Innate Immunity in Plants and Stress Responses

Dear Colleagues,

Innate immunity in plants has been heretofore considered to include basal defenses which are activated by extracellular pathogen associated molecular pattern (PAMP) molecules binding to plant cell membrane receptors. This innate immune, or pattern recognition receptor (PRR) defense response has been considered distinct from both systemic acquired resistance (SAR) and what can be considered an acquired immune response involving effector-triggered immunity (ETI). Recently, new insights into the molecular nature of these signaling pathways have provided a more refined understanding of the components of these defense responses and suggest more overlap in their signal transduction pathways than previously thought. The aim of this Special Issue is to encourage research as well as review articles that capture new understanding of these systems. The scope of the work solicited for this Special Issue is broad; studies at the ecosystem, organism, cell, and molecular levels are encouraged. Foci could include studies of the regulation of these defense responses, as well as delineation of new nuances of their operation and efficacy. In many contexts, plant immune responses can be impacted by other stresses imposed on these primarily sessile organisms. Hence, interaction of immune defense against pathogens with other stresses imposed on plants is another area of interest 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 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.
