Abstract

Mortierellaceae are ecologically and economically important fungi implicated in soil health. However, the diversity and frequency of Mortierellaceae and their endobacteria in crop root systems is unclear. Roots of winter wheat were sampled using a randomized complete block design. Mortierellaceae were isolated, identified using ITS-LSU phylogenetic analysis, and 16S rDNA was screened for Burkholderia-related endobacteria (BRE) and Mollicutes-related endobacteria (MRE). A total of 102 root-associated Mortierellaceae were isolated from 217 wheat root samples. Linnemannia comprised 89% of isolates. BRE were detected in 12 isolates, while MRE were detected in only one isolate. Mortierellaceae frequency varied by cultivar and a weak trend towards cultivar specificity was observed. Together, these findings advance our understanding of BRE and MRE prevalence in fungi in agricultural soils. Further studies will be needed to determine how plant hosts recruit Mortierellaceae partners and factors that drive plant-Mortierellaceae interactions.

期刊介绍: Fungal Ecology publishes investigations into all aspects of fungal ecology, including the following (not exclusive): population dynamics; adaptation; evolution; role in ecosystem functioning, nutrient cycling, decomposition, carbon allocation; ecophysiology; intra- and inter-specific mycelial interactions, fungus-plant (pathogens, mycorrhizas, lichens, endophytes), fungus-invertebrate and fungus-microbe interaction; genomics and (evolutionary) genetics; conservation and biodiversity; remote sensing; bioremediation and biodegradation; quantitative and computational aspects - modelling, indicators, complexity, informatics. The usual prerequisites for publication will be originality, clarity, and significance as relevant to a better understanding of the ecology of fungi.
