<jats:title>Summary</jats:title><jats:p> <jats:list list-type="bullet"> <jats:list-item><jats:p>Desert plants are hypothesized to survive the environmental stress inherent to these regions in part thanks to symbioses with microorganisms, and yet these microbial species, the communities they form, and the forces that influence them are poorly understood.</jats:p></jats:list-item> <jats:list-item><jats:p>Here we report the first comprehensive investigation of the microbial communities associated with species of <jats:italic>Agave</jats:italic>, which are native to semiarid and arid regions of Central and North America and are emerging as biofuel feedstocks. We examined prokaryotic and fungal communities in the rhizosphere, phyllosphere, leaf and root endosphere, as well as proximal and distal soil samples from cultivated and native agaves, through Illumina amplicon sequencing.</jats:p></jats:list-item> <jats:list-item><jats:p>Phylogenetic profiling revealed that the composition of prokaryotic communities was primarily determined by the plant compartment, whereas the composition of fungal communities was mainly influenced by the biogeography of the host species. Cultivated <jats:italic>A. tequilana</jats:italic> exhibited lower levels of prokaryotic diversity compared with native agaves, although no differences in microbial diversity were found in the endosphere.</jats:p></jats:list-item> <jats:list-item><jats:p>Agaves shared core prokaryotic and fungal taxa known to promote plant growth and confer tolerance to abiotic stress, which suggests common principles underpinning <jats:italic>Agave</jats:italic>–microbe interactions.</jats:p></jats:list-item> </jats:list> </jats:p>
