Callose in different tissues of plants following inoculation with SMV. A Fluorescence from stained callose in leaf vein of Wuxing 2 frictionally inoculated with N3; B micrograph of A under transmission light; C Fluorescence from stained callose in petiole of Wuxing 2 frictionally inoculated with N3; D micrograph of C under transmission light; E callose was not detectable in stem of Wuxing 2 frictionally inoculated with N3; F micrograph of E under transmission light; G callose was not detectable in vein of Wuxing 2 simulating inoculated; H micrograph of (G) under transmission light; I callose was not detectable in petioles of Wuxing 2 simulating inoculated; J micrograph of (I) under transmission light; K: callose was not detectable in stems of the Wuxing 2 inoculated with water; L micrograph of K under transmission light; a, c, e, g, i, k: enlarged pictures of the areas labelled with the arrows in picture (A, C, E, G, I, K)
