[Changes in the composition of populations of Phytophthora infestans (Mont.) de Bary in Russia in the 1990s based on the results of mitochondrial DNA analysis].
Changes in the composition of the populations of Phytophthora infestans, the agent of late blight of potato and open-ground tomato, occurred in Russia in the early 1990s. These changes were detected via analysis of mitochondrial DNA (mtDNA) and other characteristics in 219 isolates of P. infestans. It was demonstrated that these changes were similar to those that occurred in European populations of the fungus in the early 1980s, when "old" genotypes were rapidly displaced by "new" ones. Possible causes of this phenomenon, which is related to the characteristics of the parasite's biology, and of host specialization are discussed.
