Florida citrus growers are planting gene-edited trees designed to resist citrus greening disease, which has devastated the state's industry since 2005. Soilcea used CRISPR technology to create the CarriCea T1 rootstock, which keeps trees' immune systems functioning against the bacterial infection spread by Asian citrus psyllids. Early test results are promising, though growers await years of data to confirm the modification's long-term effectiveness.
