Salt stress is a major constrain to the productivity of nutritionally rich pigeonpea, an important legume of SE Asia and other parts of the world. The present study provides a comprehensive insight on integrated proteomic and transcriptomic analysis of root and shoot tissues of contrasting pigeonpea varieties (ICP1071- salt-sensitive; ICP7- salt-tolerant) to unravel salt stress induced pathways. Proteome analysis revealed 82 differentially expressed proteins (DEPs) with ≥±1.5 fold expression on 2-Dimensional (2D) gel. Of these, 25 DEPs identified through MALDI-TOF/TOF were classified using Uniprot software into functional categories. Pathways analyses using KAAS server showed the highest abundance of functional genes regulating metabolisms of carbohydrate followed by protein folding/degradation, amino acids and lipids. Expression studies on six genes (triosephosphate isomerase, oxygen evolving enhancer …
