Dinoflagellates play crucial roles in aquatic ecosystems, particularly as major contributors to harmful algal blooms. They can enter a dormant stage, known as the resting cyst stage, that allows them to survive for extended periods—up to 150 years—in marine sediments. This dormancy is essential for their annual population dynamics, blooming cycles, and geographic expansion.

Researchers at the VIB-KU Leuven Center for Microbiology and the VIB-KU Leuven Center for Brain & Disease Research have revealed a mechanism involving protein aggregation that allows bacteria to enter a dormant state, a phenomenon that is associated with the persistence of infections and the challenge of antibiotic resistance. Their study is published in the journal Nature Communications.

Most Life on Earth is Dormant, After Pulling an ‘Emergency Brake’
Many microbes and cells are in deep sleep, waiting for the right moment to activate. Biologists discovered a widespread protein that abruptly shuts down a cell’s activity — and turns it back on just as fast.
"Bears hibernate. Herpes viruses lysogenize. Worms form a dauer stage. Insects enter diapause. Amphibians aestivate. Birds go into torpor. All of these are words for the exact same thing: a dormant state that organisms can reverse when conditions are favorable."
It's about survival...Fascinating discovery. Now, take a nap!
"Researchers recently reported the discovery of a natural protein, named Balon, that can bring a cell’s production of new proteins to a screeching halt. Balon was found in bacteria that hibernate in Arctic permafrost, but it also seems to be made by many other organisms and may be an overlooked mechanism for dormancy throughout the tree of life."

In perennial woody plants, bud endodormancy is crucial for survival under adverse environmental conditions in winter, such as low temperature (LT) and dehydration stress. To break bud dormancy is essential for the resumption of bud growth and flowering. Tree peony (Paeonia suffruticosa Andr.), belonging to the section Moutan of the genus Paeonia and family Paeoniaceae, is famous for high ornamental and medicinal value and is also known as a newly cultivated oil plant.
