Summary: Excessive accumulation of Mn in rice plants inhibits CO2 assimilation, carbon anabolic and catabolic activities, and alters stomatal and leaf anatomical development. The deficiency of IAA caused by excessive Mn accumulation suppresses plant growth by inhibiting stomatal opening and leaf anatomical development for efficient CO2 assimilation in leaves.

Summary: The CO2-fixing enzyme rubisco is responsible for almost all carbon fixation. Rubisco activase (Rca) machinery is often required for this process. However, characterized carboxysomal rubiscos are not prone to inhibition and do not require activase machinery. New research has identified two carboxysomal rubiscos that release the substrate RuBP at a slower rate. It has also been found that activases encoded in carboxysome gene clusters can remove RuBP from the corresponding rubiscos. These findings have implications for improving carbon fixation in crops and introducing biophysical CCMs into plants and other hosts.

Summary: RuBisCO is the carbon-fixing enzyme in most photosynthetic organisms, with the C4 pathway utilizing carbon concentrating mechanisms to increase CO2 levels, while the energy efficiency of C3 photosynthesis relies on chloroplast CO2 supply. RuBisCO possesses extensive kinetic plasticity for adaptation to changes in photorespiration under various environmental conditions.

Summary: This review discusses the processes and variations related to dynamic photosynthesis in crop plants under field environments. The study reveals that plant adaptations to different hydrological environments are explained by natural genetic variation in gas diffusion through stomata. The coordination of photosynthetic and stomatal dynamics is emphasized for optimizing the balance between carbon gain and water use efficiency. Future challenges include utilizing natural genetic variation and employing high-throughput phenotyping to evaluate the effects of genetic and environmental factors on dynamic photosynthesis.

Summary: Researchers have successfully replaced plant Rubisco with a faster Rubisco in tobacco chloroplasts, resulting in a higher carboxylation rate and similar growth rate of transgenic plants compared to the wild-type under 1% CO2 concentration. This study represents a step towards engineering a fast and highly active Rubisco in chloroplasts to improve crop photosynthesis and growth.

Summary: Rubisco is a crucial enzyme present in all photosynthetic organisms, and this study elucidates the biogenesis pathway of Rubisco in Chlamydomonas reinhardtii using site-directed mutants. The research uncovers a major regulation process during Rubisco biogenesis, where LSU translation is controlled by its ability to assemble with SSU, and proposes a model where the LSU8-RAF1 complex acts as a platform for SSU binding.

Summary: In this study, it was found that the activity of Rubisco, the major catalyst in carbon dioxide conversion, is impaired by inhibitory sugars. The loss of two phosphatases in plants negatively affects plant growth and photosynthesis, but this effect can be reversed by introducing a XuBP phosphatase from Rhodobacter sphaeroides. This finding demonstrates the physiological importance of a metabolite damage-repair system in degradation of Rubisco by-products and has implications for carbon fixation optimization in photosynthetic organisms.

Summary: This study used eight genotypes of canola with varying leaf nitrogen content to investigate the effects of leaf nitrogen content on non-steady-state photosynthesis under dynamic light conditions. Significant differences in physiological characteristics and photosynthetic traits were observed among genotypes, with higher leaf nitrogen content genotypes showing a faster induction of photosynthesis to fluctuating light conditions.

Summary: This study developed a mixotrophic CO2-fixing Saccharomyces cerevisiae by constructing a CO2-fixation pathway and increasing the gene copy number of ribulose-1,5-bisphosphate carboxylase-oxygenase. The resulting yeast strain exhibited increased ethanol concentration and yield and reduced CO2 emissions during xylose fermentation.

Summary: Increasing leaf nitrogen content may not offset the reduction in photosynthetic acclimation under high CO2 concentrations and elevated temperatures in rice. The effects of elevated CO2 and air temperature on chlorophyll and carotenoid content were similar to the changes in total leaf nitrogen content.
