Abstract Identifying suitable habitats for endangered species is critical in order to promote their recovery. However, conventional distribution models (SDMs) need large amounts of labeled sample data learn the relationship between and environmental conditions, are difficult fully detangle role environment species, which very sparsely distributed have heterogeneity. This study’s first innovatio...

Leaf functional traits allow plant survival and maintain their ecosystem function. Salinity affects leaf traits, but coordination among is poorly known may depend on salt severity. To increase our understanding of the under stress, we determined hydraulic, gas exchange, physiological biochemical parameters in Populus euphratica Oliv. ( P. ) grown salinity treatments, as well exchange different ...

In arid and semi-arid environments, desert vegetation plays an important role in preventing soil erosion by wind helps maintain the stability of oasis ecosystems. Four types typical vegetation, namely Populus euphratica, Haloxylon ammodendron, Nitraria sibirica, Halostachs caspica, corresponding to different habitats (i.e., river bank, sand dune, desert, salt marsh) were chosen as model this re...

Populus euphratica Olivier is known to exist in saline and arid environments. In this study we investigated the physiological mechanisms enabling this species to cope with stress caused by salinity. Acclimation to increasing Na+ concentrations required adjustments of the osmotic pressure of leaves, which were achieved by accumulation of Na+ and compensatory decreases in calcium and soluble carb...

Na+,K+/H+ antiporters are H+-coupled cotransporters that are crucial for cellular homeostasis. Populus euphratica, a well-known tree halophyte, contains six Na+/H+ antiporter genes (PeNHX1-6) that have been shown to function in salt tolerance. However, the catalytic mechanisms governing their ion transport remain largely unknown. Using the crystal structure of the Na+/H+ antiporter from the Esc...
