We identify a region of mitochondrial DNA descriptive of three main groups of G. pallida present in the UK, and adopt a metagenetics approach to the sequencing and analysis of all SASA samples simultaneously. Using this approach we describe the distribution of G. pallida mitotypes across Scotland with field-scale resolution. Most fields contain a single mitotype, one fifth contain a mix of mitotypes, and less than 3 % contain all three mitotypes. Within mixed fields we were able to quantify the relative abundance of each mitotype across an order of magnitude. Local areas within mixed fields are dominated by certain mitotypes and indicate towards a complex underlying "pathoscape". Finally, we assess mitotype distribution at the level of the individual cyst, and provide evidence of "hybrids". This study provides a method for accurate, quantitative and high throughput typing of up to one thousand fields simultaneously, while revealing novel insights into the national genetic variability of an economically important plant-parasite.
