Other claims from this paper (7)
- Observation During early sugar accumulation, D1 and PsbQ protein levels in sugarcane leaves decreased significantly.
- Observation Transcript levels of D1 and PsbQ also decreased in early sugar build-up, suggesting that nuclear and chloroplast gene expression were affected.
- Observation Transcript of the carbon fixation enzyme NADP malate dehydrogenase was especially downregulated in sugarcane leaves.
- Observation PEPCase and Rubisco were not negatively regulated at the transcript or protein abundance level in sugarcane leaves.
- Observation Phosphoenolpyruvate carboxykinase was upregulated in sugarcane leaves at both gene expression and protein abundance levels.
- Observation The Calvin cycle in the bundle sheath of sugarcane leaves was sensitive through the CP12 protein.
- Observation One of two CP12 isoforms was downregulated, coinciding with a decrease in CP12 protein in sugarcane leaves.
