Purification of a Plant Mediator from Arabidopsis thaliana.
The Mediator complex is a large, multi-subunit, transcription co-regulator that is conserved across eukaryotes. Studies of the Arabidopsis Mediator complex and its subunits have shown that it functions in nearly every aspect of plant development and fitness. In addition to revealing mechanisms of regulation of plant-specific pathways, studies of plant Mediator complexes have the potential to.
Mediator, a central coregulator of transcription, has been identified as a large protein complex in eukaryotes ranging from yeast to man. It is therefore remarkable that Mediator has not yet been identified within the plant kingdom. Here we identify Mediator in a plant, Arabidopsis thaliana.
Development of plant organs requires constant monitoring of endogenous and environmental cues for which plant cells have evolved a wide array of sensors. Among them, the receptor-like kinase (RLK) family is of particular relevance for plants due to its remarkable expansion during plant evolution. RLKs sense exogenous and endogenous signals, controlling a myriad of processes such as responses.

In Arabidopsis, leaves produced during the juvenile vegetative phase are simple, while adult leaves are morphologically complex. The juvenile to adult transition is regulated by miR156, a microRNA that promotes juvenility by impeding the function of SPL transcription factors, which specify adult leaf traits. Both leaf derived sugars, as well as the Mediator Cyclin Dependent Kinase 8 (CDK8.

Mediator is a multiprotein complex that functions as a transcriptional coactivator in all eukaryotes.It was discovered in 1990 in the lab of Roger D. Kornberg, winner of the 2006 Nobel Prize in Chemistry. Mediator complexes interact with transcription factors and RNA polymerase II.The main function of mediator complexes is to transmit signals from the transcription factors to the polymerase.
