Charting plant hormone signaling pathway networks using ChIP-Seq: Aimed at deciphering the interaction between auxin and cytokinin, based on studies in the Ecker lab, the core cytokinin transcriptional regulatory network and discovery of the auxin transcriptional responses: auxin code hypothesis. Also adapting the INTACT method into a simpler version-INTACTone in order to study transcriptional network, transcriptome, epigenetic landscapes, and so on at cell type-specific resolution. Ultimate aim to improve plants of economic importance by application of our understanding of the mechanisms of plant hormone actions.
