Guo, L., Zhu, X.-Q., Hu, C.-H., and Ristaino, J. B. 2010. Genetic structure of Phytophthora infestans populations in China indicates multiple migration events. Phytopathology 100:997-1006. One hundred isolates of Phytophthora infestans collected from 10 provinces in China between 1998 and 2004 were analyzed for mating type, metalaxyl resistance, mitochondrial DNA (mtDNA) haplotype, allozyme genotype, and restriction fragment length polymorphism (RFLP) with the RG-57 probe. In addition,
