Transposable elements (TEs) are mobile DNA sequences that are able to change their chromosomal location. These sequences, which are present in the nuclear genomes of all eukaryotes, were first isolated in consequence of the polymorphisms they induced in hosts. The huge abundance of TEs in plant genomes necessarily results in their interaction with genes over long evolutionary scales. The mutagenic action of TEs creates substantial genetic variability. The proliferation of TEs introduces novel functions via fine-tuning gene activity, contributing, through epigenetic regulation, to the organization of the genome or, after the elements become transcriptionally inactive, introducing a structural variation in insertion sites. Transposition-related changes rarely offer an immediate fitness benefit to their host; rather, they produce neutral mutations that become fixed in the population because of genetic drift. However, in some cases TE activity can result in phenotypic variations.
In this Special Issue, the contributing authors explore these subjects from a range of perspectives, especially focusing on the potential role of TEs in adaptive evolution and on their impact on gene expression both at locus or genome level, with a look to the effect of transposition in determining changes in phenotypic traits.

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 papers will be 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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
