Camellia yuhsienensis Hu is an endemic species from China, where is the predominant oilseed crop due to its anthracnose resistance (Kuang 2015; J. Li et al. 2020; Nie et al. 2020). In April 2019, anthracnose symptoms were observed on C. yuhsienensis in a plantation in Youxian, Zhuzhou, Hunan Province, China (113.32°E, 26.79°N). It was detected approximately 10% anthracnose incidence in 500 two-year-old plants in a 5000 m2 cultivated area. Diseased leaves showed irregular grayish brown spots with dark brown edges and dark brown undersides. Symptomatic tissues (4 to 5 mm2) were surface-disinfected for 90 s in 75% ethanol, then rinsed twice with sterile water, and finally incubated on PDA (potato dextrose agar) at 28℃ (Jiang et al. 2018). Pure cultures were obtained by the single-spore isolation method. A total of 100 fungal isolates were obtained from 85 symptomatic leaves, from which 81 had similar colony morphology. Colonies on PDA were white, fluffy and cottony, and becoming dark gray after 5 days. The character of the reverse of the colony were similar to that of the upper of the colony, but the color was darker at the same time. The isolates produced a large number of single-celled, hyaline, straight and cylindrical conidia, with 10.35 to 17.58 length × 3.46 to 5.69 μm width (x=13.61 × 4.63 μm, n = 30). The isolates were preliminarily identified as Colletotrichum spp. according to morphological features (Weir et al. 2012). Representative isolate YX2-5-2 was used for molecular identification: internal transcribed spacer (ITS), partial actin (ACT), chitin synthase (CHS-1) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) genomic DNA regions were amplified by PCR (Weir et al. 2012). Gene sequences were deposited in GenBank (GenBank accession no. MW398863 for ACT, MW886232 for CHS-1, MW398864 for GAPDH, MW398865 for ITS). BLAST analysis revealed that DNA sequences of YX2-5-2 at the ITS, GAPDH, ACT, and CHS-1 loci showed 100%, 99.25%, 100%, and 99.33% sequence identity, respectively to their corresponding loci in strains ZH6 (GenBank accession no. MT476840.1), ICKP18B4 (LC494274.1), YN17 (MN525804.1), and ICKG4 (LC469131.1) of C. fructicola. A Maximum Likelihood phylogenetic tree based on the combined ACT, CHS-1, ITS and GAPDH sequences revealed that the representative isolate YX2-5-2 clustered with C. fructicola. In addition, the morphological features of YX2-5-2 were similar to C. fructicola which has been reported (Weir et al. 2012). Pathogenicity was tested using isolate YX2-5-2 by inoculating leaves of 2-year-old C. yuhsienensis. Four leaves of each healthy C. yuhsienensis were sprayed with a conidial suspension (105 conidial/mL) of isolate YX2-5-2, and the above steps were repeated three times. Two additional mock-inoculated control plants were sprayed with sterilized liquid potato dextrose medium. The plants were incubated in a greenhouse at 28℃ and 90% humidity with a 12 h photoperiod. Anthracnose-like symptoms were observed 5 days post-inoculation. The control plant tissues remained healthy. C. fructicola was re-isolated on PDA from lesions, and the morphological features were consistent with YX2-5-2, confirming Koch's postulates. To our knowledge, this is the first report of anthracnose of C. yuhsienensis caused by C. fructicola in China. Anthracnose of Camellia. oleifera has been reported for a long time (H. Li et al. 2016). C. yuhsienensis, as a wild relative of C. oleifera (commonly known as tea-oil tree), has been concerned about its resistance to anthracnose. Therefore, the occurrence of C. yuhsienensis anthracnose hindered the control of anthracnose tea-oil tree. This finding will lay the foundation for studying the pathogenesis of anthracnose of tea-oil tree and developing effective prevention methods.
