Bean common mosaic virus (BCMV), the most common seed-borne pathogen in Phaseolus vulgaris L. is known to cause severe loss in productivity across the globe. In the present study, proteomic analyses were performed for leaf samples from control (healthy) and susceptible BCMV infected plants. The differential expression of proteins was evaluated using two-dimensional gel electrophoresis (2-DE). Approximately, 1098 proteins were spotted, amongst which 107 proteins were observed to be statistically significant with differential expression. The functional categorization of the differential proteins illustrated that they were involved in biotic/abiotic stress (18%), energy and carbon metabolism (11%), photosynthesis (46%), protein biosynthesis (10%), chaperoning (5%), chlorophyll (5%) and polyunsaturated fatty acid biosynthesis (5%). This is the first report on the comparative proteome study of compatible plant-BCMV interactions in P. vulgaris which contributes largely to the understanding of protein-mediated disease resistance/susceptible mechanisms.
