Special Issue Information
Dear Colleagues,
During their growth and development, plants are often exposed to a wide range of pathogens and pests, including viruses, bacteria, fungi, oomycetes, nematodes, and insect pests. To fight pathogens and pests, plants have evolved a complex, multi-stage immune system. The first line of plant protection is the pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI), which leads to the perception of PAMP, DAMP, HAMP, VAMP (pathogen-, damage-, herbivorous-, and virus-associated molecular patterns, respectively) using pattern recognition receptors (PRRs). However, pathogens and pests can suppress PTI using effectors. The second line of defense, effector-triggered immunity (ETI), develops when effectors are recognized by products of effector-specific resistance genes (NB-LRR proteins). The development of PTI and ETI induces multiple cellular responses and the activation of signaling (activation of the cascade of calcium-dependent or mitogen-activated protein kinases) and phytohormonal pathways, which subsequently leads to transcriptome and proteome reprogramming. Phytohormones play a key regulatory role in these primary immune responses. Salicylic acid (SA), jasmonic acid (JA), and ethylene constitute the central regulatory network of plant immunity and interact with other phytohormones, forming a complex signaling network with many cross-talks. In turn, pathogens, viruses, and insect pests have evolved the ability to manipulate or disrupt plant phytohormone signaling pathways to their advantage through an arsenal of secreted effector proteins. In this battle, the mechanism of RNA interference occupies an important place.
It is also impossible to study the relationship of plants with harmful organisms without the participation of the plant microbiome and its constituent endophytic and epiphytic plant growth-promoting bacteria (PGPB), which support growth and protect the macro-organism from abiotic and biotic stresses. PGPB can directly regulate the abundance of harmful organisms, as well as affect the defense systems of the plant itself, triggering induced systemic resistance (ISR).
This Special Issue on “Regulation of Plant Immunity” welcomes original research and review articles that present the latest advances in the mechanisms of regulation of plant immunity. We also focus, among other things, on effector biology as a new direction in phytopathology. New molecular approaches or tools (including the mechanism of RNA interference) to study plant–pathogen interactions are also welcome.

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 Plant Biology is an international peer-reviewed open access quarterly 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 1200 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.
