Two Endophytic Diaporthe Species Isolated from the Leaves of Astragalus membranaceus in Korea.

We characterized two endophyte fungi from the leaves of Astragalus membranaceus in Korea. The isolated strains were identified on the basis of the morphological characters and sequences analysis of the internal transcribed spacer and large subunit regions of the rDNA and ß-tubulin gene. To the best of our knowledge, this is the first report of Diaporthe oncostoma and Diaporthe infecunda in Korea, and we have provided descriptions and figures.
