Abstract

Solidago virgaurea subsp. gigantea is native to Ulleung-do, island in East Sea, and cultivated as a vegetable in Korea. Rust fungus on this plant was first reported as Coleosporium asterum in 2014. Recent studies on Solidago-Coleosporium association mainly based on North American materials suggested that the Korean isolates of C. asterum on S. virgaurea subsp. gigantea reported in Korea might be placed in the C. solidaginis clade. Accordingly, to confirm this suggestion, three additional Korean samples were morphologically and molecularly studied and identified as C. solidaginis in current species concept. Three specimens on S. altissima (syn. S. canadensis) from China and Japan were previously determined to be phylogenetically differentiated from C. solidaginis, hinting at a cryptic species. Therefore, this is the first confirmed report on the presence of C. solidaginis on Solidago spp. in Asia.

울릉미역취는 울릉도 원산이지만 한국에서 채소로 널리 재배된다. 울릉미역취의 녹병균은 2014년에 Coleosporium asterum으로 처음 보고되었다. 최근에 북미 시료를 중심으로 미역취속(Solidago)의 녹병균(Coleosporium)을 연구한 논문을 통하여 앞서 한국에서 보고된 울릉미역취 녹병균은 C. solidaginis에 포함시켜야 한다는 의견이 있었다. 이 의견을 확인하기 위하여 고려대학교 표본실에 보존된 울릉미역취 녹병균 시료 3점을 연구하여 C. solidaginis임을 확인하였다. 일본과 중국에서 보고된 양미역취의 녹병균은 C. asterum이나 C. solidaginis과는 구분되는 잠재종으로 추정된다. 본 연구를 통하여 그 동안 북미와 유럽에서만 알려졌던 C. solidaginis가 아시아에도 존재한다는 사실을 처음으로 보고한다.
