Project

PhotorActVine aims to identify Photorhabdus strains—the symbiotic bacteria of entomopathogenic nematodes of the genus Heterorhabditis—capable of controlling the fanleaf virus nematode (Xiphinema index), the vector of Grapevine Fanleaf Virus (GFLV), while simultaneously promoting grapevine growth and defense responses. By integrating microbiology, molecular biology, and plant physiology, the project seeks to deliver innovative microbial-based solutions for viticulture, reducing dependence on chemical pesticides and contributing to the EU “Farm to Fork” strategy. It is a Global Fellowship hosted by the University of Trento and the University of Chile.

• To identify Photorhabdus strains with strong nematicidal properties and adapted to grapevine root exudates.
• To investigate the protective effect of selected Photorhabdus strains in grapevine plantlets against the damage and infection caused by the fanleaf virus nematode.
• To test the capacity of Photorhabdus strains to colonize grapevine roots, promote growth, and activate defense mechanisms.

PhotorActVine will advance sustainable viticulture by providing microbial-based biocontrol strategies against grapevine pathogens and vectors. The expected outcomes include innovative prototypes of beneficial Photorhabdus strains, new insights into plant–microbe interactions, and potential industrial applications in biopesticide development. The project will contribute to reducing chemical pesticide use in viticulture, enhancing ecosystem resilience, and supporting sustainable agriculture at both scientific and socio-economic levels.
