Scandinavian research institute: The Global Plant Council - Research to save the planet BROWSE ISSUES NEWS FROM PHYSIOLOGIA PLANTARUM Published monthly on behalf of SPPS by Wiley-Blackwell. Changes in atmospheric CO2 affect respiration efficiency The increasing atmospheric have resulted in a general increase in photosynthesis and biomass, but less is known about how plants adapt to this environmental change in terms of respiration. Now, scientists at University of Illinois at Chicago have taken up this issue by growing Arabidopsis thaliana plants adapted to Pleistocene sub-CO2 levels of 200 µl/l at current 360 µl/l CO2. The results show that these plants exhibited reduced respiration as compared to plants adapted to ambient CO2. The lower respiration rate was, however, not associated with a corresponding reduction in nitrogen content of the tissues. The results suggest, that plants adapt to changes in atmospheric CO2 by adjusting mitochondrial energy coupling and activity of the so called alternative pathway, where photosynthate is consumed in a less energy efficient way leading to lower ATP production.

You can already now register online and in order to get the reduced early bird registration fee, you must do so before February 11th. The fee for FESPB members are 475 € (students 320 €), whereas non-members must pay 550 € or 370 €, repectively. After February 11th the fees wil be 550 € (students 375 €) for members and 620 € (students 425 €) for non-members. Another important date to remember is March 1st, which is the abstract submission deadline. In order to have the abstract published in the Abstract Book, you must pay the registration fee before March 10th. Each registered participant can submit only one abstract as presenting author, and the maximum length of the abstract text should not exceed 1500 characters. You can find more information about the XVIIth FESPB congress at the official homepage.
