Root?associated microbial communities play important roles in the process of adaptation plant hosts to environment stressors, and this perspective, microbiome halophytes represents a valuable model for understanding contribution microorganisms tolerance salt. Although considered as most promising halophyte candidate crop cultivation, Salicornia ramosissima is one least-studied species terms com...

To explore the roles of plasticity and genetic variation in the response to spatial and temporal climate variation, we established a common garden consisting of paired collections of native and introduced riparian trees sampled along a latitudinal gradient. The garden in Fort Collins, Colorado (latitude 40.6°N), included 681 native plains cottonwood (Populus deltoides subsp. monilifera) and int...
