| Abstract: | From 2019 to 2021, the sample leaves with typical anthracnose disease symptoms were collected from tree peony (Paeonia suffruticosa Andr.) in Anhui of China. Thirty-one fungal isolates obtained from the diseased samples and the purified cultures exhibited the same morphological characteristics on potato sucrose agar. Pathogenicity tests for the representative AF614 revealed that that this fungus was the causal agent of the disease. Molecular analysis of the sequences for the internal transcribed spacer (ITS) regions of their rDNA and the partial DNA fragments of actin (ACT), β-tublin (TUB2), and chitin synthase (CHS) genes showed the orthologues with these of Colletotrichum siamense species. Combined with morphological and molecular characteristics, we named the fungal AF614 as Colletotrichum siamense. To the best of our knowledge, this is the first report of C. siamense causing anthracnose of tree peony in China. |
