Recombination in the Asexual Fungus Glomus intraradices

Author(s): Croll Daniel, Sanders Ian R
Primary Institution: University of Lausanne
Hypothesis
Does Glomus intraradices exhibit recombination despite being considered an ancient asexual fungus?
Conclusion
The study found that Glomus intraradices has undergone recombination while also maintaining clonal lineages.
Supporting Evidence
- Phylogenetic analysis showed a reticulate network pattern among genotypes.
- Five statistical tests indicated multiple recombinant regions in the genome.
- Evidence of recombination was found among five isolates supported by multiple tests.
Takeaway
Scientists studied a type of fungus and found that it can mix its genes, even though it was thought to only reproduce without mixing.
Methodology
Sequencing of 11 polymorphic nuclear loci in 40 isolates from one field to test for recombination.
Potential Biases
Potential biases from using in vitro cultures instead of field-collected samples.
Limitations
The study may not capture all genetic diversity due to the limited number of isolates and loci analyzed.
Participant Demographics
40 morphologically identical isolates from one field in Tänikon, Switzerland.
