Table 1 Differences in carboxylation efficiency (CE) and CO 2 compensation point (CP) between rice (C3) and sorghum (C4) at 21 and 2% oxygen level

From: Improvement of photosynthesis in rice (Oryza sativa L.) by inserting the C4 pathway

  CE (mol mol-1) Increase in CE when O2level was reduced from 21 to 2% CO2CP (mol mol-1)
21% O2 2% O2 (%) 21% O2 2% O2
Rice 0.123 0.174 41.5 54.877 30.241
Sorghum 0.795 0.844 6.1 0.587 0.365
