Although research has shown that root associated fungi (RAF) are necessary for plant success in harsh environments, few studies have examined RAF community variability between different plant species coexisting in arid habitats. We compared the diversity and composition of the fungal communities colonizing dominant and important forage grasses, Bouteloua gracilis and Sporobolus cryptandrus, inhabiting the Sevilleta National Wildlife Refuge, a semiarid grassland in New Mexico. A third sympatric plant, Yucca glauca (Agavaceae), also was analyzed. ITS rDNA from roots, collected and amplified in 2007, yielded 447 fungal sequences. Sequences obtained from all three species suggest that grasses share a core group of RAF...
