Accommodation structures formed by filamentous microbes in Nicotiana benthamiana roots. Phytophthora palmivora projects digit-like haustoria into root cells that are surrounded by plant endoplasmic reticulum (labeled using green fluorescent protein, GFP). Arbuscular mycorrhizal (AM) fungi form arbuscules, visualized using a plant membrane-associated GFP fusion protein.
