For nearly 450 million years, mycorrhizal fungi have constructed networks to collect and trade nutrient resources with plant roots1,2. Owing their dependence on host-derived carbon, these face conflicting trade-offs in building that balance construction costs against geographical coverage long-distance resource transport from roots3. How they navigate design challenges is unclear4. Here, monitor the of living networks, we built a custom-designed robot for high-throughput time-lapse imaging...
There is a global industry built upon the production of “bioinoculants,” which include both bacteria and fungi. The recent increase in bioinoculant uptake by land users coincides with drive for more sustainable use practices. But are bioinoculants sustainable? These microbes believed to improve plant performance, but knowledge their effect on resident microbial communities scant. Without clear understanding how they affect soil (SMC), utility unclear. To assess different inoculation...
Droplet digital polymerase chain reaction (ddPCR) is a method used to detect and quantify nucleic acids even when present in exceptionally low numbers. While it has proven be valuable for clinical studies, failed widely adopted environmental studies but despite some limitations, ddPCR may represent better option than classical qPCR samples. Due the complexity of chemical biological composition samples, protocols tailored are not appropriate, results difficult interpret. We DNA samples...
The arbuscular mycorrhizal fungi (AMFs) are obligate root symbionts in the subphylum Glomeromycotina that can benefit land plants by increasing their soil nutrient uptake exchange for photosynthetically fixed carbon sources. To date, annotated genome data from representatives of AMF orders Glomerales, Diversisporales and Archaeosporales have shown these organisms large highly repeated genomes, no genes to produce sugars fatty acids. This led hypothesis most recent common ancestor (MRCA) was...
Summary Rhizophagus irregularis is the model species for arbuscular mycorrhizal fungi (AMF) research and most widely propagated commercial plant biostimulants. Using asymbiotic symbiotic cultivation systems initiated from single spores, advanced microscopy, Sanger sequencing of glomalin gene, PacBio partial 45S rRNA we show that four strains R. produce spores two distinct morphotypes, one corresponding to morphotype described in protologue other having phenotype R . fasciculatus The spore...
Transformed root cultures (TRC) are used to mass produce Arbuscular Mycorrhizal (AM) fungal propagules in vitro. These then research, agriculture and ecological restoration. There many examples from other microbial systems that long term vitro propagation leads domesticated strains differ genetically functionally. Here we discuss potential consequences of TRC on AM traits, how this may affect their functionality. We examine weather domestication fungi has already happened finally, explore...

<title>Abstract</title> Arbuscular mycorrhizal (AM) fungal strains of <italic>Rhizophagus irregularis</italic> can occur in two genetic groups: homokarya, which nuclei are genetically similar and dikarya, they harbor different nuclear populations. Data show trait conservatism these groups, but their adaptability to environmental changes remains unclear. We tested if dikaryotic potentially adapt faster soil phosphorus (P) conditions than homokaryotic strains. First, the growth responses...
Abstract Transposable elements are repetitive DNA sequences that excise or create copies inserted elsewhere in the genome. Their expansion shapes genome variability and evolution by impacting gene expression rearrangement rates. Arbuscular mycorrhizal fungi beneficial plant symbionts with large, transposable element-rich genomes, recent findings showed these vary significantly abundance, evolution, regulation among model strains. Here, we aimed to obtain a more comprehensive understanding of...
Arbuscular mycorrhizal fungi (AMF) are obligate plant symbionts that have the potential to improve crop yield. These multinucleate organisms either “homokaryotic” or “dikaryotic”. In AMF dikaryons, thousands of nuclei originating from two parental strains coexist in same cytoplasm. other fungi, homokaryotic and dikaryotic show distinct life history traits (LHTs), such as variation growth rates fitness. However, how compare between dikaryons homokaryons is unknown. To address this, we...
Abstract Differences in functioning among various genotypes of arbuscular mycorrhizal (AM) fungi can determine their fitness under specific environmental conditions, although knowledge the underlying mechanisms still is very fragmented. Here we compared seven homokaryotic isolates (genotypes) Rhizophagus irregularis , aiming to characterize range intraspecific variability with respect hyphal exploration organic nitrogen (N) resources, and N supply plants. To this end established two...
Arbuscular mycorrhizal (AM) fungi associate with most plants and can increase nutrient uptake. As a result, commercial inoculants called "biofertilizers" containing AM have been developed marketed to plant performance. However, successful establishment of these remains challenge, may be negatively impacted by competition already present (priority effects). Perennial agriculture more amenable if successfully established on crops prior field planting.Here, we inoculate grapevine (Vitis...
We proposed a theoretical framework predicting mutualistic outcomes for the arbuscular mycorrhizal (AM) symbiosis based on host provenance (crop versus wild). To test framework, we grew two isolates of Rhizoglomus irregulare (commercial an isolate locally isolated), with five crop plants and wild endemic to region that co-occur sourced fungus. While inoculation either had no effect plant biomass, it decreased leaf P content, particularly plants. All associating commercial fungus lower P....
