Reproduction of Radiococcus and Tetracoccus by forming 4 autospores within a single cell
Autospores are a type of spores that are produced by algae to enable asexual reproduction and spread. They are non-motile and non-flagellated aplanospores that are generated within a parent cell and have the same shape as the parent cell before their release.[1] Autospores are also known as resting spores.[2] Algae primarily use three different types of spores for asexual reproduction - autospores, zoospores, and aplanospores.[3] Autospores occur in several groups of algae, including Eustigmatophyceae, Dinoflagellates, and green algae. One example of a colonial alga that produces autospores is Dichotomococcus. This alga generates two autospores per reproducing cell, and the autospores escape through a slit in the cell wall and remain attached to the mother cell.[4] Some study on autospores and algae in general include looking into its use for biofuel, animal feed, food supplements, nutraceuticals, and pharmaceuticals.[5]
