AB  - Using the Affymetrix poplar genome array, we explored the leaf transcriptome of 
      salt-tolerant Populus euphratica Oliv. and salt-sensitive P. popularis 35-44 (P. 
      popularis) under control and saline conditions. Our objective was to clarify the 
      genomic differences in regulating K(+)/Na(+) and reactive oxygen species (ROS) 
      homeostasis between the two species. Compared to P. popularis, salt-tolerant P. 
      euphratica responses to salinity involved induction of a relatively larger number 
      of probesets after short-term (ST) exposure to 150 mM NaCl (24 h) and relatively 
      fewer probesets after a long-term (LT) exposure to salinity (200 mM NaCl, 28 
      days). Compared to P. popularis, leaves of the control P. euphratica plants 
      exhibited a higher transcript abundance of genes related to Na(+)/H(+) antiport 
      (Na(+)/H(+) antiporters, H(+) pumps) and K(+) uptake and transport. Notably, the 
      expression of these genes did not decrease (with a few exceptions) during salt 
      treatment. Regarding ROS homeostasis, P. euphratica exhibited rapid up-regulation 
      of a variety of antioxidant enzymes after exposure to ST salinity, indicating a 
      rapid adaptive response to salt stress. However, the effect of NaCl on 
      transcription in P. popularis leaves was more pronounced after exposure to 
      prolonged salinity. LT-stressed P. popularis up-regulated some genes mediating 
      K(+)/Na(+) homeostasis but decreased transcription of main scavengers of 
      superoxide radicals and H(2)O(2) except for some isoforms of a few scavengers. 
      Mineral and ROS analyses show that NaCl induced a marked increase of leaf Na(+) 
      and H(2)O(2) in LT-stressed plants of the two species and the effects were even 
      more pronounced in the salt-sensitive poplar. We place the transcription results 
      in the context of our physiological measurements to infer some implications of 
      NaCl-induced alterations in gene expression related to K(+)/Na(+) and ROS 
      homeostasis.
