G-TwYST is operated by 8 project partners:


The senior scientists involved in G-Twyst have been asked to declare their interests and activities in the field of GMOs and food safety research on a voluntary basis.



The Stiftung Tierärztliche Hochschule Hannover, University of Veterinary Medicine Hannover (TiHo), is a university foundation with approx. 1300 staff members, 30% of them being scientists, and consists of six clinics, 18 institutes and 5 specialized research centers. The main research interests of the TiHo are infection medicine, neuroscience, animal health and food quality as well as clinical research. Institute for Food Toxicology and Analytical Chemistry (IFT): The main research areas of IFT are the elucidation of the mechanisms of toxicity of chemicals present in foods of animal and plant origin, the development of analytical-chemical methods to study the biological activities of food constituents and contaminants as well as the development of alternative methods to animal testing. At the present time the IFT is concretely working on the role of compounds that are formed during the heating of foods in colorectal cancer development (heterocyclic aromatic amines and endogenously formed nitroso compounds), the development of methods to assess the toxicity of pesticide mixtures present on and in foods and the development of methods to test the reproductive toxicity and carcinogenicity in vitro. Moreover, IFT has a modern animal housing facility, in which chronic toxicity and carcinogenicity studies in rats are performed.


TiHo is coordinator of the project and leader of work package 5: evaluation of the scientific value of and broader societal issues associated with animal feeding trials and risk assessment of genetically modified organisms. TiHo  also contributes to WP3, WP4, WP6 and WP7.

The Julius Kühn-Institut, Federal Research Centre for Cultivated Plants (JKI) is both a Federal Authority in its own right and a Federal Research Centre under the jurisdiction of the Federal Ministry of Food and Agriculture (BMEL). The 16 institutes within JKI are involved in several fields of plant research (basic to applied). JKI has branches at 11 locations in Germany with approx. 1200 staff members including about 250 scientists.
The Institute for Biosafety in Plant Biotechnology (SB) focuses on the assessment of, and research on new biotechnological methods applied to plants, including genetic engineering and introduction of novel crops. It is involved in the authorization of the deliberate release and placing on the market of GM organisms. The own research supports the scientific advice provided to the BMEL. SB is also partner in the EU-funded projects GRACE (coordinator) and Pre Sto GMO Era-Net establishing the links with G-TwYST.

The Data Processing Unit (DV) manages the IT services of the JKI with the following tasks: planning, development and maintenance of central IT systems, network and communication infrastructure, IT services for research and management. It participates in IT-related research projects in the domains of plant protection, plant genetic resources, and bioinformatics.

JKI supports the coordinator and is responsible for establishment of the flow of information about feeding trials in all work packages and linking G-TwYST, GRACE, GMO 90plus and PreSto GMO ERA-Net. JKI coordinates logistics for plant, feed material, and external services and hosts the web application CADIMA for the integration and dissemination of study results.

logo CRAG.jpg

The Centre for Research in Agricultural Genomics (CRAG) is a public consortium that comprises research groups from Spanish Research Council (CSIC), the Institute for Food and Agricultural Research and Technology (IRTA), and the Universities Autonomous of Barcelona (UAB) and Barcelona (UB).CRAG is specialized in the study of characteristics of interest in plants and farm animal species, combining basic and applied research in model and crop species and applying molecular and genetic approaches for breeding and food production. The institute has a very strong tradition in molecular biology studies on plants, especially maize, rice, and potato. It has a service of GMO analysis (ENGL member), in which frame we developed GMO detection and quantification methods and worked on coexistence or detection of unauthorised GMOs. Towards GMO safety assessment, we studied the stability of transgene DNA loci and mRNA transcripts and as well as unintended effects of the transgene in plants using transcriptomics (both, with Affymetrix microarrays and 454Roche sequencer) and proteomics approaches, using GM maize and rice.

The University of Girona (UDG), third party in this project, has educational and research tasks, in particular in the food and agricultural areas. Areas of research of interest for this project: GMO safety assessment area, specifically using omics approaches; coexistence of GM and conventional crops in agricultural fields; design and biotechnological production of antimicrobial peptides with plant protection applications.


The Fundació Mas Badia (FMB), collaborator in this project, is an agricultural experimental station intended to guide and enhance agriculture in the region through research and communication with farmers. Its board has a broad representation of institutions from the agricultural sector. FMB has a centre with 30 ha agricultural area and works on extensive cultivation, crop protection, fruit growing, irrigation and agro-meteorology.
In close geographical proximity, CRAG, UDG and FMB have a large experience in collaborating together to develop research projects in the field of GMO.

CRAG and UDG (third party) are involved in the coordination of the supply of GM and conventional maize grain to prepare rat diets (work package 2); CRAG will carry out, together with UDG, the omics characterisation of the plant material used to prepare feed.

The Slovak Medical University (SZU) has long-standing experience in the area of environmental health research with multidisciplinary know-how and combination of experimental and clinical research. The most important research part of the SZU - Centre of Excellence is involved in the original research in environmental health, food safety and health and occupational health. SZU coordinated the EU-funded FP5 projects PCB RISK and HEAR NAS and is/was involved in the FP6 projects ENVIRISK, HENVINET, INTARESE, HEIMTSA and FP7 Grace, NanoTEST, NanoImpactNet and QualityNano. Activities are conducted in compliance with GLP regulations.

SZU leads work package 3 and performs the combined chronic toxicity / carcinogenicity study with GM maize NK603, a 90-day feeding trial with GM maize NK603, as well as a carcinogenicity study with GM maize MON810.
