Tea ( [L.] O. Kuntze) is under investigation as a specialty crop in the United States. Anthracnose is a serious disease in global tea production, but there is no literature on the susceptibility of U.S. planting materials to this disease. We isolated a species from symptomatic plants in a field trial and identified the pathogen as based on morphology and sequencing of the ITS, GS, GAPDH, TUB2, and ApMat domains. A phylogenetic analysis showed that local field isolates were genetically similar to one another and grouped with isolates from in China, whereas a local isolate from an ornamental camellia () was more closely related to isolated from other spp. Six commercially available tea accessions were evaluated in detached leaf assays for susceptibility to this anthracnose pathogen. All accessions were susceptible to infection, with Fairhope and Small Leaf having the largest lesion sizes. In field observations, Fairhope, Big Leaf, and Small Leaf consistently had lower disease severity than Georgian over two growing seasons. This work documents the impact of anthracnose on U.S. tea varieties and may help shape future directions of tea research, breeding, and recommendations for growers in establishing a novel industry.

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.

is an important woody oil crop in China, and its seed oil has a high economic value. Anthracnose, one of the main diseases in , occurs in a wide range in the production areas, limiting the growth and development of plants and causing serious losses of oil production. With the rapid development of the industry in recent years, great progress has been achieved in the research on anthracnose in .

Chili anthracnose, a fungal disease caused by Colletotrichum scovillei, is among the most devastating diseases affecting pepper (Capsicum annuum L.). Although WRKY transcription factors play important roles in plant immunity, it is unknown how WRKY gene family members contribute to pepper plant resistance to C.

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.
