Spores form a part of the life cycles of a diverse range of organisms such as many bacteria, plants, algae, fungi and some protozoa. In Saccharomyces cerevisiae (Kingdom Fungi), the set of early genes activating sporulation is induced by Ime1 (Inducer of Meiosis 1) and a regulator of middle genes is Ndt80p. [ 4 ]
The term spore derives from the ancient Greek word σπορά spora, meaning "seed, sowing", related to σπόρος sporos, "sowing", and σπείρειν speirein, "to sow".

Gram stain of Candida albicans from a vaginal swab, showing hyphae, and chlamydospores, which are 2–4 μm in diameter.. A chlamydospore is the thick-walled large resting spore of several kinds of fungi, including Ascomycota such as Candida, [1] Basidiomycota such as Panus, [2] and various Mortierellales species. [3]
Small acid-soluble proteins (SASPs) are found in endospores. These proteins tightly bind and condense the DNA, and are in part responsible for resistance to UV light and DNA-damaging chemicals. [3] Visualising endospores under light microscopy can be difficult due to the impermeability of the endospore wall to dyes and stains. While the rest of ...
