A projection of 29 confocal optical sections taken at 0.2-µm intervals through the hyphal network in an inner cortical cell of a root of Medicago truncatula colonized by arbuscular-mycorrhizal fungi. The root section was stained with Texas-Red conjugated to wheat germ agglutinin, which binds to the surface of the hyphae. Confocal images by E. B. Blancaflor, L. Zhao, and M. J. Harrison.
