Abstract Background Commercially available poinsettia (Euphorbia pulcherrima) varieties prevalently accumulate cyanidin derivatives and show intense red coloration. Orange-red bract color is less common. We investigated four cultivars displaying four

Testing for potato viruses is globally very important to prevent a critical shortage of potato supply. In most countries, testing is obligated by law. In Germany, seed potatoes are monitored for six viruses: PLRV, PVY, PVM, PVA, PVX and PVS. They can

Phytoplasmas are cell-wall-less bacteria that cause diseases in approximately 1,000 plant species. ‘Candidatus Phytoplasma pyri’, the causal agent of pear decline, induces various symptoms on its hosts, leading to weakening and dieback of the pla

Detecting potato viruses using direct reverse transcription quantitative PCR (DiRT-qPCR) without RNA purification: an alternative to DAS-ELISA

Autor: Johanna Stammler, Johannes Hadersdorfer, Anita Oberneder, Adolf Kellermann

Publikováno v: European Journal of Plant Pathology. 152:237-248

Virus screening is obligatory to avoid the spread of plant viruses regionally and globally. Double-antibody sandwich (DAS)-ELISA is the standard for screening potato viruses owing to its high-throughput potential, robustness, and cost–benefit ratio

We identified and quantified the main constitutive polyphenolic compounds of the leaves of seven Vitis species and of one interspecific cross, analysing leaf blades and veins separately, to spread light on the strategic localization of polyphenols in
