“…The use of molecular data has greatly facilitated the clarification of fungal taxonomy, including of sooty moulds, and many taxa have been revised or introduced (Hongsanan et al, 2020; Hyde et al, 2013; Li et al, 2020). At the same time, new sooty mould species are constantly being identified (Hongsanan et al, 2015; Mesquita et al, 2022; Xu et al, 2020). The currently available evidence indicates that sooty moulds are polyphyletic and include species belonging to two different classes, namely, Dothideomycetes and Eurotiomycetes (Chomnunti et al, 2014; Chomnunti, Ko, et al, 2012).…”

Sooty moulds are a widespread group of saprophytic ascomycetes that obtain nutrients from honeydew excreted by sap‐feeding insects and coat plant tissue with mycelia. Research on sooty moulds has focused on fungal morphology and phylogeny‐based taxonomy, but little research has been conducted on the community structure. In this study, the PacBio sequencing platform was used to systematically analyse the fungal and bacterial diversity of the sooty mould community on camphor trees at two sampling sites. Six dominant sooty mould genera were identified, of which three genera of Dothideomycetes were enriched only in diseased samples, while three genera of Eurotiomycetes were present in both healthy and diseased samples. Bacterial diversity and co‐occurrence network analysis indicated that the sooty moulds had an effect on the leaf surface bacterial communities but not on the endophyte communities. There was a close correlation between the six dominant pathogenic groups and bacteria in the soot layer. Transcriptomic data from Cinnamomum camphora samples showed that the sooty moulds that did not penetrate plant cells not only affected plant photosynthesis but also induced plant defence responses. This study systematically studied the microbial community of sooty moulds, indicating the close relationship between sooty moulds and the bacterial communities.

“…Disease outbreaks caused by this pathogenic fungus are usually accompanied by severe insect infestations (Chomnunti et al, 2014;Khalkho et al, 2021). In contrast, M. camelliae, as a parasitic type, typically infects the extrafloral nectaries region of plant leaves and stems, drawing nutrients from plant tissues to fuel its growth (Mesquita et al, 2022). Severe cases of C. oleifera coal stain have been documented to cause a reduction in yields by 60-70%, which can persist for years to come, ultimately leading to no harvest (Chen, 1980).…”

Camellia oleifera Abel, a woody oil plant, that is endemic to China. Tea oil, also referred to as “oriental olive oil,” is a superior quality plant-based cooking oil. The production of tea oil accounts for 8% of the total edible vegetable oil production in the country. Since 2022, the annual output value of C. oleifera industry has exceeded 100 billion yuan, making it one of the major economic contributors to China’s rural revitalization development strategy. In recent years, demand and production have grown in parallel. However, this has led to an increase in the incidence levels of pest and diseases. Pests and diseases significantly reduce the quality and yield of C. oleifera. C. oleifera diseases are mainly caused by pathogenic fungi. C. oleifera anthracnose, soft rot, leaf spot, coal stain, leaf gall disease, and root rot are the most important fungal diseases affecting the C. oleifera industry. However, the same disease may be caused by different pathogenic fungi. C. oleifera can be found in half of China and is found in several climatic zones. The geographical distribution of woody plant diseases is consistent with the distribution of the tree species and the ecology of the range, which also results in a highly complex distribution of fungal diseases of C. oleifera. The management of fungal diseases in C. oleifera is extremely challenging due to the variety of pathogenic fungal species, multiple routes of transmission, the lack of resistant plants, and the environmental safety of chemical measures. The optimal strategy for addressing fungal diseases in C. oleifera is to develop and apply an integrated disease management plan. This review provides a brief overview of the pathogenic species, pathogenesis, pathogenesis, geographical distribution, current management strategies, and potentially new methods of C. oleifera fungal diseases, to provide direction for the development of comprehensive management measures for C. oleifera fungal diseases in the future.
