    Cross-kingdom global proteomics reveals specific modulation of disease signaling in multi-host fungal pathogen infection in chickpea and worm

    An interconnected loop of messages and counter-messages determine the outcome of host-pathogen interactions. Multihost pathogenicity across plants and animals, particularly nematode, is a major source of new infectious diseases. Fusarium oxysporum, a multihost pathogen, causes vascular wilt in chickpea and fusariosis in worm and humans. To comprehend Fusarium-responsive multihost pathogenicity, we temporally profiled cross-kingdom species, chickpea and worm using SWATH-mass spectrometry. Morphological analyses revealed that increased wilting and intestinal disintegration elicits a disease response in chickpea and worm. Peptide-spectrum library consisted of 5629 and 3138 proteins from Fusarium infected chickpea and worm, respectively. SWATH analysis identified 1573 and 2249 disease-responsive chickpea (CaDRPs) and worm proteins (CeDRPs) linked to diverse organs, organelles, and functionality. Pairwise comparisons; over-representation analysis between time, treatment, and organism; wilt, and fusariosis diseasome revealed common and unique modules. CaDRPs involved in preformed defense, biomolecule synthesis, phytohormone regulation, ser/thr kinase, and ATP signaling have perturbed interactions and functions, majorly in chloroplast. CeDRPs linked to the cuticular support, muscle organization, neuronal information, intestinal metabolism, G-protein, and notch signaling showed a deregulated function, especially in the cytoplasm. Common biological processes, included primary metabolism, ribosome biogenesis, calcium signaling, and proteostasis. Our data provide first evidence of translational plasticity in the Fusarium diseasome providing novel insights into multihost pathogenesis.

    Quantitative extracellular matrix proteomics suggests cell wall reprogramming in host-specific immunity during vascular wilt caused by Fusarium oxysporum in chickpea
    (John Wiley & Sons, 2017) Elagamey, Eman; Narula, Kanika; Sinha, Arunima; Ghosh, Sudip; Abdellatef, Magdi A.E.; Chakraborty, Niranjan; Chakraborty, Subhra
    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 2-DE 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; 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.
