India has become the first country in the world to develop genome-edited rice varieties. The Indian Council of Agricultural Research (ICAR) has developed two such varieties named DRR Rice 100 (Kamla) and Pusa DST Rice. These rice varieties were developed using genome editing technology based on Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR Associated Protein (CRISPR-Cas). This technology allows precise changes in the genetic material without adding any foreign DNA. Genome editing targeted the Site Directed Nuclease 1 (SDN1) and SDN2 types of genes, which are approved under India’s biosafety rules. The development was supported by the National Agricultural Science Fund (NASF), which funds strategic agricultural research.
