Abstract. X-ray fiber diffraction analysis of tobacco mosaic virus (TMV) has led to the building of a molecular model of the intact virus, based on a map at 3.6 Å resolution derived from five separated Bessel orders. This has been made possible by advances in the solution of the fiber diffraction phase problem.
02/07/2015 · Tobacco mosaic virus (TMV) is named for one of the first plants in which it was found in the 1800s. However, it can infect well over 350 different species of plants. TMV is made up of a piece of nucleic acid (ribonucleic acid; RNA) and a surrounding protein coat. The complete virus is a submicroscopic, rigid, rod-shaped particle.
