In a first, Japanese scientists have used the CRISPR-Cas9 genome-editing tool to change the colour of a flower in a Japanese plant. By disrupting a single gene, the colour was altered from violet to white, with a successful mutation rate of 75%. The technique cuts the two strands of DNA at certain locations, allowing DNA to be removed and/or added.
