The circadian clock and darkness control natural competence in cyanobacteria

Please add some short info on this study to the article and/or other articles where it's relevant (see the wikilinks below).

In the new study, the researchers identified the DNA uptake machinery in the cyanobacterium Synechococcus elongatus and discovered that the internal circadian clocks within their cells prevent DNA uptake early in the day and enhance the process early at night. They had predicted that clock-mediated expression of certain dusk-peaking, dark-induced genes is central for taking up DNA from the environment. They found that when darkness occurs at the time the cells' internal clock tells them it's dusk, DNA uptake and incorporation increase dramatically. In contrast, darkness at times that do not match the internal clock time fails to provide a boost in DNA uptake and incorporation.

As for why early DNA uptake is discouraged and late is enhanced, scientists aren't quite sure. They are testing hypotheses such as whether it may be helpful to avoid taking up potentially dangerous DNA when viruses are more prevalent, which in some environments is during the day.

I'm asking about it because I read a report about it due to writing for the 2020 in science article.
