Blastoconidium

Part of speech: noun

Definitions

1. A type of asexual fungal spore produced by budding from a parent cell, commonly involved in reproduction and dispersal of certain yeasts and fungi
2. An asexual reproductive structure formed by the outward growth and separation from a fungal cell, facilitating propagation and spread in fungi such as yeasts
3. A budded fungal spore generated through mitotic division for nonsexual reproduction, playing a key role in the lifecycle and distribution of some yeast species and fungi

Etymology: Blastoconidium is a technical coinage built from two parts that are both Greek-derived. "Blasto-" comes from Greek "blastos," meaning sprout, bud or germ, and it appears in biology wherever something develops from an early growing point. "Conidium" comes from Greek "konis," meaning dust, and was adopted into scientific Latin for the spores that fungi produce in the open air. Joining the two gives a spore that grows out as a bud. The word therefore describes a process as much as an object. In yeasts, a new cell pushes out from the parent cell's surface, swells, and eventually breaks away to become an independent organism. The "bud" in the name is literal: the structure is named for the sprouting that produces it, not for the dust-like spores from which the second half takes its name.

Synonyms: conidium, fungal spore, asexual spore
