Prof Wendy Harwood

Senior Scientist
Crop Genetics

Wendy leads the Crop Transformation Group which delivers a platform for genome editing and genetic modification of crop plants.

Wendy develops new methodologies and technologies to provide the platform with new capabilities and more efficient ways of working.  Current capabilities include transformation and genome editing in cereals including wheat and barley, Brassica crops, potato and tomato.

Wendy collaborates with and trains external users in these technologies.

  • Genome editing of crop plants using CRISPR
  • Agrobacterium mediated plant transformations
  • Developing new crop transformation technologies


The Wendy Harwood group is also responsible for the BRACT facility that provides crop transformation resources to the research community (

Crops of interest include wheat, barley, Brassica napus and Brassica oleracea. Efficient Agrobacterium-mediated transformation protocols have been developed for each of these crops but work continues to extend the range of genotypes that can be transformed and to further improve efficiencies.

New technologies, including genome editing using the CRISPR/cas system, have been successfully used in barley and Brassica oleracea and are being investigated in other crops. The group also has an interest in engineering tolerance to drought and salt stress in cereals.

The BRACT transformation facility helps to meet the demand for crop transformation as a research tool to verify gene function. As well as providing a full crop transformation service BRACT provides constructs, training, opportunities for collaboration and hosts visitors wishing to carry out their own transformation experiments.

Wendy is also active in public engagement and an Honorary Lecturer at the University of East Anglia.
