“…In particular, the numerically dominant Allophoma strains obtained in this study had the same ITS genes as the leaf endophyte and leaf spot pathogen Allophoma associated with A. adenophora (Chen et al, 2022; Kai Fang et al, 2021; Yang et al, 2023). Recently, these strains were identified as the novel species Mesophoma speciosa (Chen et al, 2022; Yang et al, 2023). We did not isolate fungi from healthy seedlings in this study.…”

Microbes strongly affect invasive plant growth. Interactions between soil microbes and invasive plants have received widespread attention; however, it remains to be determined how phyllosphere and rhizosphere soil microbes affect seedling mortality and the growth of invasive plants across ontogeny under varying soil nutrition levels. In this study, we used the invaderAgeratina adenophorato evaluate these effects in plant growth chambers. We found that leaf litter harboured more potential pathogens and thus had more adverse effects on seed germination and seedling survival than soil inoculation. Microbial inoculation at different growth stages altered the microbial community and functions enriched in seedlings, and earlier inoculation had a more adverse effect on seedling survival and growth. In most cases, the soil nutrient level did not affect microbe-mediated seedling growth and the relative abundance of the microbial community and functions involved in seedling growth. Some microbial genera have distinct effects on seedling survival from those on growth. Moreover, fungal strains isolated from dead seedlings inoculated with litter exhibited significant phylogenetic signals to seedling mortality, in which strains ofAllophomaandAlternariacaused high seedling mortality. Our study stresses the essential role ofA. adenophoralitter microbes in population establishment by regulating seedling density and growth.

“…Yunnan Province, as the oldest tea region in China, is rich in tea plant resources and is also the centre of fungi biodiversity. Molecular evidence suggested that many fungi belonging to the family Didymellaceae may be seedborne and can co-spread with the host through seeds ( Fang et al 2021 ; Yang et al 2023a ). Therefore, we speculated that Yunnan as the birthplace of tea plants has more abundant germplasm resources and is prone to fungal transmission.…”

“…In addition, 40 new species were identified combining phylogenetic analyses, based on concatenated DNA sequence dataset (ITS, LSU, RPB2 and TUB2 ) and morphological examination ( Hou et al 2020b ). Given the above, phylogenetic analyses, based on a combined ITS-LSU- RPB2 - TUB2 DNA sequence dataset, have been demonstrated as an effective method for the identification of Didymellaceae at species level ( Hou et al 2020a ; Yuan et al 2021 ; Kularathnage et al 2023 ; Yang et al 2023a ).…”

Tea plant is one of the most important commercial crops worldwide. The Didymellaceae fungi can cause leaf blight disease of tea plant. In this study, 240 isolates were isolated from tea plant leaves of 10 provinces in China. Combined with multi-locus (ITS, LSU, RPB2 and TUB2) phylogenetic analysis and morphological characteristics, these isolates were identified as 25 species of six genera in Didymellaceae, including 19 known species Didymella coffeae-arabicae, D. pomorum, D. segeticola, D. sinensis, Epicoccum catenisporum, E. dendrobii, E. draconis, E. italicum, E. latusicollum, E. mackenziei, E. oryzae, E. poaceicola, E. rosae, E. sorghinum, E. tobaicum, Neoascochyta mortariensis, Paraboeremia litseae, Remotididymella anemophila and Stagonosporopsis caricae, of which 15 species were new record species and six novel species, named D. yunnanensis, E. anhuiense, E. jingdongense, E. puerense, N. yunnanensis and N. zhejiangensis. Amongst all isolates, D. segeticola was the most dominant species. Pathogenicity tests on tea plant leaves showed that E. anhuiense had the strongest virulence, while E. puerense had the weakest virulence. Besides, D. pomorum, D. yunnanensis, E. dendrobii, E. italicum, E. jingdongense, E. mackenziei, E. oryzae, E. rosae, E. tobaicum, N. mortariensis, N. yunnanensis, N. zhejiangensis and R. anemophila were non-pathogenic to the tea plant.
