Arabidopsis genomic DNA
Methods:
1.add material into a 0.2ml EP tube according to the table
| Material | dosage/μl |
|---|---|
| dNTPs mix | 1 |
| Forward primer | 0.5 |
| Reverse primer | 0.5 |
| Arabidopsis genomic DNA | 3 |

| Taq polymerase | 0.5 |
| Total | 20 |
2.set the PCR program
For promoter cop1,phyB,pif1,gene hhl1,gene flu:
94℃ × 5min +(94℃×30s +Tm×30s +72℃×1min)×35+72℃×5min +4℃(for preserving)
For pHhl1-gene hhl1:
94℃ × 5min +(94℃×30s +Tm ×30s +72℃×90s) ×30+72℃×5min +4℃(for preserving)
Tm of each primer: (view primer sequence in PDF)
| Name | Tm(Forward/Reverse)(℃) | Tm in PCR(℃) |
|---|---|---|
| Promoter pif1 | 62.59/62.67 | 63 |
| Promoter cop1 | 66.77/65.46 | 66 |
| Promoter phyB | 63.94/63.90 | 64 |
| pHhl1-genehhl1 | 60.75/59.38 | 60 |
| gene hhl1 | 60.90/59.38 | 60 |
| Fluorescent gene flu | 62.42/66.90 | 65 |
