Stem blight is a significant disease affecting blueberries worldwide, caused by various pathogens. This study investigated stem in Ji’an, Jilin Province, China. Fungi isolated from diseased stems were identified as Colletotrichum temperatum, Curvularia austriaca, and Diaporthe unshiuensis based on morphological characters multi-locus phylogenetic analyses using the internal transcribed spacer (ITS) region, glyceraldehyde 3-phosphate dehydrogenase (gapdh), chitin synthase (chs), actin (act), β-tubulin (tub2), translation elongation factor 1-alpha (tef1-α), calmodulin (cal), histone 3 (his3) regions. Pathogenicity test was conducted detached green blueberry shoots, all shoots inoculated mycelium plugs presented necrotic lesions with dark brown margins, while control (PDA plugs) group did not show any symptoms. Koch’s postulates confirmed re-isolating pathogen The provides three new host–pathogen records of fungi associated blight.

Fungal Diversity, Год журнала: 2023, Номер 121(1), С. 1 - 94

Abstract Hypocreomycetidae is a highly diverse group with species from various habitats. This subclass has been reported as pathogenic, endophytic, parasitic, saprobic, fungicolous, lichenicolous, algicolous, coprophilous and insect fungi aquatic terrestrial In this study, we focused on freshwater of which resulted 41 fresh collections China Thailand. Based morphological phylogenetic analyses, identified 26 that belong to two orders ( Hypocreales Microascales ) six families Bionectriaceae , Halosphaeriaceae Microascaceae Nectriaceae Sarocladiaceae Stachybotryaceae ). Ten new are introduced 13 habitats geographic records reported. Mariannaea superimposita, Stachybotrys chartarum S. chlorohalonatus recollected in China. analysis combined LSU, ITS, SSU, rpb 2 tef 1-α sequences data, Emericellopsis transferred genera incertae sedis ; Pseudoacremonium Sedecimiella placed Nautosphaeria Tubakiella excluded Faurelina . Varicosporella under Atractium synonym addition, divergence time estimates showed Ascocodina Campylospora Cornuvesica Xenodactylariaceae form distinct lineages they evolved the family/order frame. Hence, order Xenodactylariales three Ascocodinaceae Campylosporaceae Cornuvesicaceae based analysis, estimations characters. Ancestral character state performed for different including freshwater, marine taxa. The result indicates independently ancestors. results further support those early diverging clades subclass, mostly comprising taxa have secondarily derived, while crown clade represented all evolution adaptations towards their habitual changes also discussed.
