Changes in Photosynthetic Activity and Export of Carbon by Overexpressing a Maize Sucrose-Phosphate Synthase Gene under Elevated C02 in Transgenic Rice

open access: yesPlant Production Science, 2003
To investigate whether increased sucrose-phosphate synthase (SPS) activity alters photosynthetic activity and/or the export of carbon from leaves under elevated C02 partial pressure ([C02]), we raised two lines of transgenic rice (H54-9 and H69-7), each ...

Improved Efficiency of Miscible C02 Floods and Enhanced Prospects for C02 Flooding Heterogeneous Reservoirs [PDF]

open access: yes, 1998
In this quarter, we used parallel isolated composite core to test the effectiveness of foam on oil recovery efficiency. This composite core differs from the previous core in two areas: 1) Pyrex® glass beads were used in the center region to form a high permeability region and 2) a fired Berea sandstone was used in the annulus region to form a low ...
