library_construction_protocol: gDNA was extracted from maize B73 14 DAG leaf. gDNA libraries was prepared using TIANSeq DirectFast Library Kit (illumina) (cat. no. NG101, TIANGEN) according to the manufacturer's instructions. gDNA libraries was prepared using TIANSeq DirectFast Library Kit (illumina) (cat. no. NG101, TIANGEN) according to the manufacturer's instructions. Full length maize transcription factors' coding sequences were cloned from maize 14 DAG leaf cDNA into the NotI and AscI sites of pUC57-Halo using MultlF Seamless Assembly Mix (cat. no. RM20523, ABclonal). Protein expression was using TNT SP6 High-YIELD Wheat Germ Master Protein Expression System (cat. no. L3260; Promega) according to the manufacturer's instructions. Halo-fusion protein was bound to Magne HaloTag Beads (cat. no. G7281; Promega) and washed three times using TBSN buffer( 100 mM Tris buffer, pH 7.5, 50 mM NaCl, 0.005 % NP40). Then, 500 ng gDNA libraries was added and incubated at room temperature for 1.5 h. After incubation the beads was washed four times. Resuspended the beads in 30µl of EB buffer to recover DNA. The recovered DNA was were cleaned up with Silane magnetic beads, and amplified via PCR. The PCR products were cleaned up with Silane magnetic beads and sequenced using an NovaSeq platform (Illumina) by BerryGnomics.
