Histological aspects in the process of the vein clearing formation following tobacco mosaic virus infection are described. By using the leaf plastochron index which provides an indirect time-scale in vegetative shoot development of tobacco plants, it was evident that the vein clearing symptom appeared when the leaf in which the formation of intercellular spaces no longer occurred became invaded with the virus. This process to the formation of intercellular spaces reflected the duration of appearance of vein clearing, which is often only a temporary, early symptom. Development of the vein clearing symptom also appeared in the leaf in which cells contained the resting nuclei.
