Conifer needles consume oxygen when times are hard

Plants give us oxygen through photosynthesis – this is commonly taught in school. An international research team has now shown that particularly in early spring when low temperatures coincide with high light, conifer needles consume – not produce – oxygen by using an ancient adaptive mechanism. This study was published on 15.06.2023 in the international journal Nature Communications (IF: 17.69).

The international team of scientists includes researchers from Umeå University and Uppsala University, Sweden, the University of Oxford, UK, and the Institute of Biophysics and Biomedical Engineering, Bulgarian Academy of Sciences, Sofia (Bulgaria).
