PeGLK1-1 in moso bamboo (Phyllostachys edulis) is a principal regulator of photosynthesis, enhancing carbon fixation capacity in transgenic rice under elevated CO2 (eCO2).
- Why it matters: Elevated CO2 linked to greenhouse warming threatens ecosystem sustainability, while improving photosynthetic carbon fixation is key for climate mitigation.
- What they did: The study identified four GLK members in Phyllostachys edulis and tested PeGLK1-1 overexpression and editing of PeRbcS2 and PePRK1 in transgenic rice under eCO2.
- The result: PeGLK1-1 is positively correlated with Calvin cycle genes PeRbcS2 and PePRK1, binds 5'-AAAAA-3' to activate their transcription, and their editing decreases while transient overexpression increases photosynthetic capacity under eCO2.
