Special Issue "Role of Bacterial Chromatin in Environmental Sensing, Adaptation and Evolution"
Deadline for manuscript submissions: closed (31 October 2019) | Viewed by 30581
Bacterial genomes are organized and compacted into a structure called the ‘nucleoid’ by a multitude of factors that include architectural proteins, DNA topology and macromolecular crowding. Due to interplay between genome organization and DNA transactions, these factors play specific and generic roles in processes such as transcription, replication, repair and chromosome segregation. Environmental signals that alter genome organization thus drive adaptive responses to changes in the environment. It has become clear that the genomic incorporation and maintenance of foreign DNA is facilitated by factors involved in silencing the expression of foreign DNA (xenogeneic silencing) until relieved by specific signals. In this light, the spatio-temporal organization of the genome is currently a topic of great interest, explored at both the cellular and molecular levels. At the same time, over the last years there has been increasing interest in genome organization in non-canonical model organisms, providing comparative perspectives, demonstrating unanticipated activities of proteins involved in shaping the nucleoid of these organisms and revealing novel architectural proteins. In this Special Issue of Microorganisms, we invite contributions concerning any aspect of bacterial genome organization, with a particular emphasis on the interplay between genome organization and DNA transactions, xenogeneic silencing and environmental sensing in model and non-model bacterial species.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
