Jennie Brierley
Senior researcher in potato pathology and diagnostics
Current research interests
My main research interests are developing the use of molecular diagnostic techniques for the detection and quantification of seed and soil-borne potato pathogens: both as a research tool to investigate the epidemiology of potato pathogens, and in supporting the management of potatoes by quantifying disease risk. By employing appropriate sampling strategies in conjunction with DNA extraction and molecular real-time PCR techniques to detect and quantify target pathogens we can validate the relationship between detectable inoculum and disease risk. Furthermore, the impact of soil-borne inoculum on disease can be investigated in conjunction with other control factors such as host resistance, crop management and chemical control options. Much of my research has been collaborative, both within the UK and internationally. Research targets have been Spongospora subterranea (powdery scab); Colletotrichum coccodes (black dot); Rhizoctonia solani AG-3 (black scurf/stem canker); Helminthosporium solani (silver scurf) and pathogenic Streptomyces spp. (common scab).
At present I am focusing on the effect of crop management practices, in particular how soil organic matter content effects the introduction and persistence of pathogens through a crop rotation. This research utilizes the Centre for Sustainable Cropping: a long-term platform for research on arable sustainability.
I am the research deliverable leader for Scottish Government RESAS workpackage RD2.1.5 "in-field detection". The aim is to improve detection of economically important pests/pathogens/diseases affecting key Scottish crops to improve decision making for growers and control recommendations leading to improved disease control.
I am a key staff member leading Integrated Pest and Disease Management (IPM) research at The James Hutton Institute. For details of ongoing IPM research areas and projects, please visit the IPM@Hutton website http://ipm.hutton.ac.uk
