The lab will gather the gene editing advantages of the CAAS, develop a gene editing system with China's independent intellectual property rights, cultivate new crop varieties, and build a new industrial chain. It will also improve the original innovation ability of the biological seed industry and provide a solid guarantee for the national seed industry and food security, the CAAS said.
