A blastoconidium (plural blastoconidia) is an asexual holoblastic conidia formed through the blowing out or budding process of a yeast cell, which is a type of asexual reproduction that results in a bud arising from a parent cell. [1] [2] The production of a blastoconidium can occur along a true hyphae, pseudohyphae, or a singular yeast cell. [3]
For example, the small bulb-like projection coming out from the yeast cell is known as a bud. Since the reproduction is asexual, the newly created organism is a clone and, excepting mutations, is genetically identical to the parent organism. Organisms such as hydra use regenerative cells for reproduction in the process of budding.
A blastospore is an asexual fungal spore produced by budding. Produced by fungi within the phylum Glomeromycota and others. It is also known as a blastoconidium (plural = blastoconidia). An example of a fungus that forms blastospores is Candida albicans.
Budding is also known on a multicellular level; an animal example is the hydra, [10] which reproduces by budding. The buds grow into fully matured individuals which eventually break away from the parent organism. Internal budding is a process of asexual reproduction, favoured by parasites such as Toxoplasma gondii.
The asexual, all-female whiptail species Aspidoscelis neomexicanus (center), which reproduces via parthenogenesis, is shown flanked by two sexual species having males, A. inornatus (left) and A. tigris (right), which naturally hybridized to form A. neomexicanus.
The budding yeast-like cells produced during the asexual stage are ellipsoidal to subcylindrical and 8–25 × 2–5.5 μm. They can occur singly or in pairs. They can occur singly or in pairs. [ 1 ] [ 6 ] The ballistoconidia are kidney-shaped and can range in size from 6–18 × 2.5–7.0 μm.
One example depicted here is quaking aspen. Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without a mate is known as parthenogenesis.
Asexual reproduction in sponges occurs via budding, either by external or internal buds. The internal buds are called gemmules. The internal buds are called gemmules. Only endogenous types of buds develop into new sponges.
