The order Sordariales is taxonomically diverse, and harbours many species with different lifestyles large economic importance. Despite its importance, a robust genome-scale phylogeny, associated comparative genomic analysis of the lacking. In this study, we examined whole-genome data from 99 Sordariales, including 52 newly sequenced genomes, seven outgroup taxa. We inferred comprehensive phylogeny that resolved several contentious relationships amongst families in order, cleared-up...
Abstract Thermophily is a trait scattered across the fungal tree of life, with its highest prevalence within three families (Chaetomiaceae, Thermoascaceae, and Trichocomaceae), as well some members phylum Mucoromycota. We examined 37 thermophilic thermotolerant species 42 mesophilic for this study identified thermophily ancestral state all prominent fungi. Thermophilic genomes were found to encode various thermostable enzymes, including carbohydrate-active enzymes such endoxylanases, which...
We report a comprehensive multi-year study of thermophilic fungi at the Sevilleta National Wildlife Refuge in central New Mexico. Recovery from soils showed seasonal fluctuations, with greater abundance correlating spring and summer precipitation peaks. In addition to grassland soils, we obtained characterized isolates riparian litter, herbivore dung biological soil crusts. All strains belonged either Eurotiales or Sordariales (Chaetomiaceae). No particular substrate microhabitat...

Darksidea is a common genus of dark septate fungi-a group ascomycetes in semiarid regions. A survey reported D. alpha and distinct lineage as abundant root-associated fungi foundational grasses North America. Fungi were isolated, metabarcode data obtained from sequencing fungal communities grass roots the United States. During comprehensive investigation lineage, we carried out polyphasic taxonomy, genomic characterization, identification host associations, geographic distribution,...
Corn bins in the midwestern United States can reach temperatures up to 52 C. High combined with sufficient moisture and humidity provide perfect environment promote growth of thermophilic thermotolerant fungi. In this article, we characterize for first time fungi corn grain using culture-based methods pyrosequencing techniques. samples were collected from local farms western Illinois. Samples plated incubated at 50 C a variety approaches. Of several hundred kernels examined, more than 90%...
Genes associated with elevated oxidative enzyme activities in arid systems have not been well characterized. To link measured specific enzymes, we assembled protein-coding reads from the rhizospheres (RHZ) of two land grasses. Targeted gene scans for open reading frames, encoding genes potentially involved lignin modification, resulted 127 distinct assembly products. The putative included those significantly similar to Class II secretory fungal peroxidases. These are expressed at...
Diverse fungi colonize plant roots worldwide and include species from many orders of the phylum Ascomycota. These taxa with dark septate hyphae that grass may modulate responses to stress. We describe a novel group fungal isolates evaluate their effects on Bouteloua gracilis in vitro. isolated six native grasses 24 sites spanning replicated latitudinal gradients south-central US grasslands characterized phylogenetically using genome analysis. analyzed 14 representing clade within family...
Abstract We conducted a preliminary survey of the fungal communities associated with roots Stipa hymenoides and Hilaria jamesii, two grasses native to southwestern United States. Root samples from 10 different plants were collected at semiarid grassland in Utah. Fungal assessed using microscopic molecular methods. Roots cleared KOH stained blue ink visualize mycorrhizal endophytic fungi. A total 100 root segments surface sterilized plated on malt extract agar antibiotics. endophytes...
