Sac-like structure within which the ascospore is produced.
reproductive cell characterizing the ascomycetes where meiosis takes place followed by the internal formation of ascospores
The cell that develops after a fusion of nuclei of opposite mating type. In Neurospora crassa, the mature ascus is a narrow sac with the ascospores in a linear order reflecting the events of meiosis.
The sac-like structure in which ascospores are found. They vary in shape from narrow and elongate to nearly round. While the number of ascospores per ascus in usually 8, 1, 2, 4, 6, as well as numerous ascospores per ascus are also known.
The oval or cylindrical cell in which spores (typically 8) are produced in the sac fungi.
a specialized sexual reproductive cell found in the fertile area of the hymenium of all Ascomycetes. An ascus is typically club shaped and which forms internally 4 or 8 ascospores, usually in a row.
saclike cell in which ascospores (typically eight) are produced.
saclike structure in which ascospores are formed through sexual reproduction of ascomycetes
a tube-shaped vessel, a meiosporangium, which contains the sexual spores produced by meiosis
A sac-like structure containing four spores in S. cerevisiae Plural: asci.
a sac-like cell containing the ascospores cleaved from within by free cell formation after karyogamy (nuclear fusion) and meiosis. Eight ascospores typically are formed within the ascus, but this number may vary considerably.
Exterior-walled, flexible-floored sac beneath frontal shield of autozooid in ascophoran cheilostomes; encloses water-filled chamber opening at or near orifice to function in hydrostatic system; derived by infolding of part of frontal wall beneath gymnocyst or cryptocyst, or by overarching of frontal wall by umbonuloid shield and associated structures (Boardman & Cheetham, 1983). (Syn. compensation space)
a sac-like cell generally containing a definite number of ascospores, typically 8, formed after karyogamy and meiosis.
A saclike cell that gives rise to ascospore. Asci are characteristic of the Ascomycetes.
The structure that contains the four ascospores produced by a single meiosis of the yeast Saccharomyces cerevisiae.
Structure produced by sac fungi in which sexual ascospores develop.
a sac-like cell of an Ascomycete within which two haploid nuclei fuse, after which three divisions occur, two of them meiotic, resulting in eight ascospores.
(Pl. asci.) a sac-like cell of an ascomycete within which ascospores are formed.
A cell that is the site of meiosis and in which endogenous spores (usually meiospores but sometimes also ascoconidia) are formed. (Pl. asci.) ( 15)
Cell containing ascospores in Ascomycotina
a specialized sac-like cell where meiosis occurs and which encloses the ascospores
In fungi, a sac that encloses a tetrad or an octad of ascospores.
flexible sac beneath the frontal wall of ascophoran zooids.
(pl. asci): A sack-like cell of a hypha in which meiosis occurs and which contains the ascospores (usually eight in number). picture of ascus
the cylindrical or club-shaped spore-producing cell that characterises the Ascomycetes. Contains (usually 8) ascospores
A cell generally carrying a number of ascospores (typically eight) formed by free-cell formation - character of Ascomycota.
An ascus (plural asci) is the spore-bearing container produced in ascomycete fungi. Each ascus normally contains either four or eight ascospores, produced by a meiotic cell division followed, in some species, by a mitotic cell division. In some cases the asci are formed in a regular layer, the hymenium, in a fruiting body which is visible to the naked eye, here called an ascocarp or ascoma.
