroid.

Communications in agricultural and applied biological sciences, 2009
Forty PSTVd isolates collected from five regions of Russia (North-western, Central, Volga region, Northern Caucasus and the Far East) were sequenced during 2006-2008. All isolates lacked the adenine residue present at position 123 of the type strain; i.e., PSTVd-intermediate (GenBank V01465).

Detection of potato spindle tuber viroid (PSTV) in dormant potato tubers by concatameric cDNA probe

Journal of Virological Methods, 1990
The 32P-labelled concatameric insert cut out from a plasmid pSPAv6.2(+), containing 6.2 copies of a full-length PSTV, was used to detect PSTV in dormant potato tubers by dot-blot hybridisation assay. The concatameric insert probe was 4 times more sensitive than the monomeric one. This allowed the detection of 0.5 pg of viroid RNA. The sensitivity makes

Molecular characterization of Potato spindle tuber viroid in dahlia

Journal of General Plant Pathology, 2011
A new variant of Potato spindle tuber viroid (PSTVd) was detected for the first time from dahlia grown in Japan. The dahlia isolate of PSTVd formed a quasi-species and a major sequence variant consisting of 361 nucleotides in length, including five substitutions, three insertions, and one deletion, when compared to the intermediate strain from potato ...
