| 英文摘要 | Male and female poplar (Populus cathayana Rehd.) cuttings respond differently to salinity stress. To understand these differences better, comparative morphological, physiological, and proteomics analyses were performed. Treatments with different concentrations of NaCl applied to male and female poplar cuttings for 4 weeks showed that females reacted more negatively at the morphological and physiological levels than did males, visible as shriveled leaves, decreased growth, lowered photosynthetic capacities, and greater Na+ accumulation. The proteome analysis identified 73 proteins from 82 sexually related salt-responsive spots. They were involved in photosynthesis, protein folding and assembly, synthesis and degradation, carbon, energy and steroid metabolism, plant stress and defense, redox homeostasis, signal transduction, and so forth. The sex-related changes of these proteins were consistent with the different morphological and physiological responses in males and females. In conclusion, the higher salt resistance of male P. cathayana cuttings is related to higher expression and lower degradation of proteins in the photosynthetic apparatus, more effective metabolic mechanism and protective system, and greater capacity of hydrogen peroxide scavenging. This research allows us to further understand the possible different management strategies of cellular activities in male and female Populus when confronted by salt stress. |
