Fig. 1. Sequences of ALS enzyme at sites 1860-1890 for different rice populations Z19-WT, HZ-WT, Z18-WT, and K6-WT were the control populations of Zhennuo 19, Huazhan, Zhendao 18, and Soft Rice K6, respectively. Z19-T4, HZ-47, Z18-43, and K6-1 were ALS-resistant populations of Zhennuo 19, Huazhan, Zhendao 18 and Soft Rice K6, respectively.
