Scientists tweak photosynthesis to increase crop yield

Scientists have successfully tweaked the process of photosynthesis to make it more efficient and increase plant productivity by raising the level of three proteins involved in the process.
●    Many years of computational analysis and laboratory and field experiments led to the selection of the proteins targeted in the study. 
●    Researchers used tobacco plants as it can be easily modified.
●    The researchers targeted a process plants use to shield themselves from excessive solar energy.
●    Plants protect themselves by making changes within the leaf that dissipate the excess energy as heat. 
●    This process is called non-photochemical quenching (NPQ).
●    Researchers used a supercomputer to predict how much the slow recovery from NPQ reduces crop productivity over the course of a day.
●    Researchers suggested that boosting levels of three proteins might speed up the recovery process.
●    The researchers grew seedlings from multiple experiments, then tested how quickly the engineered plants responded to changes in available light.
