**cloning**
- cloning of transformation vectors was performed according to the protocol by Kumar et al. (2018)
- sgRNAs were cloned into recipient vector pMGE599
- two sgRNA combinations:
| approach | covered CDS sequence (from start codon) | sgRNA sequence (incl. PAM, 5'-3') | construct name |
| - | - | - | - |
| 1 | 7-26, 97-116 | GGCGGTGGCGCAGCCGCGGATGG, GAGATCTATACCTACGAGGCCGG | pMGE599/7-97
| 2 | 1182-1201, 1222-1241 | GGTCAGCTACCCAGCCTGACTGG, TAATAAACTGCAGATTCTCA GGG | pMGE599/182-1222
**transformation**
- gp-fast plants were cultivated in long-day conditions (16h day / 8 night) in control temperature (20°C / 16°C)
- immature embryos were used for transformation according to Hensel et al. (2009)
- DNA was extracted from regenerated plants using QIAGEN_DNeasy-Plant-Mini protocol
- successful insertion of the transformation vector into the genome was tested by PCR using the primers Hyg-156 (5'-ACGCACAATCCCACTATCC-3') and Hyg-047 (5'-GTGTCGTCCATCACAGTTTG-3')
