Extracellular matrix (ECM) is the unique organelle that perceives stress signals and reprograms molecular events of host cell during patho‐stress. However, our understanding of how ECM dictates plant immunity is largely unknown. Vascular wilt caused by the soil borne filamentous fungus Fusarium oxysporum is a major impediment for global crop productivity. To elucidate the role of ECM proteins and molecular mechanism associated with cell wall mediated immunity, the temporal changes of ECM proteome was studied in vascular wilt resistant chickpea cultivar upon F. oxysporum infection. The 2DE protein profiling coupled with mass spectrometric analysis identified 166 immune responsive proteins (IRPs) involved in variety of functions. Our data suggest that wall remodeling; protein translocation, stabilization, and chitin triggered immunity; and extracellular ATP signaling are major players in early, middle, and later phases of ECM signaling during fungal attack. Furthermore, we interrogated the proteome data using network analysis that identified modules enriched in known and novel immunity‐related prognostic proteins centered around nascent aminopolypeptide complex (NAC), amine oxidase, thioredoxin, and chaperonin. This study for the first time provides an insight into the complex network operating in the ECM and impinges on the surveillance mechanism of innate immunity during patho‐stress in crop plant.
