Technical Abstract: Cryptic symbiotic microbes influence host adaptation by improving nutrient uptake or stress tolerance. Current technologies for increasing plant productivity, whether for food and fuel production or for restoration and remediation, often utilize approaches that bypass, rather than leverage, microbial influences. Such technologies are insufficient for reversing desertification and increasing vegetative production to meet the increased demands of expanding populations and changing climates. Improved understanding of host-microbe interactions across ecological gradients may facilitate technology development that harnesses microbial power to advance restoration, crop, and fuel production in extreme environments. The woody shrub genus, Atriplex , provides a useful model system in which to correlate microbial diversity with host adaptation to harsh arid and saline environments Atriplex species contain diverse microbial endophyte communities and are valued for forage, restoration, and remediation worldwide.Here we describe fungal and bacterial endophytes detected in micropropagated Atriplex canescens by microscopy, PCR, and pyrosequencing.
