| Research Abstract |
Pyruvate is an essential metabolite for multiple plastid-localized metabolic pathways of plants, including the C4 photosynthetic CO, -concentrating mechanism. Despite the crucial role of pyruvate import into plastids, the molecule mediating pyruvate transport is still unknown. Using differential transcriptome analyses of the C3 and C4 plants of the genus Flaveria, we have identified a novel plastid-localized transporter gene, named BASS2, for bile acid : sodium symporter family protein 2, the transcript of which is abundant in C4 plants that have the sodium-dependent pyruvate transporter. Recombinant BASS2 shows sodium-dependent pyruvate uptake activity.
