Hypha

Hyphae ( from Greek Ὑφή, tissue ' ), the filamentous cells of fungi and streptomycetes. From them is in filamentous fungi, the entire mushroom, the mycelium, fruiting bodies, and the fungal proportion of mycorrhizas of tree fungi. Some usually unicellular yeasts such as Saccharomyces cerevisiae can also form hyphae under certain conditions. The hyphae are divided by partitions which run through the hyphae transversely into sections. These walls are known as septa.

In symbiotic filamentous fungi in or on plants, the direct contact zone between fungus and plant always looks similar, regardless of the structures of the different symbioses: fungal and plant cell always remain separated from each other, even if the fungus grows into individual plant cells. Between the cytosol of the fungus and the plant thus always remain two membranes, from a fungus, from the plant. These membranes have special channels, which control the transport of various materials. The two membranes of fungi and plants are also always separated by a layer of extracellular matrix. Said layer belongs to the apoplast, and can be used both by the fungus, and the plant stem. It is often very thin and permeable, the substances to be transported easily overcome by diffusion.
