Potato spindle tuber viroid (PSTVd) belongs to plant-pathogenic, circular, non-coding RNAs. Its propagation is accompanied by (mis)regulation of host genes and induction of pathogenesis symptoms including changes of leaf morphogenesis depending on the strength of viroid variant. We found strong genotype-dependent suppression of tomato(More)
Among computationally predicted and experimentally validated plant miRNAs, several are conserved across species boundaries in the plant kingdom. In this study, a combined experimental-in silico computational based approach was adopted for the identification and characterization of miRNAs in Humulus lupulus (hop), which is widely cultivated for use by the(More)
The use of high quality fused silica capillary nanospray tips is critical for obtaining reliable and reproducible electrospray/MS data; however, reproducible laboratory preparation of such tips is a challenging task. In this work, we report on the design and construction of low-cost grinding device assembled from 3D printed and commercially easily available(More)
Tomato multifunctional nuclease TBN1 belongs to the type I nuclease family, which plays an important role in apoptotic processes and cell senescence in plants. The newly solved structure of the N211D mutant is reported. Although the main crystal-packing motif (the formation of superhelices) is conserved, the details differ among the known structures. A(More)
Lupulin glands localized in female hop (Humulus lupulus L.) cones are valuable source of bitter acids, essential oils and polyphenols. These compounds are used in brewing industry and are important for biomedical applications. In this study we describe the potential effect of transcription factors from WRKY family in the activation of the final steps of(More)
This review focuses on the latest development of microseparation electromigration methods in capillaries and microfluidic devices coupled with MS for detection and identification of important analytes. It is a continuation of the review article on the same topic by Kleparnik (Electrophoresis 2015, 36, 159-178). A wide selection of 161 relevant articles(More)
Capillary electrophoresis coupled to mass spectrometry (CE/MS) is gaining its space among the most powerful tools in modern (bio)analytical laboratory. The most challenging instrumental aspect in CE/MS is striking the balance between the stability and reproducibility of the signal and sensitivity of the analysis. Several interface designs have been(More)
The newly developed interface-free capillary electrophoresis-nanospray/mass spectrometry system (CE-nESI/MS) was applied for rapid analysis of the cardioprotective drug dexrazoxane and its hydrolysed form ADR-925 in deproteinized blood plasma samples. The aim of this study was to test the simplest possible CE-nESI/MS instrumentation for analyses of real(More)
Surface-enhanced Raman spectroscopy (SERS) is an extremely powerful analytical tool, which not only yields information about the molecular structure of the analyte in the form of characteristic vibrational spectrum but also gives sensitivities approaching those in fluorescence spectroscopy. The SERS measurement on the microfluidic platform provides(More)
Tomato bifunctional nuclease 1 (TBN1) is a polyfunctional protein with anticancerogenic activity originally isolated as an overexpressed protein from viroid-infected tomato. Its molecular farming in plant cells could be a non-expensive source for its biotechnology preparation. So we analysed TBN1 expression in Agrobacterium-infiltrated leaf sectors of(More)
