Abstract
The photosynthetic properties, yield character of PEPC transgenic rice inoculated nitrogen-fixing bacteria and nitrogen-fixing capacity of nitrogen-fixing bacteria inoculated in PEPC transgenic rice were studied by using l5 N-isotope tracer technique. The results showed that the PEPC activity, PS Ⅱ photochemical efficiency and net photosynthetic rate of PEPC transgenic rice inoculated nitrogen-fixing bacteria increased significantly under high light intensity . The dry matter of plant and grain yield of PEPC transgenic rice increased 38.08% and 26.86% under it was inoculated with nitrogen-fixing bacteria. Compared with no PEPC gene rice, the PEPC transgenic rice could enhance nitrogen-fixing capacity of nitrogen-fixing bacteria. The mechanism of acceleration between photosynthesis of PEPC transgenic rice and nitrogen fixation of nitrogen-fixing bacteria in PEPC transgenic rice need to be studied deep.
