Synthetic biology approaches for improving photosynthesis
摘要： The phenomenal increase in agricultural yields that we have witnessed in the last century has slowed down as we approach the limits of selective breeding and optimization of cultivation techniques. To support the yield increase required to feed an ever growing population, we will have to identify new ways to boost the efficiency by which plants convert light into biomass. This challenge could be potentially tackled using state-of-the-art synthetic biology techniques to rewrite plant carbon fixation. In this review, we use recent studies to discuss and demonstrate different approaches for enhancing carbon fixation, including engineering Rubisco for higher activity, specificity, and activation; changing the expression level of enzymes within the Calvin Cycle to avoid kinetic bottlenecks; introducing carbon concentrating mechanisms such as inorganic carbon transporters, carboxysomes, and C4 metabolism; and rewiring photorespiration towards more energetically efficient routes or pathways that do not release CO2. We conclude by noting the importance of prioritizing and combining different approaches towards continuous and sustainable increase of plant productivities.

Analysis of physical interaction between peroxisomes and chloroplast induced by dynamic morphological changes of peroxisomes using femtosecond laser impulsive force
摘要： Plant organelles dynamically change their morphology responding to environmental signals. To investigate the correlation between the light-dependent morphological changes of peroxisomes and interaction force between peroxisomes and chloroplasts, we applied femtosecond laser to estimate the interaction force between peroxisomes and chloroplasts. Here, we introduce our studies based on resent researches about organelles interaction.
