They represent a polyphyletic group with diverse evolutionary origin and are involved in a multitude of processes of vast ecological importance. Together with the prokaryotic blue-green algae (cyanobacteria), microalgae contribute to about half of the global carbon fixation (Field &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;1998&lt;/span&gt;; Brodie &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2017&lt;/span&gt;).&lt;/p&gt;\u0000&lt;p&gt;In the past decades, several algal genomes have been sequenced, leading to the development of genetically tractable microalgal models (Grossman, &lt;span&gt;2007&lt;/span&gt;; Brodie &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2017&lt;/span&gt;; Falciatore &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;). One of the first well-developed algal models is the green microalga &lt;i&gt;Chlamydomonas reinhardtii&lt;/i&gt; that was first isolated from a potato field in the USA (Harris, &lt;span&gt;1989&lt;/span&gt;). In its natural habitat, it is typically found in wet soil, coexisting with other microorganisms (Sasso &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2018&lt;/span&gt;). However, in laboratory settings, it is commonly cultivated axenically in liquid culture. The biciliate &lt;i&gt;C. reinhardtii&lt;/i&gt; cell has a cup-shaped chloroplast including a primitive visual system at its edge near the cell equator, called eyespot. Within the chloroplast, there is also a pyrenoid that contains RuBisCO and is surrounded by a starch sheet (Harris, &lt;span&gt;1989&lt;/span&gt;; Sasso &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2018&lt;/span&gt;). &lt;i&gt;Chlamydomonas reinhardtii&lt;/i&gt; reproduces asexually by mitosis in the form of haploid vegetative cells that have mating type plus or minus. Under unfavorable environmental conditions (lack of a nitrogen source), &lt;i&gt;C. reinhardtii&lt;/i&gt; initiates a sexual life cycle, allowing sexual crosses (reviewed in Sasso &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2018&lt;/span&gt;).&lt;/p&gt;\u0000&lt;p&gt;&lt;i&gt;Chlamydomonas reinhardtii&lt;/i&gt; serves as a model for studying different biological processes, such as photosynthesis and its acclimation, the function, biogenesis and length of cilia or light-driven processes (Grossman, &lt;span&gt;2000&lt;/span&gt;; Petersen &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2022&lt;/span&gt;; Sakato-Antoku &amp; King, &lt;span&gt;2022&lt;/span&gt;; Ishikawa &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;). The genome of &lt;i&gt;C. reinhardtii&lt;/i&gt; has been sequenced (Merchant &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2007&lt;/span&gt;) and recently a new version from a wild-type strain was released (Craig &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;). Additionally, many molecular tools are available for this alga as well as large-scale mutant libraries (Li &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2019&lt;/span&gt;; Schroda, &lt;span&gt;2019&lt;/span&gt;; Fauser &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2022&lt;/span&gt;).&lt;/p&gt;\u0000&lt;p&gt;Although there is a pressing demand for easily and rapidly cultivatable model algae in laboratory settings, we must be aware that the growth conditions in the laboratory do not reflect their predominant natural habitat.
