Salinity is one of the major environmental constraints to plant productivity。Under stress condition， plants exhibit a variety of physiological and biochemical responses at cellular to whole-plants level。Plants evolve various adaptive strategies at molecular level to mitigate the damaging effect。Most of the strategies are involved in dynamic changes of protein abundance that can be best explored through proteomics。Alfalfa (Medicago sativa) is very promising forage crop native to Iran。To date， salinity-related proteomics resource of forage crops are limited。The main purpose of this study is to highlight the salinity-responsive proteomic responses in M。sativa in terms of salinity tolerance。In our proteomic analysis， total fifty eight protein spots were found to be modulated by at least 1。5 fold in at least one time points on 2-D gels。Total forty-two proteins were identified as salinity responsive。Broadly the identified proteins were primarily involved in cell membrane related， primary and secondary metabolism， redox regulation， antioxidant defense， and cytoskeleton related proteins。The primary and secondary metabolism was the biggest functional category that indicates energy production was largely affected by salinity stress。Interestingly， several antioxidantly related proteins were up-regulated in salinity response。Together these results provide new insights that may lead to molecular mechanisms of salinity stress-tolerance in alfalfa plant。
