Evolutionary Analysis of DELLA-Associated Transcriptional Networks
DELLA proteins are transcriptional regulators present in all land plants which have been shown to modulate the activity of over 100 transcription factors in Arabidopsis, involved in multiple physiological and developmental processes. It has been proposed that DELLAs transduce environmental information to pre-wired transcriptional circuits because their stability is regulated by gibberellins (GA...
متن کاملEvolutionary dynamics of prokaryotic transcriptional regulatory networks.
The structure of complex transcriptional regulatory networks has been studied extensively in certain model organisms. However, the evolutionary dynamics of these networks across organisms, which would reveal important principles of adaptive regulatory changes, are poorly understood. We use the known transcriptional regulatory network of Escherichia coli to analyse the conservation patterns of t...
متن کاملEvolutionary and Temporal Dynamics of Transcriptional Regulatory Networks
Transcriptional regulation is a key mechanism that allows cells to make the appropriate amount of proteins at the right time. This is mediated by transcription factors that respond to specific signals and regulate expression of the relevant genes. The set of all regulatory interactions in a cell can now be investigated and this is best represented as the transcriptional network where nodes repr...
متن کاملAnalysis of Biological Networks: Transcriptional Networks - Promoter Sequence Analysis
Each cell of an organism contains an identical copy of the whole genome. However, different tissues have different functions, which means that each cell utilizes only a subset of its genes. The process in which the cell controls the activation of a subset of genes is called gene regulation. Gene regulation can occur at different time points along the gene expression process, including chromatin...
متن کاملGenome Wide Binding Site Analysis Reveals Transcriptional Coactivation of Cytokinin-Responsive Genes by DELLA Proteins
The ability of plants to provide a plastic response to environmental cues relies on the connectivity between signaling pathways. DELLA proteins act as hubs that relay environmental information to the multiple transcriptional circuits that control growth and development through physical interaction with transcription factors from different families. We have analyzed the presence of one DELLA pro...
