Fusarium, a member of the Ascomycota fungi, encompasses several pathogenic species significant to plants and animals. Some phytopathogenic have received special attention due their negative economic impact on agricultural industry around world. Traditionally, identification taxonomic analysis Fusarium relied morphological phenotypic features, including fungal host, leading conflicts that been solved using molecular systematic technologies. In this work, we applied phylogenomic approach allowed us resolve evolutionary history complexes genus present evidence supports F. ventricosum complex as most basal lineage genus.

A survey of the fungal diversity associated with mixed pastures from Eastern Cape dairy farms in South Africa led to isolation 155 Fusarium strains that belong incarnatum-equiseti species complex (FIESC). Using single and multigene phylogenies based on partial sequences translation elongation factor 1-alpha ( TEF ), calmodulin CaM RNA polymerase second largest subunit RPB2 ) genes, we identified 11 species. They included F. brevicaudatum , clavus coffeatum croceum goeppertmayerae heslopiae five were found be new. Based morphological phylogenetic data, three new are formally described here as cumulatum mariecurieae pascuum . We also provided a description for authors who named this did not include one. have chosen describe remaining species, our cultures lack proper structure development. This study shows harbour diverse range highlights need further studies into their potential impact animal health.

Root rot is a major disease that causes decline of alfalfa production, and Fusarium pathogen associated with root rot. In this study, 13 isolates were obtained from in Gansu Province, the production region China. The characterized by molecular genotyping ( ITS , TEF 1-α RPB2 fragments) identified as six species, which included F. acuminatum incarnatum oxysporum proliferatum redolens F . solani We found their morphology varied significantly at both macro- micro-levels, even for those same species. developed low cost fast pathogenicity test revealed all pathogenic to typical symptoms such leaf yellowing brown lesions on stem. However, virulence differed. also conidia germinated early 24 hours post inoculation (hpi), while hyphae colonized extensively invaded xylem vessel 48 hpi. Together our results reveal different virulent use similar invasion strategy alfalfa. This natural plant-fungus pathosystem intriguing warrants further examination, particularly regard efforts aimed mitigating impact multiple vascular pathogens infected plants.

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

The combination of low temperatures, oligotrophic conditions, high altitude, and varying salinity in Tibetan Plateau lakes endows them with a wealth distinctive fungal resources. This study aimed to investigate the diversity culturable fungi sediment water samples collected from six located on at elevations above 4,500 m. A total 843 strains were isolated by dilution plate method using four different media. Initial ITS analyses revealed that they belong 156 species across 83 genera, spanning 50 families, 26 orders, 12 classes, 6 phyla. Further morphological multi-locus phylogenetic conducted, resulting formal descriptions new genus, Xizangia, seven species, including Alternaria xizangensis, Emericellopsis ovoidea, Myceliophthora xizangica, Preussia cylindricalis, sedimenticola, Pseudeurotium Xizangia sedimenticola. research provides insights into biodiversity unique extreme ecosystem, shedding light potential discovery novel genera.

The Fusarium species is an important plant pathogen that can cause diseases in grassland, leading to the degradation of grassland quality. However, morphology greatly affected by environmental factors, which makes it difficult identify its species. In addition, pathogenic ability different plants has not been fully studied. this study, isolates were obtained from herbaceous via tissue separation. Through morphological means and based on ITS, RPB2, TEF-1 gene sequences, we compared constructed polygenic phylogenetic trees classify pathogenicity was also analyzed. results showed a total 24 strains successfully isolated ten identified: F. flagelliforme, longifundum, clavum, scirpi, ipomoeae, oxysporum, etc. included four complexes: incarnatum-equiseti complex (FIESC), oxysporum (FOSC), tricinctum (FTSC), sambucinum (FSAMSC). Pathogenicity tests demonstrated except for ipomoeae QJ5211, QJ203, acuminatum QJ1662, other had degrees ability. This first study discusses effect disease control area. further provides clear information prevention diseases.

Fusarium crown rot (FCR) poses a major threat to wheat production in the Huanghuai region of China. This study aims enhance understanding pathogen populations causing FCR, focusing on their pathogenicity, trichothecene genotypes, and fungicide resistance. During 2022–2023 growing seasons, we collected 1820 fungal isolates from 233 locations this region. Our results identified pseudograminearum, graminearum, asiaticum as primary pathogens, with F. pseudograminearum exhibiting highest virulence. Three genotypes were identified, including nivalenol, 3-acetyldeoxynivalenol, 15-acetyldeoxynivalenol. No correlation was observed between genotype virulence, except asiaticum. Antifungal assays demonstrated that all six tested fungicides effectively inhibited fludioxonil being particularly effective. Field surveys resistant difenoconazole pyraclostrobin. Laboratory analysis also revealed strains FpSdhC1A83 V FpSdhC1S80N mutations conferring resistance cyclobutrifluram. These findings offer critical insights for developing effective control strategies manage FCR.
