451. Wild and globally traded ornamental aquatic plants harbor diverse plant viruses, including notable crop pathogensLana Vogrinec, Katarina Bačnik, Martina Bačič, Nataša Mehle, Aimee R. Fowkes, Živa Lengar, Valerie Harju, Ian Adams, Adrian Fox, Denis Kutnjak, 2025, izvirni znanstveni članek Povzetek: Background Aquatic plants play key roles in ecosystems, serving as primary producers and providing habitat for other aquatic life. While many are ecologically important, some invasive species, often introduced through the ornamental plant trade, pose threats to various aquatic ecosystems. Although viral infections have been documented to some extent in aquatic crops, the viral diversity in wild and ornamental aquatic plants remains largely unexplored. Investigating the viral communities of aquatic plants is important, as their direct contact with water allows for the potential long-distance transmission of stable viruses released from infected individuals. Invasive aquatic plants exacerbate this issue by introducing novel microbes, including viruses, to new regions, increasing the potential threat to native plant populations. Results Here, we investigated the viral communities of diverse aquatic plants by mining publicly available transcriptome data of 79 wild aquatic species and sequencing the RNA from 14 plant species (some of them of different ornamental varieties), sourced from hobby aquascaping stores. Plant viruses from various families were detected in taxonomically diverse aquatic plants, ranging from algae to angiosperms. Alongside sequences of known crop pathogens, such as turnip yellows virus, cucumber mosaic virus, and lettuce chlorosis virus, we identified contigs of putative novel viral species belonging to several plant-infecting viral families. Most notably, we discovered sequences of known and novel begomoviruses, which may be causing observed ornamental phenotypes in two different aquatic plants. Further, we identified a novel potyvirus that appears to be globally present in multiple ornamental plants from the genus Sagittaria. We detected it in three plants sourced from online stores in Slovenia, as well as six plants intercepted during the import process into the UK. Conclusions Our findings expand on the so far limited knowledge of aquatic plant viruses, revealing known and putative novel plant viral species across diverse aquatic plant taxa. The detection of crop viruses, including regulated pathogens, in ornamental aquatic plants highlights the risks associated with their unregulated global trade. Further research into viruses of aquatic plants may provide insights into their role in ecosystems as well as their potential impact on agriculture.

455. Multiplex quantification of 19 GM soybean lines using digital PCRAmadej Jelenčič, Dejan Štebih, Tina Demšar, David Dobnik, 2026, samostojni znanstveni sestavek ali poglavje v monografski publikaciji Povzetek: The European Union (EU) imposes strict regulations on the presence of genetically modified (GM) material in food and feed, requiring thorough testing of samples for various GM lines. Although traditional quantitative real-time PCR (qPCR) methods are sensitive and robust, they are not cost-effective for managing large numbers of GM events due to their limited multiplexing capabilities. Conversely, digital PCR (dPCR) is capable of robust quantitative multiplexing in addition to other benefits such as absolute quantification and better tolerance of PCR inhibitors. In this context, we present a protocol for multiplex quantification of 19 GM soybean lines using dPCR as an improvement over the currently used simplex qPCR approach. This method enables simple and robust quantification of common GM soybean lines with a relatively low number of reactions.

460. In vitro evaluation of electrochemotherapy combined with sotorasib in pancreatic carcinoma cell lines harboring distinct kras mutationsTanja Jesenko, Maša Omerzel, Tina Živič, Gregor Serša, Maja Čemažar, 2025, izvirni znanstveni članek Povzetek: Pancreatic cancer is among the deadliest malignancies, with limited treatment options and poor prognosis. Novel strategies are therefore urgently needed. Sotorasib, a KRAS G12C-specific inhibitor, offers targeted treatment for a small subset of patients with this mutation. Electrochemotherapy (ECT), which enhances the cytotoxicity of chemotherapeutic agents through electroporation-induced membrane permeabilization, has shown promise in various tumor types, including deep-seated malignancies such as pancreatic cancer. Combining ECT with sotorasib may potentiate antitumor effects in KRAS G12C-mutated pancreatic cancer; however, preclinical data on such combinations are lacking. This proof-of-concept study evaluated the cytotoxic effects of ECT using bleomycin (BLM) or cisplatin (CDDP) in combination with sotorasib in KRAS G12C-mutated MIA PaCa-2 and KRAS G12D-mutated PANC-1 pancreatic cancer cell lines. ECT alone significantly reduced cell viability, particularly in MIA PaCa-2 cells, where electric pulses induced approximately 75% cell death. Combining ECT with sotorasib resulted in an additive effect on KRAS G12C-mutated MIA PaCa-2 cells, though no synergy was observed, likely due to the high intrinsic sensitivity to electric pulses. These results support the potential of combining physical and molecular therapies in a subset of pancreatic cancer patients and lay the groundwork for further in vivo studies to optimize treatment parameters and explore clinical translatability.
