AbstractSalinity is a major abiotic stress that inhibits plant growth and development. Plants have evolved complex adaptive mechanisms that respond to salinity stress. However, an understanding of how plants respond to salinity stress is far from being complete. In particular, how plants survive salinity stress via alterations to their intercellular metabolic networks and defense systems is largely unknown. To delineate the responses of Nitraria sphaerocarpa cell suspensions to salinity, changes in their protein expression patterns were characterized by a comparative proteomic approach. Cells that had been treated with 150mM NaCl for 1, 3, 5, 7, or 9days developed several stress-related phenotypes, including those affecting morphology and biochemical activities. Of similar to 1100 proteins detected in 2-DE gel patterns, 130 proteins showed differences in abundance with more than 1.5-fold when cells were stressed by salinity. All but one of these proteins was identified by MS and database searching. The 129 spots contained 111 different proteins, including those involved in signal transduction, cell rescue/defense, cytoskeleton and cell cycle, protein folding and assembly, which were the most significantly affected. Taken together, our results provide a foundation to understand the mechanism of salinity response. (C) 2012 Elsevier B.V. All rights reserved.
