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...

A PP2C homolog gene was cloned from the drought-treated cDNA library of Populus euphratica. Multiple sequence alignment analysis suggested that the gene is a potential ortholog of HAB1. The expression of this HAB1 ortholog (PeHAB1) was markedly induced by drought and moderately induced by ABA. To characterize its function in ABA signaling, we generated transgenic Arabidopsis thaliana plants ove...

Populus euphratica is the only tall tree species that adapts to desert environment. It has strong drought tolerance and subject of extreme concern at home abroad. After 30 years development, scope research on very extensive, but content not yet been crystalized into a mature field, directions abroad differ. In this study, we retrieved references ‘P. euphratica’ published from 1992 2022 in both ...
