초록

영어
Gastrodia elata is a saprophytic perennial plant in achlorophyllous orchidaceae, which has a myco-heterotrophic lifestyle with decrease leaves and bracts in scape. In the life cycle, G. elata is related to two types of fungi: Mycena spp. for seed germination to form vegetative propagation and Armillaria mellea for vegetative growth to develop tubers. Several fungal pathogens have caused root rot of Gastrodia elata in Korea. There is a need for research of pathogens with G. elata, anticipating the severity of the reduction. In this study, we identified necrotic spots on tubers of G. elata from commercial fields in Anseong and obtained infected tissues. The disease symptoms showed round and grayish-brown spots, which eventually merged into larger black lesions on tubers. All colonies from symptomatic tissues were yellowish-white and the surface was covered with thick aerial hyphae. We were confirmed by sequencing three fungal loci (internal transcribed spacer regions 1 and 4, translation elongation factor alpha, and beta-tubulin). The fungus was identified C. chlorolueca by multigene phylogenetic analysis and morphological observation. It is the first report of C. chlorolueca causing root rot on G. elata in Korea. Our result may assist to make the proper measures to control this disease in the commercial fields of G. elata in Korea.
