Identification of LEC1 binding sites in Arabidopsis seeds during embryo expansion stage
Ontology highlight
ABSTRACT: LEAFY COTYLEDON1 (LEC1), a subunit of the NF-Y CCAAT binding transcription factor, is a key regulator that controls many aspects of seed development including embryo growth and seed storage accumulation. To identified genomic region bound by LEC1 and target genes of LEC1, we expressed a FLAG-tagged form of LEC1 under the control of its native promoter and terminator in lec1-4 mutant seeds. Using an anti-FLAG antibody (Sigma), we performed chromatin immunoprecipitation followed by sequencing (ChIP-Seq) using chromatin isolated from mature stage seeds to identify the genes bound by LEC1. These data reveal that the transcription regulation network of LEC1.
