Synthetic biology approaches to improve Rubisco carboxylation efficiency in C Plants: Direct and Indirect Strategies.

Food security remains a pressing issue due to the growing global population and climate change, including the global warming along with increased atmospheric CO levels, which can negatively impact C crop yields. A major limitation in C plants is the inefficiency of Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) due to its low carboxylation activity and competing oxygenase activity. Improving Rubisco efficiency in C plants is thus essential for improving photosynthetic performance.

Crucial role of SWL1 in chloroplast biogenesis and development in Arabidopsis thaliana.

The disruption of the SWL1 gene leads to a significant down regulation of chloroplast and secondary metabolites gene expression in Arabidopsis thaliana. And finally results in a dysfunction of chloroplast and plant growth. Although the development of the chloroplast has been a consistent focus of research, the corresponding regulatory mechanisms remain unidentified.

Dissolved oxygen disturbs nitrate transformation by modifying microbial community, co-occurrence networks, and functional genes during aerobic-anoxic transition.

No consensus has been achieved among researchers on the effect of dissolved oxygen (DO) on nitrate (NO-N) transformation and the microbial community, especially during aerobic-anoxic transition. To supplement this knowledge, NO-N transformation, microbial communities, co-occurrence networks, and functional genes were investigated during aerobic-anoxic transition via microcosm simulation. NO-N transformation rate in the early stage (DO ≥2 mg/L) was always significantly higher than that in the later stage (DO <2 mg/L) during aerobic-anoxic transition, and NO-N accumulation was more significant during the anoxic stage, consistent with the result obtained under constant DO conditions.
