Abstract/Contents:"Arbuscular mycorrhizal (AM) fungi are important beneficial symbiotes there is conflicting evidence for the selectivity between host-plant and fungal taxa. We examined Bermudagrass in a greenhouse to determine the effects of plant genotype and evolutionary history (Asian or African) on AM fungal root communities. Twelve cultivars of bermudagrass were vegetatively propagated for 26 weeks and grown within the same native prairie soil. Various plant physiological characteristics were quantified. We identified AM fungal taxa within the roots of each grass using 18S amplicons sequenced on a MiSeq. There were significant differences in plant physiological characteristics between genotypes and evolutionary origin. Notably, 9 of 12 genotypes (75%) had significantly more similar AM fungal communities to themselves than comparison between different genotypes. We found many indicator taxa for multiple genotypes and evolutionary origin. Our study provides evidence that plant genotypes can select for significantly different root microbiomes from a common pool of bulk soil AM fungal taxa. Further, differences in AM fungal communities between evolutionary history of the Bermudagrass indicate that these plants have evolved preferences for certain AM fungal taxa, or that the physiological characteristics of each origin create different incentives for AM fungal taxa."
