Riparian plants in arid areas are subject to frequent hydrological fluctuations induced through natural flow variation and water use by humans. Although many studies have focused on the success of Tamarix ramosissima Ledeb. in its invaded ranges, its major competitor in its home range, Populus euphratica Oliv., historically has dominated riparian forests where both species occur naturally. Thus...

The saline character of water imposes restrictions on plant growth and survival in the Taklamakan Desert, China. Experiments were conducted woody species, Tamarix ramosissima, Populus euphratica, Haloxylon ammodendron grown under different levels salinity to elucidate their adaptation a environment. H. accumulated large amounts Na+ Cl- leaves. P. euphratica restricted redundant transport shoots...

During the study on rust mycobiota of Central Alborz, several rust infected specimens belonging to Salicaceae family including Populus and Salix species were investigated. Populus nigra, P. euphratica, Saix alba and S. excelsa were infected by various Melampsora species. Uredinial (II) and telial (III) stages of rust were present on infected plants. According to morphological characters, five f...

Ecological restoration of degraded riparian Tugai forests in north-western China is a key driver to combat desertification in this region. Recent restoration efforts attempt to recover the forest along with its most dominant tree species, Populus euphratica. The present research observed the response of natural vegetation using an object based change detection method on QuickBird (2005) and Wor...

• Salinity causes osmotic stress and limits biomass production of plants. The goal of this study was to investigate mechanisms underlying hydraulic adaptation to salinity. • Anatomical, ecophysiological and transcriptional responses to salinity were investigated in the xylem of a salt-sensitive (Populus × canescens) and a salt-tolerant species (Populus euphratica). • Moderate salt stress, which...

Understanding which genes have evolved rapidly with the recent tree speciation in arid habitats can provide valuable insights into different adaptation mechanisms. We employed a comparative evolutionary analysis of expressed sequence tags (ESTs) from two desert poplars, Populus pruinosa and P. euphratica, which diverged in the recent past. Following an approach taken previously with P. euphrati...
