Laboratoř fotosyntézy
Skupina Ondřeje Prášila
I study a simple question that turns out to be surprisingly nontrivial:
For more than a century, since Charles Darwin and Ernst Haeckel, intracellular crystals were often regarded as passive waste products or cellular curiosities. My research has shown that these structures can serve as nutrient reservoirs, optical devices, regulators of metabolism, and potentially key players in global biogeochemical cycles.
By combining protistology, spectroscopy, microscopy, genetics, structural biology, photonics, and environmental biology, I investigate the formation, function, and evolution of biogenic crystals across microbial eukaryotes.
genes → molecular self-assembly → crystal formation → cell physiology → ecosystems → global biogeochemical cycles and Earth system processes
By understanding why cells build crystals, we may uncover previously hidden principles that shape life across scales, from molecule to structure to organelle to ecosystems
We showed that guanine crystals function as photonic mirrors in microbial eyespots. This discovery opened a completely new direction at the interface of cell biology, optics, and materials science.
víceUnexpected localization in chloroplasts rather than specialized acidocalcisomes known from other species, polyphosphate could be one of the major adaptation advantages in the terrestrialization process of zygnematophytes, the sister group of land plants.
víceWe discovered massive accumulation of barium and strontium in marine diplonemids.

We contributed to the discovery that guanine crystals serve as dynamic nitrogen reserves in microalgae.
víceWe demonstrated that purine crystals are widespread throughout eukaryotes and likely more abundant than previously recognized inorganic biominerals.
