- Karyogamy takes place in the young ascus soon after the septa are formed in the hook, thus ending the dikaryotic phase.
- Members of the phylum are simple in form, their hyphae lacking septa, and with simple fruiting bodies.
- The fascia (false or surgical capsule) sends fibrous septa into the gland substance, dividing it into numerous lobules.
- The function of these septa is to restrict the rotatory displacement of the brain.
- It is covered by the pia mater, which sends septa into the gland, dividing it into incomplete lobules (Pineal 1).
- Am J Bot 49: 86–94. Find this article online Bracker CE, Butler EE (1963) The ultrastructure and development of septa in hyphae of Rhizoctonia solani.
- Most annelids have a pair of coeloms (body cavities) in each segment, separated from other segments by septa and from each other by vertical mesenteries.
- An electron-dense, spherical body found in the hyphae of Ascomycota and many Deutromycetes; Woronin bodies are usually concentrated near septa.
- The hyphae of Ascomycota have bilayered walls with primary septa at regular intervals along the hypha.
- Acanthostigma multiseptatum can be distinguished in having longer asci and longer ascospores with more septa.
- Acanthostigma septoconstrictum differs in having longer setae and asci and broader, asymmetrical ascospores that are constricted at their septa.
- The fascia is called the posterior crural fascia, and it sends two septa to the fibula: anterior and posterior intermuscular septa.
- Perforated cross walls or septa.
- Subcylindrical hyphal tips form the palisades, born by subhymenial hyphae, hyphae transmit the palisades, dolipore complexes are visible at septa.
- Muriform: A conidium with both longitudinal and transverse septa.
- The septa that cut off the asci & conidia are initially perforated like all other septa, but later they often become blocked.
- Dikaryan hyphae are also septate - they have cross-walls called septa at regular intervals.
- The most common isolated species is P. chartarum and its spores have both longitudinal and transverse septa.
- In contrast, septa of the Agaricomycotina are relatively complex.
- The dolipore septa in the higher Basidiomycota (i.e., Agaricomycotina) are associated with septal pore caps.
- If the mycelia do not have septa, they are called coenocytic (non-septate).
- We have shown here that Woronin bodies in the rice blast fungus M. grisea are present adjacent to septa in mycelia, germ tubes, and infection hyphae.
- Mycelia of higher fungi consist of interconnected hyphae that are compartmentalized by septa.
- Zygomycete hyphae are coenocytic, with septa found only in reproductive structures.
- Vegetative cells in the Basidiomycota have septa and the formation and structure of those septa is diagnostic for some taxa.
- Types Classification based on cell division Septate (with septa) Aspergillus[ 3] and many other species have septate hyphae.
- PHRAGMOSPORE - a spore which has two or more transverse septa; septa appearing like the rungs of a ladder.
- In many species of fungi, hyphae are divided into sections by cross walls called septa.
- From time to time, hyphae develop reproductive structures that are partitioned from the hypha by hole less septa.
- Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa.
- As a hypha extends, septa may be formed behind the growing tip to partition each hypha into individual cells.
- The hyphae are coenocytic, with septa found only where reproductive cells are formed.
- Primitive fungi have few or no septa, so each organism is essentially a giant multinucleate supercell; these fungi are described as coenocytic.
- In the primitive or lower fungi, the mycelium consists of a continuous mass of cytoplasm and nuclei unbroken by septa (coenocytic).
- In the case of high temperature, septa opened again when the mycelium was placed back to the normal growth temperature.
- The liver-biopsy specimen in this case (Figure 1) shows established cirrhosis with nodular transformation of the hepatic parenchyma and fibrous septa.
- Coenocytic mycelium with septa separating the reproductive structures; rhizoids are formed by the hyphae at intervals of the growing stolons (hyphae).
- The septa separating the cells are complete and there is no cytoplasmic connection, as is found in most true septate hypha.
