TMV SAXS data. a SAXS curve of TMV (black dots) obtained during a standard exposure with fit to a three shell cylinder model (orange line). Inlay: Cross-sectional Guinier plot and fit. b Radial pair distance distribution function of TMV using the virus diameter found by AFM as constrained for D _max . c Schematic of the three-shell electron density distribution used as a model in a). d Atomistic model of the TMV cross-section with the RNA in orange. Based on pdb entry 1VTM. e SAXS data for different exposures time: standard, 5 min and 30 min exposures are plotted in blue, red and green, respectively
