Durable disease resistance

This theme principally revolves around investigating and deploying durable disease resistance into economically important crops. Underpinning this is the desire to understand the interaction between plants and pathogens. By using this information to study the mechanisms of resistance, it will advance our scientific knowledge to improve crop production in a sustainable way.


Key areas of research:

  • Resistance mechanisms
  • Evolution of host resistance
  • Resistance strategies

The nature of resistance to Neonectria ditissima in apple species

The fungal pathogen, Neonectria ditissima, is the causal agent of European canker in apple. Most modern apple varieties are susceptible and there is poor chemical control of canker of trees due to its systemic nature of the disease. It has … Continue Reading

Developing durable disease resistance to bacterial canker of cherry

Bacterial canker, caused by Pseudomonas syringae is a major disease of cherry, for which there is no effective control. This project aims to use bioinformatic and experimental approaches to understand the host adaptation and pathogenicity of P. syringae and elucidate … Continue Reading

Genomics of Phytophthora fragariae

The work aims to apply sequencing technologies and ‘-omics’ approaches to understand the cause of the differences in the ability of isolates of the oomycete pathogen Phytophthora fragariae to cause disease in varieties of the cultivated strawberry Fragaria × ananassa. … Continue Reading

IDRIS- Improving Disease Resistance in Strawberry

Project description: This work, a 5 year BBSRC LINK project applies effectoromics and comparative genomics techniques to identify pathogen effectors and map resistance QTL for the oomycete pathogens, Phytophthora cactorum and Phytophthora fragariae in Fragaria spp. Race specific markers will … Continue Reading

Resistance to powdery mildew in cultivated strawberry

EMR, Driscoll’s Genetics Ltd and Berry Gardens growers are working in an industry-led project to identify and characterise the genetic basis of strawberry powdery mildew resistance in the octoploid cultivated strawberry. Members of the Harrison lab and the strawberry breeding … Continue Reading

Developing robustness to biotic stress in fruit crops

Strawberries contribute to a nutritious and healthy diet and are an important UK crop. Increasing restrictions in chemical disease controls mean that existing varieties will soon be unsuitable for sustainable production in the soil. Verticillium wilt is one of the … Continue Reading
