NEWS: The end of being single - for green algae

ChemBioSys publication:

Bacterial marginolactones lead to the aggregation of algal cells to gloeocapsoids

Under the influence of marginolactones, two or more cells of the green alga Chlamydomonas reinhardtii form so-called gloeocapsoids that are surrounded by an outer matrix. Source: Mario Krespach/Leibniz-HKI.
Marginolactones – natural products from soil bacteria – trigger the formation of a previously unknown multicellular state for the green alga Chlamydomonas reinhardtii, which usually is unicellular. The emergence of multicellular organisms represents an essential step in the development of animals and plants. But how did unicellular organisms become permanently multicellular? A possible piece of the puzzle of these complex processes has now been deciphered by ChemBioSys
