ViroiDoc Project

About the project

ViroiDoc is an international, multidisciplinary doctoral network focused on understanding and tackling viroids - tiny RNA pathogens that threaten global crop production. Aligned with the European Green Deal and the Farm-to-Fork strategy, the project supports sustainable agriculture and food security.
Through its consortium of academic and industry partners, ViroiDoc trains 10 doctoral candidates (MSCA fellows) in an interdisciplinary and cross-sectoral environment, preparing them for careers in research, biotechnology, and agricultural innovation.

Research focus areas

Viroids are the smallest known plant pathogens consisting of a single circular RNA molecule. Annually, they are responsible for crop losses in the millions of euros worldwide. These losses impact both crop yields and quality. The international trade and climate change have enabled the spread of viroids to new geographical regions and hosts, thereby threatening global food security.

Viroid-like RNAs have only recently been discovered outside the plant kingdom using advanced sequencing technologies and computational analyses. Their exact functions remain largely unknown. Some viroid-like RNAs are infectious and capable of autonomous replication. For instance, a few viroid-like RNAs have been found to successfully infect fungi and human oral and gut bacteria.

ViroiDoc Consortium

ViroiDoc brings together 22 academic and industrial partners from 11 countries across Europe and the Americas. The consortium includes nine core beneficiaries with expertise in molecular biology, genetics, biotechnology, and bioinformatics, all working toward improved viroid diagnosis and plant disease control.

Their research is supported by a strong network of associated partners, including leading EU research laboratories, academic institutions in Argentina and the USA, and five industry partners specializing in plant breeding, diagnostics, plant protection, and consulting. More about partners.

The ViroiDoc consortium brings together researchers with complementary expertise across the following areas:

Basic research

Molecular biology, biotechnology, genetics, bioinformatics.

Applied sciences

Nano- and sensor technologies.

Innovation development

Horizon Europe MSCA

Marie Skłodowska-Curie Actions (MSCA) under the EU research framework programme Horizon Europe support excellence in research and innovation. The MSCA funds doctoral and postdoctoral programmes and collaborative research and innovation projects with various calls. ViroiDoc project is funded through the Horizon Europe – MSCA Doctoral Networks. 

About MSCA

The programme promotes the uptake of the principles of the Charter for Researchers and the objectives of the European framework for research careers by improving recruitment and working conditions and setting standards for researchers. The MSCA also make a notable contribution to the reform of research assessment systems, promoting a broad definition of excellence and diverse career paths, in line with the European Commission’s commitment to the process initiated by the Coalition for Advancing Research Assessment (CoARA).

About MSCA Doctoral Networks Action

Doctoral Networks implement programmes to recruit and train doctoral candidates in academia and other sectors, including industry, businesses, and public administrations. The scheme includes the development of joint degrees, including a possible European degree, and industrial doctorates, training doctoral candidates in academia and other sectors, including industry and business.
