Tea ( (L.) Kuntze) is one of the most important economic plants in China, and has many benefits for human health. Anthracnose is one of the most serious diseases of tea in China, and control of the fungus is important since most Chinese cultivars are susceptible to it. The agent of tea anthracnose was initially described as I. Miyake in Japan, which was later transferred to , but this taxonomic position remains problematic. To shed light on these taxonomic and phylogenetic issues, the tea anthracnose pathogens were re-studied. Combining the morphological characteristics and a multigene phylogenetic analysis of nrITS, nrLSU, , and sequence data, a new genus was proposed to accommodate the causal fungi of tea anthracnose, including a new species and a new combination . Furthermore, the pathogenicity of the pathogens was determined according to Koch's postulates. This study thoroughly resolves the long-standing taxonomic and phylogenetic problems of the tea anthracnose pathogens.

Anthocyanins, key quality components of tea, act as an important bridge between plants and the environment due to their function on protecting plants from biotic and abiotic irritants. This study aimed to assess the interactions between anthocyanins metabolism and the environment. Purple (P) and green (G) leaves with different anthocyanin contents were inoculated with tea plant anthracnose.

Anthracnose of the tea plant (), caused by spp., poses a significant threat to both the yield and quality of tea production. To address this challenge, researchers have looked to the application of endophytic bacteria as a natural alternative to the use chemical pesticides, offering potential for enhancing disease resistance and abiotic stress tolerance in tea plants.

Article Synopsis
- Polygonatum odoratum var. pluriflorum, or Lesser Solomon's seal, is a perennial plant found in temperate regions, valued for its medicinal properties, including tea production.
- In September 2021, a new type of anthracnose, caused by the fungus Colletotrichum, was reported affecting 20-30% of these plants in Chuncheon and Wanju, Korea, showing symptoms like leaf yellowing and brown lesions.
- The disease progressed during the rainy season, leading to significant leaf blight, and five fungal isolates were collected for study, with details about their morphological characteristics noted for further research.
