The nearly ubiquitous bacterial second messenger cyclic di-GMP is involved in a
multitude of fundamental physiological processes such as sessility/motility
transition and the switch between the acute and chronic infection status,
combined with cell cycle control. The discovery of cyclic di-GMP, though, has
been an example par excellence of scientific serendipity. We recapitulate here
its years-long discovery process as an activator of the cellulose synthase of the
environmental bacterium Komagataeibacter xylinus and its consequences for
follow-up research. Indeed, the discovery of cyclic di-GMP as a ubiquitous second
messenger contributed to the change in perception of bacteria as simple
unicellular organisms just randomly building-up multicellular communities.
Subsequently, cyclic di-GMP also paved the way to the identification of other
pro- and eukaryotic cyclic dinucleotide second messengers.
