Characterization of nucleocapsid structure of BVs. (A–D) Cryo-EM images of nucleocapsids of AcMNPV. (A) Native nucleocapsids. (B) Partially uncoated nucleocapsids. The extruded fibrillar viral DNA is indicated with arrows. (C) Empty capsids without packaged viral DNA indicated with arrows. (D) “Relaxed” forms of nucleocapsids. The left panel shows the overall image of a relaxed NC. The panels at the right side show the detail of the spiral shapes of NC. (E) Distribution of the diameter of AcMNPV NC (n = 36, mean = 50.37 nm, SD = 2.24 nm and SeMNPV NC (n = 31, mean = 48.78 nm, SD = 0.93 nm). (F) Distribution of the length of AcMNPV NC (n = 34, mean = 311.5 nm, SD = 20.39 nm) and SeMNPV NC (n = 27, mean = 255.7 nm, SD = 28.31 nm). Significant differences between AcMNPV and SeMNPV are indicated (∗∗∗P < 0.0004 for NC diameter; P < 0.0004 for NC length). Scale bars represent 100 nm.
