Abstract

Salinity is a major abiotic stress that negatively affect plant growth, survival and productivity. In the present study we have identified six putative salt inducible Arabidopsis ortholog genes from chickpea genome belonging to different functional categories as per gene ontology classification. Salt responsive expression of genes was validated by semiquantitative RT-PCR which revealed their possible role in salt stress response. Comparison of promoter regions of these six genes of chickpea with promoter region of 44 putative salt responsive genes of Arabidopsis revealed three conserved motifs of different lengths specific to chickpea genes. The genes identified in this study may serve as promising candidates in studies of salt tolerance mechanisms of chickpea.
