In mycology, a stolon is defined as an occasionally septate hypha, which connects sporangiophores together. Root-like structures called rhizoids may appear on the stolon as well, anchoring the hyphae to the substrate. The stolon is commonly found in bread molds, and are seen as horizontally expanding across the mold.
Rhizoids are protuberances that extend from the lower epidermal cells of bryophytes and algae. They are similar in structure and function to the root hairs of vascular land plants . Similar structures are formed by some fungi .
stolon A horizontal hypha that sprouts where it touches the substrate, in Mucorales. Connects groups of rhizoid s. [368] striate Having minute radiating lines or ridges, such as the margin of a pileus. [369] stroma Close-up of a stroma of ergot, an ascomycete. pl. stromata
A hypha (from Ancient Greek ὑφή (huphḗ) 'web'; pl.: hyphae) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. [1] In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium .
Sporangiophores arise among distinctive, root-like rhizoids. In sexual reproduction, a dark zygospore is produced at the point where two compatible mycelia fuse. Upon germination, a zygospore produces colonies that are genetically different from either parent. Rhizopus oligosporus is used to make tempeh, a fermented food derived from soybeans.
Underground stems are modified plant parts that derive from stem tissue but exist under the soil surface. [1] They function as storage tissues for food and nutrients, facilitate the propagation of new clones, and aid in perennation (survival from one growing season to the next). [2]
Stolon – A branch that forms near the base of the plant, grows horizontally, and roots and produces new plants at the nodes or apex. Stoloniferous – plants producing stolons. Semi-erect – Not growing perfectly straight. Suffrutescent – somewhat shrubby, or shrubby at the base. Upright – Growing upward.
Rhizopus species periodically produce rhizoids, which anchor it to the substrate and unbranched aerial sporangiophores. [8] Sporangiophores of R. stolonifer can be up to 2.5 mm long and about 20 μm in diameter. [6] The spores are shaped differently depending on the available nutrients. They can be ovate, polygonal or angular. [6]
