As close relatives of land plants, green algae provide insights into variations on photosynthesis. Many algae including Chlamydomonas reinhardtii have carbon-concentrating structures called pyrenoids that enrich CO2 around Rubisco, minimizing the competing oxygenation reaction. In a recent preprint,…

Enhancing photosynthetic CO₂ fixation to increase crop yields is a major focus in plant biotechnology. Notably, several algal species form pyrenoids, phase-separated organelles that boost the activity of the CO₂-fixing enzyme Rubisco by supplying it with concentrated CO₂, thereby making carboxylation…

Many factors contribute to global hunger, but progress in many sensible directions such as lowering waste and improving distribution has been negligible; furthermore, the ever growing challenges of climate change continue to hinder food production. Photosynthesis is a critical yet inefficient process…

The United Nations projects that by 2050, global food production must increase by 60% to meet growing demand, a goal that must be met under the pressures of global climate change and without further agricultural land expansion. With rising atmospheric CO₂ levels, Rubisco has emerged as the primary…

Rubisco (Ribulose‐1,5‐bisphosphate carboxylase/oxygenase) is the central enzyme for photosynthesis, This enzyme poorly discriminates between CO2 and O2, which limits its efficiency.  To work around this and make carbon assimilation more efficient, scientists have been employing different engineering…

Photosynthesis is the process by which plants assimilate carbon by using light energy. However, with the solar energy conversion efficiency of many crop plants less than 1%, it is inefficient. Therefore, there is interest in manipulating photosynthesis for increased efficiency. Here, Croce et al. identifying…

Rubisco (ribulose-1,5-bisphosphate carboxylase) catalyzes the fixation of atmospheric carbon from CO2 to molecules used for biosynthesis and energy production. Several studies have focused on understanding the nature, complexity, activity, and regulation of Rubisco due to its key role in the production…

Rubisco is a major enzyme in assimilating CO2 during photosynthesis. The efficiency of CO2 assimilation is compromised by a low ratio of CO2/O2, especially in C3 plants like rice, wheat and soybean. Algae sequester Rubisco as a condensate in a microcompartment called a pyrenoid within the chloroplast…
