Shona was awarded a BSc (Honours) in Molecular Genetics in 2014 from the University of Dundee. After completing a summer studentship funded by the BSPP studying the possibility of hybridisation between different introductions of Globodera pallida from South America, she joined the department of Nematology to undertake a PhD in biology.

Current research interests

The project is focused on finding natural resistant toward the potato cyst nematode (PCN) Globodera pallida. PCN are major plant pathogens, particularly for potato growers in Northern Europe. Withdrawal of nematicides under EU legislation (EU 91/77/EEC) has intensified the need for alternative control strategies.

The Pa1 pathotype of G. pallida was considered to have a limited distribution in a small area of Scotland and Northern Ireland. However, recent molecular characterisation of field cysts led to the conclusion that itis more widespread than originally thought, increasing the need for an effective control strategy.

Resistance from S. multidissectum PH1366, a wild relate of the domesticated S. tuberosum (potato), was found to contain the resistance gene H2 which confers high resistance to Pa1. The H2 gene is considered to be dominant and occur at a single locus, and has never been mapped to the potato genome.

The main aim of the project is to map the location of H2 onto the potato genome, followed by identifying potential putative effector targets which may trigger the H2 resistance pathway.
