Special Issue Information
Dear Colleagues,
In recent years, numerous factors have contributed to the spread of serious viral diseases in plants. Some current examples include the epidemics caused by ToLCNDV in cucurbits in several countries of the Mediterranean basin, transmitted by its efficient vector Bemisia tabaci, and those caused by the ToBRFV, a seed-borne virus which is considered a global threat to tomato production. The establishment of a viral infection is genetically determined by the availability of host factors necessary for virus replication and movement, and by the balance between plant defense and the viral suppression of defense responses. Continuous planetary changes influence these factors and are relevant to such infections in their alteration of the pathogen’s pressure, the exposure to pathogens, the plant response to infection, or their ability to facilitate the introduction of viruses and vectors into new areas. Furthermore, the expansion of agricultural frontiers leads to greater contact between natural and altered ecosystems, increasing the exposure of plants to new viruses. In particular, ongoing climate change alters the distribution and phenology of plant virus vectors, resulting in the spread of viruses that have colonized or recolonized new areas and new hosts, most often in mixed infections, while global trade leads to the unwilling movement of plants, viruses, and vectors, contributing to their worldwide diffusion.
This Special Issue welcomes original research submissions and perspective and review articles focused on epidemiology, transmission pathways and natural cycles, and virulence and plant resistance concerning new emerging and re-emerging viruses. Methods papers covering the development and evaluation of diagnostic assays for the diagnosis of new emerging viruses are also welcome. Studies aiming at the discovery of new viruses (together with physiological insights into virus and/or host life histories), or at establishing the pathogenesis of viruses correlating to global changes, are also within the scope of this Special Issue.

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 250 words) can be sent to the Editorial Office for assessment.
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. Viruses 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 2600 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.
