The photosynthesis fix

As world food needs rise, so does the need for faster, more efficient plant growth. Bypassing an error-prone enzyme is one way to do it.

Light green plants save nitrogen without sacrificing photosynthetic efficiency

Scientists designed plants with light green leaves with hopes of allowing more light to penetrate the crop canopy and increase overall light use efficiency and yield. This strategy was tested in a recent modeling study that found leaves with reduced chlorophyll content do not actually improve canopy-level photosynthesis, but instead, conserve a significant amount of nitrogen that the plant might be able to reinvest to improve light use efficiency and increase yield.
