In WP1, GeneBEcon explores EU regulatory options for NGT-derived plants, detailed in a peer-reviewed article (Purnhagen et al., 2023), covering safety, adoption, and socio-economic impacts. Stakeholder engagement through Systems Mapping (SMA) and Responsible Research and Innovation (RRI) workshops is vital for understanding different perspectives. These efforts, combined with cross-project research, enhance safety data and economic analysis, leading to a decision-tree model for regulatory approvals. A real option model assesses how R&D, approval, and market phases affect breeding companies' investment decisions, and the "NGT Policy Directions" report is publicly available for policymakers.
In WP2, GeneBEcon develops a user-friendly gene editing toolbox, focusing on CRISPR/Cas applications in potato and microalgae. Research includes prime editing and homology-directed repair (HDR), with progress in plasmid and ribonucleoprotein (RNP) complex transfections to improve editing efficiency, PVY resistance, and starch quality in potato. For microalgae, advancements in screening, transfection methods, and high-value compound production are supported by bioinformatics tools to identify target genes.
In WP3, GeneBEcon applies research from WP2 to commercial potato varieties, implementing transgene-free virus resistance and improved starch quality. Greenhouse-grown potato lines with enhanced starch were harvested in Sweden, with field planting planned for 2024. The project also phenotypes potatoes for PVY resistance. For microalgae, a biosafety lab supports upscaled cultivation, and the project actively extracts high-value compounds. Trials using residual biomass as chicken feed have concluded, with ongoing meat quality assessments.
