Special Issue Information
Dear Colleagues,
As sessile organisms, plants are constantly exposed to potential attack by pathogens and herbivores and have evolved a diverse array of mechanisms with defense roles. Most prominent are chemical mechanisms of defense including toxic compounds, inhibitory proteins and deliberate cell suicide that plants use to deter or poison pathogens and herbivores. Also important are physical or structural defenses including surface features such as trichomes, cuticle and cell wall that prevent their natural enemies from attacking on plant tissues. Different defense mechanisms can be vastly different in effectiveness against different pests and pathogens and in some cases a highly effective defense mechanism against one type of pests or pathogens may aid attack by a different type of predators. In addition, while plant defense mechanisms reduce damage and mortality caused by pathogens and herbivores, they cost plants in terms of energy and nutrients. Therefore, deployment of appropriate plant defense mechanisms to the right place at the right time is critically important for effective protection against pathogens and herbivores without two heavy cost to plant fitness. Furthermore, pathogens and herbivores are also evolving to counter plant-based defense strategies to ensure their survival and success in invading plants. Research on elicitor recognition, signaling, gene regulation, mode of action of defense chemicals/proteins and the tug-of-war between plants and its natural enemies has been at the frontier over the past several decades in modern plant biology, which has greatly enriched our understanding of the molecular basis of effective plant defense. Innovative approaches are also been developed to explore the basic knowledge of plant defense to develop strategies of genetic engineering and molecular breeding of pathogen- and herbivore-resistant crops.
We invite investigators to submit both original research and review articles that explore all the aspects of the plant defense against pathogens and herbivores. Potential topics include, but are not limited to:
- Elicitor recognition
- Defense signaling
- Local and systemic plant defense mechanisms
- Induction and memory of plant defense mechanisms
- Genetic and epigenetic regulation of plant defense
- Gene expression associated with plant defense responses
- Defense priming
- Chemical defense
- Plant surface and cell wall defense
- Mode of action of defense-related chemicals and proteins
- Counter-defense mechanisms by pathogens and herbivores
- Genetic engineering of plant defense
- Plant defense and fitness tradeoff

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. 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.
