“…All strains shared 100% identity with strain ICMP19812 type strain of Ciborinia camelliae from New Zealand (Massey University Arboretum, Palmerston North) used for the genome project of Ciborinia camellieae, with sequence accession number LGKQ00000000.1. The complete identity with a C. camelliae strain together with peculiar morphological characters of sclerotia formed on camelia petals and micromorphological description of reproductive structures (Kohn and Nagasawa 1984;Taylor and Long 2000;Saracchi et al 2019) confirmed species identity of the examined strains.…”

“…Ciborinia camelliae Kohn is a pathogenic fungus that affects plants of the genus Camellia. The pathogen infects only flowers causing a disease called camellia flower blight (CFB) (Taylor and Long 2000;Saracchi et al 2019). The infection occurs when the spores land on camellia flowers, where they germinate, penetrate petal tissues and cause extensive damage to flowers (Taylor 2004).…”

Ciborinia camelliae Kohn is the causal agent of Camellia flower blight. The pathogen infects only flowers of camellias, causing serious damage to the plant. Seventy-one strains were collected from six Italian regions and were characterized at the phenotypic and genetic level. Morphotypes were identified based on their phenotypic differences in culture media. The Italian population consisted of eleven morphotypes. Internal transcribed spacer (ITS) regions of twenty-two isolates belonging to the different morphotypes were sequenced. All morphotypes have identical ITS sequences. The closest match of the ITS with the strain ICMP 19812 of Ciborinia camelliae from New Zealand (Massey University Arboretum, Palmerston North, 100 % sequence identity), and the morphological features confirmed the presence of a variable population of C. camelliae in six different Italian regions.

Oil tea (Camellia oleifera), mainly used to produce high-quality edible oil, is an important cash crop in China. Anthracnose of oil tea is a considerable factor that limits the yield of tea oil. In order to effectively control the anthracnose of oil tea, researchers have worked hard for many years, and great progress has been made in the research of oil tea anthracnose. For instance, researchers isolated a variety of Colletotrichum spp. from oil tea and found that Colletotrichum fructicola was the most popular pathogen in oil tea. At the same time, a variety of control methods have been explored, such as cultivating resistant varieties, pesticides, and biological control, etc. Furthermore, the research on the molecular pathogenesis of Colletotrichum spp. has also made good progress, such as the elaboration of the transcription factors and effector functions of Colletotrichum spp. The authors summarized the research status of the harm, pathogen types, control, and pathogenic molecular mechanism of oil tea anthracnose in order to provide theoretical support and new technical means for the green prevention and control of oil tea anthracnose.

“…Mycelial plugs (5 mm) from PDA were placed in the center of PDA plates and cultured in incubators set at different temperatures (10,15,20,25,28,30, and 35 • C) for 5 days. Moreover, 5 mm mycelial plugs from PDA were placed in the center of PDA plates adjusted to a range of pH values from 3.0 to 10.0 for 5 days in an incubator at 28 • C. Na 2 HPO 4 -citric acid buffer was used to prepare PDA with pH values of 3.0-8.0, while Na 2 CO 3 -NaHCO 3 buffer was used to prepare PDA at pH values 9.0 and 10.0.…”

Camellia yuhsienensis Hu, a species of tea oil tree with resistance to anthracnose, is widely used to breed disease-resistant Camellia varieties. In 2019, anthracnose symptoms were observed on Ca. yuhsienensis for the first time. However, the species and biological characteristics of Colletotrichum spp. isolated from Ca. yuhsienensis (YX-Colletotrichum spp.) have not been elucidated. In this study, five isolates (YX2-5-2, 2YX-3-1, 2YX-5-1, 2YX-8-1-1 and 2YX-8-1-2), which were consistent with the morphological characteristics of Colletotrichum spp., were obtained from Ca. yuhsienensis. A phylogenetic analysis demonstrated that YX2-5-2, 2YX-3-1 and 2YX-8-1-2 belonged to first clade along with Colletotrichum fructicola. 2YX-8-1-1 belonged to the second clade along with Colletotrichum siamense. 2YX-5-1 belonged to the third clade with Colletotrichum camelliae. Pathogenicity tests revealed that the pathogenicity of YX-Colletotrichum spp. was stronger than that of Colletotrichum spp. isolated from Camellia oleifera (GD-Colletotrichum spp.). Biological characteristics illustrated that the mycelial growth of YX-Co. camelliae (2YX-5-1) was slower than that of GD-Co. camelliae when the temperature exceeded 20 °C. In addition, in the presence of ions, the mycelial growth of YX-Co. fructicola (YX2-5-2) and YX-Co. siamense (2YX-8-1-1) was also slower than that of GD-Co. fructicola and GD-Co. siamense. Furthermore, the ability of YX-Colletotrichum spp. to utilize lactose and mannitol was weaker than that of GD-Colletotrichum spp., while the ability to utilize NH4+ was generally stronger than that of GD-Colletotrichum spp. This is the first report of anthracnose of Ca. yuhsienensis induced by Co. fructicola, Co. siamense and Co. camelliae in China. These results will provide theoretical guidance for the study of the pathogenesis and control of anthracnose on Ca. yuhsienensis.
