Mining Herbaria for Plant Pathogen Genomes: Back to the Future
Figure 1
The rise and fall of P. infestans lineages in the British Isles.
Frequency of genotypes over the years from the potato blight outbreaks in the British Isles (adapted from Cooke et al. (2012) [28]). Isolates of genotypes that occurred at a low frequency in a single year were grouped under the category termed ‘misc’. Two mating types of P. infestans, A1 and A2, are necessary for sexual reproduction. The shading between the bars indicates the proportion of A1- and A2-mating-type isolates, with pink referring to the A1 mating type and blue to A2. The data of 1845–1875 and 1978 were from Yoshida et al. (2013) [10] and Fry et al. (1992) [39], respectively. A template for the figure was kindly provided by Dr. David Cooke, James Hutton Institute, Dundee [28].
