Figure 19.  This video clip shows successive optical sections from the surface down into the epidermal cells of a living silk infected by U. maydis. At this point, the cytoplasm from the infection hypha has moved from the surface down into the epidermal cell. The host cell is clearly still metabolically active; evidence of cytoplasmic streaming around the penetrating hypha can be seen. (Courtesy K.M. Snetselaar) BACK
