| Research Abstract |
In the CO2-concentration mechanism, performed at several C4 plants, there are a little information on the metabolic transporters located at chlloroplasts. During the identification of a pyruvate transporter, BASS2, located at mesophyl cell plastids, we also found an alternative transporter gene, BASS4, which was highly expressed at C4 Flaveria species in comparison with at C3 Flaveria. To identify the physiological importance, we tried to make transgenic Flaveria, in which Bass4 gene is knocked down. These Bass4-KD plants showed growth defect under the ambient CO2 condition and this difection was complemented under the high CO2 condition, indicates its significant function in the CO2-concentration mechanism.
