The arbuscules of mutualistic mycorrhizal fungi serve a similar function in nutrient exchange, so are important in assisting nutrient and water absorption by plants. Ectomycorrhizal extramatrical mycelium greatly increases the soil area available for exploitation by plant hosts by funneling water and nutrients to ectomycorrhizas , complex ...
The contents of the spore are then mobilized into the developing appressorium, a septum develops at the neck of the appressorium, and the germ tube and spore collapse and die. As the appressorium matures, it becomes firmly attached to the plant surface and a dense layer of melanin is laid down in the appressorium wall, except across a pore at ...
Mycelium is an important food source for many soil invertebrates. They are vital to agriculture and are important to almost all species of plants, many species co-evolving with the fungi. Mycelium is a primary factor in some plants' health, nutrient intake and growth, with mycelium being a major factor to plant fitness.
A coral septum is one of the radial calcareous plates in the corallites of a coral. [18]Annelids have septa that divide their coelom into segmented chambers. [19]Many shelled organisms have septa subdividing their shell chamber, including rhizopods, cephalopods and gastropods, the latter seemingly serving as a defence against shell-boring predators.
A septum develops by gradual inward extension until it separates the terminal gametangia from the progametangial base. At this point the zygophore is then called the suspensor. Vesicles accumulate at the fusion septum at which time it begins to dissolve. A little before the fusion septum completely dissolves, the primary outer wall begins to ...

Septins are highly conserved between different eukaryotic species. They are composed of a variable-length proline rich N-terminus with a basic phosphoinositide binding motif important for membrane association, a GTP-binding domain, a highly conserved Septin Unique Element domain, and a C-terminal extension including a coiled coil domain of ...
