|a An emerging soilborne disease resembling Phytophthora stem rot was observed on mung bean plants grown in Anhui, China. To identify the causal agent, diseased plants and soil samples from 13 fields were collected to isolate the pathogen. Twenty-two Phytophthora isolates were recovered from the samples and detailed identification was conducted. Based on morphological and molecular characterizations, all of the isolates were consistently identified as P. vignae. Phylogenetic analysis using eight nuclear loci sequences of the internal transcribed spacer region, rRNA gene large subunit, a partial sequence of the β-tubulin gene, translation elongation factor 1α, 60S ribosomal protein L10, the enolase gene, heat shock protein 90, and triose phosphate isomerase/glyceraldehyde-3-phosphate dehydrogenase and a mitochondrial locus cytochrome c oxidase subunit I revealed that the mung bean isolates grouped in the same clade as P. vignae and its two formae speciales, P. vignae f. sp. adzukicola and P. vignae f. sp. vignae. A host specificity test showed that the mung bean isolates of P. vignae were pathogenic toward mung bean with a much stronger virulence and toward adzuki bean with a relatively weak virulence, but they were nonpathogenic to the other tested legume crops, including soybean, cowpea, pea, common bean, faba bean, and chickpea. The host range of mung bean isolates significantly differs from those of P. vignae f. sp. adzukicola and P. vignae f. sp. vignae based on our results and on previous studies. Thus, the pathogen causing Phytophthora stem rot of mung bean is proposed as a new forma specialis of P. vignae, designated as P. vignae f. sp. mungcola
