| Research Abstract |
1: We showed that the low atmospheric pressure, low internal condunctance for CO_2, and large amount of activated Rubisco cause drop in an optimum temperature for leaf photosynthesis using the simulation analysis. 2: We didn't detect any difference of CO_2/O_2 specificity of Rubisco between a low temperature population grwoing at a high altitude and a high temperature population growing at a low altitude. 3: The low temperature poulation showed the optimum temperature for leaf photosynthesis as low as 5℃ than the high temperature population. We showed this adaptation was mainly caused by the differences in the amount of activated Rubisco at high temperature. 4: There was not significant diffference in the internal conductance, which increased at high temperature, beteen the populations.
