The P1 Transcription Factor Binding to the Genome

ABSTRACT: To determine which of the genes differentially expressed between P1-rr and P1-ww pericarps were immediate (direct) targets of P1, we conducted chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-Seq) using P1 polyclonal antibodies (alphaP1344) that recognize the non-conserved C-terminal region of P1 (Falcone Ferreyra et al., 2010), on pericarp chromatin. Comparison of pericarp chromatin inmunoprecipitated material P-rr_14DAP (P1 expressed) vs P-ww_14DAP (P1 not expressed) to determine P1 direct targets

Pericarp Color1 (P1) encodes an R2R3-MYB transcription factor responsible for the accumulation of insecticidal flavones in maize (Zea mays) silks and red phlobaphene pigments in pericarps and other floral tissues, which makes P1 an important visual marker. Using genome-wide expression analyses (RNA sequencing) in pericarps and silks of plants with contrasting P1 alleles combined with chromatin immunoprecipitation coupled with high-throughput sequencing, we show here that the regulatory functions  ...[more]
