Summary

This multi-partner EU project POnTE is exploring the genetics, biology, epidemiology, vector ecology and economic impacts of four pathosystems that threatens strategic crops and forestry in the EU including new and exotic Phytophthoras.

Research objectives

The aim is to gain greater understanding about the risk of introduction and potential impact of Phytophthora pathogens that threaten Europe, with Forest Research involved in the part of the project related to emerging diseases of forests.

Specific objectives are to:

• Survey and monitoring for the presence of Phytophthoras in forest and in natural ecosystems in the UK.
• Gain knowledge about the pathogenicity and host range of new or Phytophthora species recently arrived in Europe.
• Assess species diversity of Phytophthora species in environmental samples, contrasting traditional isolation techniques with Illumina sequencing.
• Develop new q-PCR markers for detection of new Phytophthora species.
• Investigate spread of Phytophthoras from nurseries into the wider environment, via recent and new plantings. This work will complement the LWEC PHYTO-THREATS project
• Develop a basic scheme for an international protocol to help in producing Phytophthora free stock, thereby minimizing opportunities for spread into the wider environment.

Results so far

The project is in its early stages and no results are yet available.

Status

POnTE started the 1^st of November 2015 and will run for 48 months.

Focus on Hymenoscyphus fraxineus

Summary

This multi-partner EU project POnTE is exploring the genetics, biology, epidemiology, vector ecology and economic impacts of four pathosystems that threatens strategic crops and forestry in the EU including the highly invasive ash dieback pathogen Hymenoscyphus fraxineus.

Research Objectives

The aim is to gain a greater understanding about the impact and possible mitigation of the ash dieback pathogen H. fraxineus as it impacts on ash populations across Europe.

Specific objectives include:

• Survey and monitoring of Hymenoscyphus fraxineus in the UK
• Compare isolates by morphological, physiological and molecular analysis.
• Analyse population differences in Hymenoscyphus fraxineus using sequence analysis (GBS) and MultiLocus Variable number of tandem analysis (MLVA). This will complement ongoing research on the ecological genetics of H. fraxineus
• Provide pure cultures and infected tissues of Hymenoscyphus fraxineus for the validation of new protocols.
• Develop a reliable method for the detection of viable Hymenoscyphus fraxineus in seeds.
• Assess the potential of hot water treatment as a method of eradicating H. fraxineus from ash seeds.
• Contribute to the mass screening trial to identify inherent resistance in UK ash trees to H. fraxineus.

Findings and Recommendations

The project is in its early stages and no results are yet available.
