Proteomic analysis of two dry bean market classes: white kidney and navy. (a) PC analysis of three white kidney bean cultivars, "blue triangles" and three navy bean cultivars, "red circles". (b) Hierarchical clustering displayed with heat map of densitometry values from 2 D gels comparing three white kidney bean and three navy bean cultivars. Each cell in the heat map represents one protein. Mean spot density for each protein or protein fragment was calculated across all cultivars and intensities relative to the mean were plotted using a blue to red color map to indicate a decrease or increase in intensity with respect to the calculated mean spot density. Cultivars studied are listed in the Materials and Methods section.
