Metabolic Potential, Ecology and Presence of Associated Bacteria Is Reflected in Genomic Diversity of Mucoromycotina

Mucoromycotina are often considered mainly in pathogenic context but their biology remains understudied. We describe the genomes of six fungi representing distant saprotrophic lineages within subphylum (i.e., Umbelopsidales and Mucorales). selected two Umbelopsis isolates from soil U. isabellina, vinacea ), soil-derived Mucor M. circinatus, plumbeus Mucorales representatives with extended proteolytic activity Thamnidium elegans saturninus) . complement computational genome annotation experimental characteristics digestive capabilities, cell wall carbohydrate composition, extensive total lipid profiles. These traits inferred e.g., terms identified encoded enzymes, accordance results. Finally, we link presence associated bacteria observed characteristics. harbors an additional, complete bacterium classified to Paenibacillus sp. This fungus displays multiple altered compared remaining isolates, regardless evolutionary distance. For instance, it has expanded carbon assimilation efficiently degrades carboxylic acids, a higher diacylglycerol:triacylglycerol ratio skewed phospholipid composition which suggests more rigid cellular membrane. The can host enzymatic alter fungal metabolism, membrane does not change fungus. Comparison early-diverging younger points at several subtle differences particularly source preferences repertoire. Nevertheless, all tested share features including ability produce 18:3 gamma-linoleic acid, use TAG as storage have fucose component.
