"PeerJ Preprints" is a venue for early communication or feedback before peer review. Data may be preliminary.

Supplemental Information

Prime names and sequences

The primers of NAC13 are used to amplify the coding sequence of NAC13 gene. NAC13F1 and NAC13R1 are used to clone the ORF sequence of NAC13 gene; NAC13F2 and NAC13R2 are used to generate the recombinant construct 35S::NAC13-GFP, and the underlined area is the restriction site Spe I; NAC13F3 and NAC13R3, NAC13aF and NAC13aR, NAC13bF and NAC13bR are used to generate bait vector pGBKT7-NAC13, pGBKT7-NAC13a and pGBKT7-NAC13b, respectively. The underlined areas are EcoR I and Sal I restriction sites; NAC13F4 and NAC13R4 are used to amplify the complete cDNA sequence of NAC13 gene and introduce into the plant binary vector pBI121. The underlined areas are restriction sites Xba I and Sac I.
