Researchers from the UK and Poland found that engineering phototropins in the model organism Arabidopsis thaliana led to an increase in light sensitivity, as they report in the Proceedings of the National Academy of Sciences this week. Using target mutagenesis in vitro, they altered the photocycle lifetime of the phototropins phot1 and phot2, which are activated by blue light and are involved in photosynthetic efficiency.
