Abstract

A new slow growing, nonpapillate, homothallic Phytophthora species with quite large oogonia isolated from leaf blight of kudzu (Pueraria lobata) in Toyama and Ishikawa district of Japan in 2005 which could not be assigned to existing taxa. The isolates were re-examined in the light of morphological study and multi-locus phylogenetic analysis including six nuclear regions ie. rDNA internal transcribed spacer (ITS), rDNA large sub-unit (LSU), translation elongation factor 1-alpha (EF1-alpha), heat shock protein 90, 60 S ribosomal protein L10 and beta-tubulin and one mitochondrial gene, cytochrome c oxidase (cox)I. The species differs morphologically from its closely related Phytophthora species by its characteristic obturbinate and distorted sporangium with external proliferation, aplerotic oospore, predominantly amphigynous and intercalary antheridia, presence of catenulate hyphal swellings, higher optimum growth temperature and relatively slower growth rates. The unique characteristic is the germination of zoospore inside the sporangia. In the multi-locus phylogenetic analysis based on seven loci, they form a distinct monophyletic group within clade 7 with strong bootstrap support. The result of morphological and phylogenetic analysis support that the isolates represent a new species Phytophthora puerariae sp. nov.
