Dynamic reprogramming of transcriptional networks enables cells to adapt to a changing environment. Thus, it is crucial not only to understand what gene targets are regulated by a transcription factor (TF) but also when. This review explores the way TFs function with respect to time, paying particular attention to discoveries made in plants - where coordinated, genome-wide responses to environmental change is crucial to the survival of these sessile organisms. We investigate the molecular mechanisms that mediate transient TF-DNA binding, and assess how these rapid and dynamic interactions translate to long-term temporal regulation of genomes. We also discuss how current molecular techniques can catch, and sometimes miss, transient TF-target interactions that underlie dynamic cellular responses. Tracking genome-wide dynamic transcription over time. (A–B) Closed chromatin can be rendered accessible through pioneer TF binding. (C) Post translational modification of histones via histone methyltransferases (HMTs) can earmark loci for transcriptional activation. In the hit-and-run transcriptional model, a TF can first assist with localizing HMTs to target sites, and as well as (D) activate transcription. Once a loci has been 'hit', the hit-and-run complex can move on to activate other sites (E) while transcriptional output is maintained by a secondary TF (TF2). (F) Complex molecular dynamics can be monitored genome-wide over time by combining different genomic techniques.
