  Kenaf is a member of the Hibiscus in the Malvaceae family and owns the characteristics of fast growing,high-yield,strong stress resistance and adaptability.We measured changes in the proteome of kenaf seedlings that were exposed to salinity (70,140,and 200 mM NaCl) using two-dimensional gel electrophoresis (2-DE) via matrix-assisted laser-desorption ionization-time of mass spectrometry (MALDE-TOF/MS).Forty-two protein spots were significantly altered by exposure to the salinity environment.Among them,6 protein spots were down-regulated and 36 protein spots were up-regulated.These proteins were associated with a variety of functions,including energy and material metabolism,protein metabolism,photosynthesis,defense&ROSscavengers,transport and coenzyme metabolism.
