Special Issue Information
Dear Colleagues,
The open access journal Plants is now accepting submissions for a Special Issue on "Elongator and Its Role in Plant Development and Response". This Special Issue will include reviews (except mini-reviews) and original research articles including short communications written by experts in the field. Accepted papers will be published online shortly after copy editing.
The elongator protein complex regulates development and response mechanisms in yeast, animals and plants. Although ubiquitous and highly conserved in structure, elongator controls diverse pathways in the kingdom-specific way, while its catalytic activities and molecular functions are controversial and seem to differ between organisms. Elongator was identified as a histone acetyltransferase positively regulating transcription elongation, but this role of the complex has been recently challenged. In plants, elongator was implicated in particularly diverse processes and activities both in cell nucleus (regulation of mRNA transcription, miRNA transcription and processing, DNA replication, DNA (de)methylation) and in cytoplasm (tRNA modification and acetylation of alpha-tubulin). It remains elusive how exactly the individual activities of elongator contribute and converge to regulate plant development and response. Strong experimental evidence indicates that in all kingdoms elongator works as a complex, while the recent studies suggest that the individual Arabidopsis subunits expressed in the heterologous systems may be functional. Finally, the vast majority of plant elongator research is focused on the model plant Arabidopsis thaliana, leaving the role played by the complex in the other plant species largely unexplored.
The aim of the Special Issue is to present the results of the studies addressing important questions related to plant elongator:
- Which aspects of plant development and response are regulated by the elongator complex?
- Via which catalytic activities and/or molecular processes does elongator accomplish this regulation?
- Does elongator always work as the six subunit complex? May individual subunits or subcomplexes (core or accessory subcomplex) act independently?
- What are the roles of elongator in plant species other than Arabidopsis thaliana?
