title: Taxonomic Re-evaluation of Colletotrichum gloeosporioides Isolated from Strawberry in Korea.
abstract: For the past two decades, the causal agent of anthracnose occurring on strawberry in Korea was considered Colletotrichum gloeosporioides. However, the recent molecular analysis has shown that the genus Colletotrichum has undergone many taxonomic changes with introduction of several new species. As a result, it revealed that C. gloeosporioides indeed consisted of more than 20 distinct species. Therefore, the Korean pathogen isolated from strawberry should be reclassified. The shape and size of the conidia of the pathogen were not distinctly different from those of C. gloeosporioides and C. fructicola, but it differed in shape of the appressoria. A combined sequence analysis of partial actin, glycer-aldehydes-3-phosphate dehydrogenase genes, and the internal transcribed spacer regions showed that the strawberry isolates formed a monophyletic group with authentic strains of C. fructicola. On the basis of these results, the anthracnose fungi of the domestic strawberry in Korea were identified as C. fructicola and distinguished from C. gloeosporioides.
