转录因子结合基序（TF Binding Motif）是转录因子结合到下游基因的一段保守DNA序列，通常为6-10bp长度，是基因转录调控的重要元件，其突变往往会改变植物基因组稳定性以及转录因子对下游基因表达调控的能力。
近日，农学院张文利课题组在 “Nucleic Acids Research”上发表了题为“The roles of DNA methylation on pH dependent i-motifs (iMs) formation in rice”的研究论文。该研究是在前期的研究基础之上（Nucleic Acids Res 2022, 50:3226-3238），再次利用iM-IP-seq方法，从全...
