Inorganic carbon acquisition is an essential step in driving a biophysical CCM and for maximizing its efficiency. Acquisition of the predominant Ci species (CO2 and HCO3−) contributes to the accumulation of an intracellular/chloroplastic HCO3− pool well above external Ci levels, with up to 1,000-fold increases observed … See more Crop improvement technologies utilizing synthetic biology approaches have been central to a number of recent advances in photosynthetic output (e.g., Kromdijk et al., 2016; Salesse-Smith et al., 2024; Ermakova et al., … See more The terrestrial nature of C3 plants and their appearance in geological history during a period of relatively high atmospheric CO2 … See more The expression of transgenes from the nuclear genome of terrestrial plants is the favored means to introduce a CCM into crop plants due to … See more One major challenge for heterologous expression of Ci uptake systems is the regulation of protein function, which encompasses both primary energization and fine-tuning of … See more WebSep 3, 2024 · An engineering strategy to generate a chloroplastic CCM in crop plants (Fig. 1b) relies on transfer of genes encoding HCO 3− transporters, directed to the …

WebNov 29, 2013 · Here, the “chloroplast pump” model of the CCM in P. tricornutum is formalized and its consistency with data on CO2 and HCO3 − uptake rates, … WebThis strategy recognises the C3 chloroplast as lacking a CCM, and being a primordial cyanobacterium at its essence. Hence the collection of solute transporters, enzymes, and physical structures that make cyanobacterial CO2-fixation so efficient are viewed as a natural source of genetic material for C3 chloroplast improvement. the shrubbery veterinary centre

WebAbstract. The carbon-concentrating mechanism (CCM) is essential to support photosynthesis under CO2-limiting conditions in aquatic photosynthetic organisms, … WebHere, a CO2 and HCO3 − diffusion-reaction model is developed to examine how components of the cyanobacterial CCM affect leaf light-saturated CO2 uptake (A sat) and to determine whether a different Rubisco isoform would perform better in a leaf with a cyanobacterial CCM. The results show that the addition of carboxysomes without other … WebOct 11, 2024 · Strikingly, the abundance of many proteins outside of the chloroplast was altered in the deg1c mutant when compared with the wild type. Among these proteins were several components of the carbon dioxide concentrating mechanism (CCM), like periplasmic CAH1 and mitochondrial CAH4, which were strongly upregulated in the deg1c mutant. … my thumbkin patch
