Special Issue Information

Dear Colleagues,

Plants have different mechanisms that provide resistance to pathogen attack since they are capable of recognizing and distinguishing what is self from what is not self. This ability to discriminate self from non-self is a prerequisite for the activation of defense mechanisms after an attempted invasion of pathogens. Plants express pattern recognition receptors (PRRs) that recognize molecular patterns associated with pathogens or microorganisms (PAMPs or MAMPs, for Pathogen- or Microbial-Associated Molecular Patterns) and trigger immunity via PAMPs (PTI, PAMP-Triggered Immunity). MAMP is most commonly used in plants since not all microbes are pathogenic. This response is usually temporarily slow and of low amplitude. This defense is considered basal and does not prohibit colonization by the host nor limit the extent of its spread. A second line of defense mediated by resistance (R) proteins allows recognition of pathogen-specific molecules (avirulence proteins, Avr) and triggers effector-triggered immunity (ETI). In this sense, the action of the R proteins would allow for accelerating and eliciting the basal innate defense response. In addition, the immune response to endogenous signals originating from damaged or stressed cells is emerging as a crucial role of the immune system. Endogenous molecules, eliciting activity released from cellular components during pathogen attack or abiotic stress, have been defined as danger-associated molecular patterns (DAMPs). To be efficient, these signals should be pre-triggered or inducible. Any molecule found exclusively inside cells could serve as a pre-made alarm signal. The aim of this Special Issue is to highlight recent advances in the understanding of mechanisms of plant defense response by elucidating immune activation mechanisms and by illustrating plant molecular and physiological mechanism functioning. Multidisciplinary approaches able to describe the function and regulation of the plant immune system are welcome. Researchers can contribute original research findings and review and perspective articles to this issue.

Manuscript Submission Information

Manuscripts should be submitted online at 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. Plants is an international peer-reviewed open access semimonthly 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.
