Air purification: Plant hemoglobin proteins help plants fix atmospheric nitric oxide

(Helmholtz Zentrum München – German Research Center for Environmental Health) Scientists of Helmholtz Zentrum München have now discovered that Arabidopsis thaliana plants can fix atmospheric nitric oxide with the aid of plant hemoglobin proteins. Using this previously unknown mechanism, these plants can contribute to the improvement of air quality. The results of the research have now been published in the journal Plant, Cell & Environment.
