Mechanism of Light Regulation of Rubisco by Rubisco Activase via Thioredoxin -F in Arabidopsis Thaliana
Rubisco activase is a nuclear-encoded chloroplast protein that is required for the light activation of ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) in vivo. In most plants examined to date, there are two soforms of Rubisco activase arising from alternative splicing that differ only at …

Improving the thermal tolerance of photosynthesis in wheat
… due to a decrease in the activation state of Rubisco. Rubisco activase (Rca) is required to restore and maintain the catalytic activity of Rubisco. Rca has a relatively low temperature optimum; improving its thermal tolerance would maintain Rubisco activity and enhance photosynthesis at higher …

Transgenic approaches to improve photosynthesis and nitrogen use in wheat
… transgenic wheat plants with increased SBPase activity showed an improved photosynthetic leaf rate and total biomass production. The Rubisco protein is a major N investment in crops, but it has also been exhibited that under some environmental conditions, there may be an excess of Rubisco …

Plastidial carbonic anhydrase in cotton (Gossypium hirsutum L.): characterization, expression, and role in lipid biosynthesis
… of relative CA transcript abundance and enzyme activity in different cotton organs revealed that there was substantial CA expression in cotyledons of seedlings and embryos, both nonphotosynthetic tissues. To gain insight into the role(s) of CA, I examined CA expression in cotyledons of seedlings …

Control of Substrate Supply to the Chloroplast 2-C-methyl-D-erythritol-4-phosphate Pathway
… (ED) pathway, and a largely overlooked, minor activity of Rubisco, nature’s central carbon fixing enzyme. In this thesis, I demonstrate that Rubisco is in fact the primary source of pyruvate in illuminated chloroplasts. To do so, I employed a combination of biochemical, bioinformatic, …

Analysis of anther-derived plants of Solanum phureja: variation in ploidy, photosynthetic efficiency and structure of the nuclear genome
… increasing ploidy' Among .the. monoploids I. Rubisco activity and concentration displayed a. significant genotypic effect; whereas in the diploid group variation among genotypes was significant for total protein content and maximum specific activity of ribulose bisphosphate carboxylase. Among …

Physiological and molecular determinants of the Chlamydomonas reinhardtii pyrenoid
… Ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO). Many eukaryotic algae, and a single group of land plants, the hornworts, have an inducible carbon concentrating mechanism (CCM), to overcome these limitations. The efficiency of the CCM is improved when RuBisCO is localised to a …
