Diatoms play an important role in water quality and in the
global climate. They generate about one fourth of the oxygen in the Earth’s
atmosphere and perform around one-quarter of the global CO2 assimilation, i.e.
they convert carbon dioxide into organic substances. Their light receptors are
a crucial factor in this process. Researchers at the Leipzig University and the
Helmholtz Centre for Environmental Research have now discovered that blue and
red light sensing photoreceptors control the carbon flow in these algae. These
results have been recently published by the scientists in the well-known online
trade journal, PLOS ONE.
