Outline of Final Research Achievements

We established yeast screening system to identify CO2 permeable aquaporins. Among 69 aquaporins from rice, barley and Arabidopsis, 18 aquaporins were identified as putative CO2 permeable aquaporins. One of these aquaporins, OsTIP2;2 was detected around chloroplasts and some organelles (possible mitochondria), and seemed to have a function to supply CO2 intracellularly to inner chloroplast.
