Stomata play an important role in balancing the amount of CO2 that goes in the plant for photosynthesis and the amount of water that goes out of the plant through transpiration. Stomatal density (SD) in plants has been studied with the goal of improving water-use efficiency (WUE) without sacrificing photosynthetic capacity. Fan et al. studied […]
With climate change, drought is expected to happen more frequently, making supplemental irrigation increasingly necessary to sustain crop productivity. One target trait to improve climate resilience is water use efficiency (WUE), defined by the ratio of carbon assimilation to water used by the plant. However, directly measuring WUE is time consuming and low-throughput, highlighting the […]
C4 photosynthesis, an adaptive mechanism to spatially concentrate CO2 around Rubisco to enhance carbon fixation, has evolved independently at least 60 times in plants. This process spatially separates the initial carbon fixation by PEPC and carbon reduction by Rubisco, which requires that compounds move in and out of various organelles of mesophyll cells and bundle […]
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 strategies, several of which are summarized in a new review by Qin et al. One strategy is to alter […]
