Miguel Nemesio-Gorriz

Research officer

Research Interests

I study tolerance in ash trees against the ash dieback pathogen, Hymenoscyphus fraxineus. The research objectives of my work are:

  • To identify tolerant ash genotypes in Ireland and to import tolerant ash genotypes from other European countries to build up a tolerant ash gene bank.
  • To study the molecular mechanisms conferring tolerance to individual ash genotypes.
  • To develop efficient propagation methods for ash material through the production of rooted cuttings and the establishment of in vitro cultures.

Current Projects

Identification and propagation of Fraxinus excelsior genotypes tolerant to ash dieback disease.
