Researchers in Mexico ask the government to write clear rules for gene-edited crops. They say tools such as CRISPR-Cas change crop traits faster and more precisely than traditional breeding, so rules should be different from those for GMOs.
Twenty-eight researchers published a statement and launched a petition on Change.org. They want evidence-based regulations that allow gene editing to improve nutritional value and drought tolerance while keeping oversight and controls.
In March President Claudia Sheinbaum signed a decree that bans the cultivation of genetically modified maize. Some researchers worry the decree could be read to include gene-editing methods that do not add foreign genes. Argentina and Chile chose different rules in 2015 and 2017.
