Modified Genes Triggered by Blue Light

Crossing a bacterium’s viral defense system with a flower’s response to the sun yields a light-based trigger for genes. This type of control could enable deeper study of specific genes’ functions, create complex systems for growing tissue and perhaps healing technologies, according to researchers at Duke University. “This technology should allow a scientist to pick any gene on any chromosome and turn it on or off with light, which has the potential to transform what can be done with genetic engineering” said doctoral student Lauren Polstein. ...Read full article
