Improving Rubisco
Plant Science Research Weekly, Research0 Comments
/
Rubisco (Ribulose-1,5-bisphosphate carboxylase / oxygenase) is the enzyme responsible for fixing almost all inorganic carbon into organic form, but it is not optimized for current conditions. As temperature and CO2 levels increase, there is an opportunity to increase photosynthetic efficiency by engineering…
Transcript, protein and metabolite dynamics in CAM-plant Agave ($)
Plant Science Research Weekly, Research
Crassulacean acid metabolism (CAM) is a specialized form of photosynthesis that greatly increases water-use efficiency by taking up CO2 through stomata that are open at night (when evapotranspiration is low). Engineering plants that can switch to CAM during periods of drought is a key goal towards…
Commentary: Chemical nature of the root-shoot signals
Plant Science Research Weekly, Research
Unravelling the mechanism and signals originating from roots and able to contribute to stomatal control has been the subject of research for decades. In this commentary, Tardieu summarizes and discusses many studies and models on root-shoot signals, including work in the same issue by Visentin et…
Metabolic Signaling Regulates Alternative Splicing during Photomorphogenesis
Research, The Plant Cell, The Plant Cell: In BriefIN BRIEF by Kathleen L. Farquharson [email protected]
Alternative splicing (AS) regulates gene expression and greatly expands the coding capacity of complex genomes. By regulating which elements of an mRNA transcript are removed or retained, AS produces multiple transcripts from a single gene. Some…
