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.

Registration for the upcoming 6th SPPS PhD Conference will start in February 2010. At that time, you will be able to register online on the conference's official homepage. Please remember, that SPPS may provide grants for PhD students to cover their expenses for active participation in SPPS Congresses. Please note, however, that a member can apply for a grant only if she/he has been a member of SPPS also during the previous year. For more information on the SPPS grants, please contact the Secretary General Anna Kärkönen. The conference will be held during 2-5 September 2010 in Espoo.
The SPPS PhD Conference is arranged every second year and alternates with the SPPS Congress, which is also biannual. They usually attract around 50 PhD students coming from primarily the Scandinavian countries but also include some participants from the Baltic countries, Europe and America. The venue circulates through the Nordic countries and a local organising committee is responsible for making a scientific programme of very high standards and including a number of internationally recognised invited speakers.
