The differential expansion of regulator families in the fungal phyla and sub-phyla suggests that evolution of many regulators occurred after the divergence of these groups.
Stolt, C.C. & Wegner, M. Schwann cells and their transcriptional network: evolution of key regulators of peripheral myelination.
Evidence for fusion events in the evolution of MerR regulators has previously been outlined [18], [31].
The above limitations are widespread and would ultimately prevent a thorough investigation of the origin and evolution of key regulators of development that may have shaped the evolution of angiosperms using different pathways such as sub or neo-functionalization [37].
The independent evolution of RNA regulators is especially apparent in bacteria due to the large number of sequenced genomes, and the breadth of biological diversity these genomes represent.
In both bacteria, gene duplication events seem to have taken place which resulted in the evolution of dedicated regulators for the control of sulphonate utilisation.
Although much has been written about the evolution of transcription regulators, there has been comparatively little work on the evolutionary patterns and processes of kinases and phosophoregulatory networks.
As a member of the subphylum Urochordata (Tunicata) whose larval form has a notochord, the sea squirt is situated at the emergence of vertebrates, and therefore may provide information about the evolution of molecular regulators of early development.
We assessed the relative contribution of within- and whole- gene transfer to the evolution of individual regulators and their target genes as a necessary step toward understanding how lateral genes connect into TRNs and contribute to overall TRN evolution.
The abundance of fur genes in Actinobacteria and their phylogenetic relationship points towards early duplications in the evolution of these regulators, along with additional HGT and later intra-species duplications.
