TL;DR: Harmonised sampling and virus detection procedures including bioassays and serological and molecular methods were employed by 21 research institutions to detect PMTV in potato tubers and soil samples in 2005‐2008.
Journal ArticleDOI

TL;DR: Adapted infrastructures, technical guidelines and training are pivotal for further use and adoption of the HTS technologies in the phytosanitary framework.
Journal ArticleDOI
Sensitivity of Small RNA-Based Detection of Plant Viruses.
TL;DR: Compared with the established virus species-specific polymerase chain reaction (PCR) approach, the advantage of sRNA analysis is the detection of all tested viruses without the need for virus-specific primers or probes.
Journal ArticleDOI
Comparison of Straw Mulch, Insecticides, Mineral Oil, and Birch Extract for Control of Transmission of Potato virus Y in Seed Potato Crops
Sascha Kirchner,Lea Hiltunen,Johanna Santala,Thomas F. Döring,Jarmo Ketola,Anu Kankaala,Elina Virtanen,Jari P. T. Valkonen +7 more
TL;DR: Straw mulch use in the HG area of Finland using straw mulch may be explained by transmission of PVY early in the growing season at the time of plant emergence and the relatively low number of vector aphids.
Journal ArticleDOI
Tyrosine Phosphorylation of the Triple Gene Block Protein 3 Regulates Cell-to-Cell Movement and Protein Interactions of Potato Mop-Top Virus
TL;DR: The results suggest that tyrosine phosphorylation is a mechanism regulating the functions of plant virus movement proteins.
