Eucalyptus trees can be modified to prevent invasive spreading

Eucalyptus trees can be genetically modified to prevent them from reproducing and invading native ecosystems, according to a study from Oregon State University.  The advanced gene editing technique used by the researchers was nearly 100 percent efficient in knocking out the master gene behind flower formation, known as LEAFY. "The flowers never developed to the point where ovules, pollen or fertile seeds were observed," said Professor Steven Strauss. "And there was no detectable negative effect on tree growth or form."  "A field study should be the next step …
