Abstract Background Despite wealth of information generated on salt tolerance mechanism its basics still remain elusive. Thus there is a need of continued effort to understand the salt tolerance mechanism using suitable biotechnological techniques and test plants species to enable development of salt tolerant cultivars of interest. Therefore the present study was undertaken to generate information on salt stress responsive genes in a natural halophyte Suaeda maritima using PCR-based suppression subtractive hybridization PCR-SSH technique. Results Forward and reverse SSH cDNA libraries were constructed after exposing the young plants to 425 mM NaCl for 24 h. From the forward SSH cDNA library 429 high quality ESTs were obtained. BLASTX search and TIGR assembler programme revealed overexpression of 167 unigenes comprising 89 singletons and 78 contigs with ESTs redundancy of . Among the unigenes were found to be of special interest indicating novel function of these genes with regard to salt
