Plant Virus Transmission by Vectors 2024

Dear Colleagues,

In an increasingly globalized world, plant diseases caused by viruses are of agricultural importance, causing serious losses. Most plant viruses are vectored by insects, mites, nematodes, custuta, and fungi. Among them, insects are the most common vectors, including aphids, thrips, leafhoppers, planthoppers, and whiteflies, which transmit several agriculturally important viral diseases. The process of plant virus transmission by vectors involves viral acquisition and transmission, viral circulation in the vector(s), and the interaction between the virus and the immune machinery of the vector, and may even involve viral propagation in some cases. Recently, reports have shown cross-kingdom virus–vector–plant interactions during viral acquisition and transmission. Uncovering the orchestration between these interactions at a biological and/or molecular level is crucial in order to understand the plant virus cycles in the vector(s) and the viral cross-kingdom interactions between the vector(s) and the plant hosts.

In this Special Issue, we welcome a wide range of articles, including original research, short communications, and reviews, which focus on the discovery of emerging plant viruses or vectors, tracing the source of plant viruses transmitted by vectors, virus–vector interactions, or virus–vector–plant interactions. Studies with computational approaches or bioinformation are also welcome. Topics of interest include observations and/or underlying mechanisms of (i) the vector range of plant viruses, (ii) the host range or source of plant viruses transmitted by vectors, (iii) the acquisition, transmission, adaptation, infection, and evolution of plant viruses in vectors, (iv) the immune response of vectors to plant viruses, (v) the co-evolution of plant viruses and endosymbionts, (vi) the cross-kingdom signal delivery of viruses in vectors to plants, (vii) the plant response to vectors or viruses, and (viii) the diagnosis, identification, epidemiology, and control of plant viruses.

We hope to produce a collection of papers on topics related to plant viruses and their vectors, in order to provide valuable information to improve our understanding in this area. We look forward to receiving your submissions for 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.
