Cyanobacteria have an internal biological clock that rhythms their activities on a 24-hour cycle. Thanks to this finely regulated mechanism, these micro-organisms are able to anticipate day/night cycles. A study recently published in Scientific Reports looked at how this clock reacts when the temperature drops below 25°C, an important threshold for their physiology.
To find out more, take a look at :
- the news published on the CNRS Physique website,
- the scientific article in open access in Scientific Reports.
