한국농업미생물자원센터(KACC)에 보존중인 Colletotrichum gloeosporioides와 C. acutatum의 재동정

초록

Thirty-nine strains of Colletotrichum gloeosporioides and 5 strains of C. acutatum stored in Korean Agricultural Culture Collection (KACC) were re-identified based on molecular characteristics of ribosomal internal transcribed spacer (ITS) and partial β-tubulin gene and cultural characteristics on potato dextrose agar (PDA) and Benomyl-added PDA. As the results, 19 strains were identified as C. acutatum with 13 strains of group A2, 5 strains of group A3, and 1 strain of group A4. In addition, 20 strains were identified as C. gloeosporioides with 18 strains of ribosomal DNA group (RG) 4 and 2 strains of RG6. The rest were identified as C. boninense RG5 (2 strains), C. coccodes RG2 (2 strains), and C. dematium RG12 (1 strain). Out of domestic 31 strains, 12 strains were identified as C. acutatum A2, one strain as C. acutatum A3, 14 strains as C. gloeosporioides RG4, 2 strains as C. gloeosporioides RG6, one strains as C. boninense RG5 and one strain as C. dematium RG12. We also discussed taxonomy of C. gloeosporioides and C. acutatum and composition of C. gloeosporioides/C. acutatum isolates from major crops in Korea.
