Japanese scientists use gene editing to develop melons with longer post-harvest shelf lives

Researchers at the University of Tsukuba in Japan used CRISPR/Cas9 gene editing technology to develop a variety of melon that has a longer shelf life (14 more days). This technology could reduce food waste and contribute to global food security. The journal Frontiers in Genome Editing published a study of international interest that could help reduce food waste. The study authors used biotechnological gene editing tools to extend the shelf life of a variety of Japanese melon. The genetically edited melon is capable of maintaining its green skin and firm pulp for up to 14 days after harvest. The gene editing technology applied was the CRISPR/cas9 system, known for its precision and effectiveness in plant improvement. Scientists inactivated the function of a single gene (cmACO1) involved in the production of ethylene, a hormone related to fruit ripening. This discovery could have a significant global impact if the process is ...
