What is the function of Disjunctor cell?

Glossary of Mycological Terms

Term	Definition
Dimorphic	Having two different morphological forms.
Disjunctor cell	An empty cell that fragments and/or undergoes lysis to release a conidium.
Dolipore septum	A characteristic septum found in the Basidiomycetes that flares out near the pore to form an elongate channel.

What is phialide mycology?

The phialide (/ˈfaɪəlaɪd/ FY-ə-lyde; Greek: phialis, diminutive of phiale, a broad, flat vessel) is a flask-shaped projection from the vesicle (dilated part of the top of conidiophore) of certain fungi.

What is Conidiogenous cell?

conidiogenous cell: any cell that produces or becomes a conidium. conidiophore: a specialized hypha or cell on which, or as part of which, conidia are produced. conidium (pl. conidia): an asexual, non-motile spore.

What is a Disjunctor?

Definition of disjunctor 1 : a device for disconnecting an electrical circuit. 2 : a small cellulose body interposed between the conidia of certain fungi that ultimately breaks down and sets them free.

What are Arthrospores?

Arthrospores are a very primitive spore type, formed by the breaking up or disarticulation of fungal mycelia. Many yeast-like fungi such as the genera Geotricum and Trichosporon form arthrospores. These organisms require a series of biochemical tests for definitive identification.

What are Conidiogenous cells?

What is a Hulle?

Hülle cells are characteristic structures normally produced by some species of the genus Aspergillus. These cells are associated with the cleistothecia of all ascogenous species of the Aspergillus nidulans group, abundantly occurring around it.

What is Annellophore?

Annellophores are hyaline or variously coloured and may be aggregated in penicillate heads, produced on synnemata or on tuberculariaceous stromata, in acervuli or in pycnidia.

Are Arthrospores asexual?

Asexual reproduction can occur either by central constriction of a parent cell to form two daughter cells or by spore formation. There are several types of spore formation. When hyphal fragementation occurs, the resulting spores are termed arthrospores.

What are mitospores and Meiospores?

The spores produced by mitosis are mitospores whereas the spore that gets produced by meiosis is meiospore. The mitospore possesses the same set of chromosomes as the parent body and the meiospores to show genetic variation and helps the species for their adaptation.

How are mitospores produced?

Mitospore formation Some fungi and algae produce mitospores through mitotic cell division within a sporangium. In fungi, such mitospores are referred to as conidia.

What is Metulae in fungi?

Definition of metula : one of the outermost branches of a conidiophore from which flask-shaped phialides radiate (as in molds of the genera Aspergillus and Penicillium)

What does promoting conidiogenesis mean?

Promoting conidiogenesis; (of fungal cells) producing conidia. 1960s; earliest use found in Nature: a weekly journal of science. From conidium + -o- + -genous.

What is a conidium in fungi?

A conidium ( pl. conidia ), sometimes termed an asexual chlamydospore or chlamydoconidium ( pl. chlamydoconidia ), is an asexual, non- motile spore of a fungus. The word conidium comes from the Ancient Greek word for dust, κόνις ( kónis ). They are also called mitospores due to the way they are generated through the cellular process of mitosis.

What type of conidia do phialides have?

They also have simple single-celled conidia (ameroconidia) in chains that were produced and attached in the basipetal succession of phialides, specialized conidiogenous cells giving the brush-like appearance of the species (Figure 3 (f)). nature of the conidiogenous cell and the presence or absence of chains of condia).
