| Characteristics |
dap antibody: Halo
antibody manufacturer: Promega
antibody catalog #: G7281
cultivar: Chinese Spring

| Growth protocol |
16h light, 8h dark, 22°C

| Extracted molecule |
genomic DNA |
| Extraction protocol |
Genomic DNA was extracted from leaves using Plant DNAzol Reagent(invitrogen). RNA was extracted using TRIzol.
Genomic DNA was fragmented. And then end repaired using the End-It kit(Lucigen) and A-tailed using Klenow(3′–5′ exo-; NEB). Truncated Illumina Y-adapter was ligated to DNA using T4 DNA Ligase(Promega). Full length TF was cloned into pIX-Halo vector. Halo-tagged TF was expressed in vitro using TNT SP6 Coupled Wheat Germ Extract System(Promega). Halo-TF was immobilized by Magne HaloTag Beads(Promega) and then incubated with the DNA library. TF specific binding DNA was eluted for 10 min at 98°C and amplified with indexed Illumina primer using Phanta Max Super-Fidelity DNA Polymerase(Vazyme). Meanwhile, to capture background DNA which captured by Halo, pIX-Halo vector without TF cloned was expressed and incubated with the DNA library as well. The PCR product was purified using VAHTS DNA Clean Beads(Vazyme).

| Data processing |
Sequencing reads were cleaned with the fastp(version 0.20.0) and Trim Galore (version 0.4.4), which eliminated bases with low quality scores(< 25) and irregular GC contents, sequencing adapters, and short reads.
The remaining clean reads were mapped to the Chinese Spring (T. aestivum) genome with the Burrows–Wheeler Aligner(version 0.7.17-r1188).
The MACS(version 2.2.6) program was used to identify the read-enriched regions(peaks) based on the criteria: P < 1e−10. The peaks detected from samples introduced with Halo tag only were considered as non-specific bindings, and TF peaks overlapping with peaks detected from Halo samples were removed for subsequent analysis.
