A sensor for nitrogen could be hidden behind the extension of an enzyme for the breakdown of starch. If this sensor detects a high level of nitrogen, algal growth switches into turbo mode.

Living organisms consist to a large extent of carbon (C) and nitrogen (N) compounds. These have to be taken in with food or, in the case of plants, produced through photosynthesis. A previously mysterious extension of a starch-degrading enzyme in algae could be a kind of sensor to determine how much nitrogen is currently available. If there is plenty of it, the algal cells quickly release many building blocks for their growth. ...
