Oryza meridionalis is a wild species of rice, endemic to tropical Australia. It shares a significant genome homology with the common domesticated rice Oryza sativa. Exploiting the fact that the two species are highly related but O. meridionalis has superior heat tolerance, experiments were undertaken to identify the impact of temperature on key events in photosynthesis. At an ambient CO2 partial pressure of 38 Pa and irradiance of 1500 μmol quanta m-2 s-1, the temperature optimum of...[Show more]
