| Research Abstract |
Residues for functional improvement of RuBisCO were identified by the results form studies of thermophilic cyanobacterial RuBisCO and RuBisCO ancestral protein from Bacillus. I found a pre-Calvin cycle for CO_2 fixation using RuBisCO in methanogenic archaeon. Improvement of plant RuBisCO by replacement with red-algal residue enabled to perform a normal photosynthetic CO_2-fixing with low RuBisCO level in tobacco. The genes necessary for the achievement of RuBisCO accumulation were identified for quantitative enhancement of RuBisCO to increase photosynthetic capacity.
