| Abstract: | Sequences of the internal transcribed spacer (ITS) region 1 were used to examine the phylogenetic relationships among races
of 19 isolates of Phytophthora vignae f. sp. adzukicola and between this forma specialis and three isolates of the closely related P. vignae f. sp. vignae. The ITS 1 sequences were highly conserved (> 98.7% similarity) among representatives of both formae speciales groups. The
results of this study indicate that P. vignae is a monophyletic group.
The nucleotide sequence data reported are available in the DDBJ/EMBL/GenBank databases under the accession nos. AB120062–AB120080
and AB120122 |
