This study reports the creation of herbicide-resistant rice lines via CRISPR-Cas9-mediated editing of the 3' UTR of OsHPPD. Resistance index calculations revealed that two resistant lines, TS8-2-10 and TS8-8-6, exhibited 4.8-fold and 3.7-fold greater resistance to HPPD-inhibiting herbicides compared with the wild type, YG3012.
本研究通过 CRISPR-Cas9 介导的 OsHPPD 3'UTR 编辑，创建了抗除草剂的水稻品系。抗性指数计算表明，与野生型 YG3012 相比，两个抗性品系 TS8-2-10 和 TS8-8-6 对 HPPD 抑制剂除草剂的抗性分别提高了 4.8 倍和 3.7 倍。
