Special Issue Information
Dear Colleagues,
Plant pathogenic bacteria are the causal agents of a variety of diseases that affect a wide range of crops, resulting in a reduction in yields and, thus, a detrimental effect on agriculture. Perceiving pathogenic bacteria is essential for the plant to raise alert and trigger a convenient response. Plants can recognize conserved pathogen molecular patterns through plasma membrane-localized pattern recognition receptors (PRRs), inducing a first layer of immunity named pattern-triggered immunity (PTI). Intracellular receptors (nucleotide-binding leucin-rich repeat (NLR)) can detect virulence factors secreted by the pathogen, leading to a second layer of plant immunity called effector-triggered immunity (ETI). The local recognition of plant pathogens induces a systemic signaling, activating a defense response in the distal tissue (systemic acquired resistance (SAR)). The result of all these layers of plant immunity is the onset of a defense response capable of protecting the plant from the attack of non-specialized pathogens. Bacterial pathogens deploy an arsenal of virulence factors including, among others, effector proteins, toxins and degradative enzymes that target different plant pathways to suppress plant immunity and to adapt to the environment in order to promote bacterial proliferation.
This Special Issue aims to address the diverse responses induced by pathogenic bacteria upon interaction with the plant, including immune responses activated to curb bacterial infection, but also the responses resulting from bacterial manipulation of the host by virulence factors.

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.
