“…This is especially important when it comes to publishing peer-reviewed disease reports, where imprecise and/or incorrect identifications erode public knowledge. The translation elongation factor-1α ( TEF1) [ 40 ] and RPB2 genes [ 87 ] used in this study are the most commonly used genes in the phylogenetic analyses of Fusarium species, with TEF1 serving as a de facto barcode for the genus, though numerous other genes have also been used [ 86 , 88 , 89 , 90 , 91 ]. Using sequencing analysis of each locus and phylogenetic analysis of two genomic loci, all Fusarium isolates in the present investigation were correctly identified.…”

Fungal species associated with crown and root rot diseases in wheat have been extensively studied in many parts of the world. However, no reports on the relative importance and distribution of pathogens associated with wheat crown and root rot in Kyrgyzstan have been published. Hence, fungal species associated with wheat crown/root rot were surveyed in three main wheat production regions in northern Kyrgyzstan. Fungal species were isolated on 1/5 strength potato-dextrose agar amended with streptomycin (0.1 g/L) and chloramphenicol (0.05 g/L). A total of 598 fungal isolates from symptomatic tissues were identified using morphological features of the cultures and conidia, as well as sequence analysis of the nuclear ribosomal internal transcribed spacer (ITS) region, the translation elongation factor 1α (TEF1), and the RNA polymerase II beta subunit (RPB2) genes. The percentage of fields from which each fungus was isolated and their relative percentage isolation levels were determined. Bipolaris sorokiniana, the causal agent of common root rot, was the most prevalent pathogenic species isolated, being isolated from 86.67% of the fields surveyed at a frequency of isolation of 40.64%. Fusarium spp. accounted for 53.01% of all isolates and consisted of 12 different species. The most common Fusarium species identified was Fusarium acuminatum, which was isolated from 70% of the sites surveyed with an isolation frequency of 21.57%, followed by Fusarium culmorum, Fusarium nygamai, Fusarium oxysporum, and Fusarium equiseti, all of which had a field incidence of more than 23%. Inoculation tests with 44 isolates representing 17 species on the susceptible Triticum aestivum cv. Seri 82 revealed that Fusarium pseudograminearum and F. culmorum isolates were equally the most virulent pathogens. The widespread distribution of moderately virulent B. sorokiniana appears to be a serious threat to wheat culture, limiting yield and quality. With the exception of F. culmorum, the remaining Fusarium species did not pose a significant threat to wheat production in the surveyed areas because common species, such as F. acuminatum, F. nygamai, F. oxysporum, and F. equiseti, were non-pathogenic but infrequent species, such as Fusarium redolens, Fusarium algeriense, and F. pseudograminearum, were highly or moderately virulent. Curvularia inaequalis, which was found in three different fields, was mildly virulent. The remaining Fusarium species, Fusarium solani, Fusarium proliferatum, Fusarium burgessii, and Fusarium tricinctum, as well as Microdochium bolleyi, Microdochium nivale, and Macrophomina phaseolina, were non-pathogenic and considered to be secondary colonizers. The implications of these findings are discussed.

“…Among the described new species, nearly 200 are classi ed in three subphyla of Basidiomycota, namely Agaricomycotina, Pucciniomycotina and Ustilaginomycotina (Boekhout et al 2022, Li et al 2020. Our recent description of more than 120 yeast species covering the 20 years of yeast collection in our group (Li et al 2020(Li et al , 2022 increased the species diversity of basidiomycetous yeasts by 20% (Boekhout et al 2022). However, the described species from China or worldwide presents only the tip of the iceberg of yeast species diversity in nature.…”

“…The rapid growth of new species number in the last 20 years was mainly due to the progressive taxonomic survey in Asia (Boekhout et al 2022). The yeast diversity from various substrates in China has been investigated over the past decades, and nearly 800 yeast species including more than 280 new species have been reported (Boekhout et al 2022, Li et al 2022). Among the described new species, nearly 200 are classi ed in three subphyla of Basidiomycota, namely Agaricomycotina, Pucciniomycotina and Ustilaginomycotina (Boekhout et al 2022, Li et al 2020.…”

More than 2,000 yeast strains isolated from 1200 samples mostly collected from Tibet and Yunnan provinces were identified as 466 species according to the internal transcribed spacer including the 5.8S rDNA (ITS) and the D1/D2 domains of the large subunit rDNA (LSU) sequence analyses. Among them, 78 new basidiomycetous yeast species were proposed based on the multi-locus phylogenetic analyses including the D1/D2 domains, the ITS, the small subunit rDNA (SSU), the largest subunit of RNA polymerase II (RPB1), the second largest subunit of RNA polymerase II (RPB2) and translation elongation factor 1-α (TEF1), as well as the phenotypic comparisons. Fifty-three new species belong to 17 genera in the Agaricomycotina, 19 new species occur in 12 genera in the Pucciniomycotina and six new species distribute in four genera in the Ustilaginomycotina, and eleven new species were classified in nine newly established genera. Two new families and one new order were also proposed based on two of these new genera. The genus Guomyces and the species Guomyces nicotianae were validated.
