Table 2. Summary of the transformation experiments, number of transgenic plants, and mutations of TaQsd1.
| Heat treatment | sgRNA promoter | Number of experiments | Number of embryos | Transgenic plants (number, rate)* | Genome-edited plants (number, rate) | Mutant genotype** and plant line number |
|---|---|---|---|---|---|---|
| “25°C” (25°C, 5 day) | OsU6 | 8 | 567 | 12, 2.12% | 0, 0% | |
| TaU6 | 8 | 586 | 13, 2.22% | 5, 0.85% | AABBDd, T7 AABbDD, T18 AaBbDd, T19 aabbdd, T12, T26 | |
| “30-1d” (30°C, 1 day) | OsU6 | 8 | 603 | 14, 2.32% | 1, 0.17% | AABbDD, O20 |
| TaU6 | 8 | 585 | 13, 2.22% | 6, 1.03% | AABbDd, T15 AaBbdd, T2 aabbdd, T10, T16, T23, T24 |
*The rate was calculated based on the number of regenerated PCR-positive transformants per callus piece. Only one regenerated plant per callus piece was retained. The Cas9 or bar DNA fragment was detected by PCR. **TaQsd1 genotype.
