The three-dimensional structure of periderm tubes, which normally occur in the bark of intact Vitis vinifera L. stems, is described. Each tube, which possesses several layers of mature phellem cells, differentiated around an individual strand of secondary phloem fibres within the bark. Following these peridermenclosed strands for their full length revealed that at one or two points the strand passed through a sheet of periderm and was exposed to the surrounding atmosphere. The tubes of suberised phellern within the bark isolated these strands of air-dried fibres from the living parenchyma cells around them and thus protected the bark from desiccation and pathogen attack.

Nudaurelia capensis β virus (NβV) is an RNA virus of the South African Pine Emperor moth, Nudaurelia cytherea capensis (Lepidoptera: Saturniidae). The NβV capsid is a T = 4 icosahedron that contains 60T = 240 subunits of the coat protein (Mr = 61,000). A three-dimensional reconstruction of the NβV capsid was previously computed from visions embedded in negative stain suspended over holes in a carbon film. We have re-examined the three-dimensional structure of NβV, using cryo-microscopy to examine the native, unstained structure of the virion and to provide a initial phasing model for high-resolution x-ray crystallographic studiesNβV was purified and prepared for cryo-microscopy as described. Micrographs were recorded ∼1 - 2 μm underfocus at a magnification of 49,000X with a total electron dose of about 1800 e-/nm2.
